Classic and Draft are the main game mode people play, but there are several others, and I have covered key information about each one below. The other game modes can be fun on occasion, especially if you can't get 10 players in your lobby. I have also covered some game mechanics that affect the game modes in this guide.

The task pool mainly applies to Classic, Draft, and Corruption, but also to Trick or Treat in a lesser extent.

With the task pool, there is a total number of tasks that need to be completed by all living geese to earn a task win. The relative size of the pool can be adjusted in the settings for Classic, but not Draft. The actual number of tasks that need to be completed is a multiplier based on the number of players.
Each goose is assigned 4 tasks initially plus any global tasks for the map. Once one task is complete, another is assigned. As long as you are alive, you will continue to be assigned new tasks until the pool is filled. You cannot run out of tasks while alive.
When you die: if you have completed 8+ tasks while alive, you will have no tasks when you die. If you completed 8 tasks or less, you will be able to complete 8 minus the number of tasks you completed while you were alive, but they will be fake.
Ducks: same as geese, except you have a maximum of 2 fake tasks at a time plus tasks to activate sabotages.
Most Neutrals: similar to geese, except your tasks are all fake.
Dueling Dodo you have 3 fake tasks as long as your dodo partner is alive, the completion of which will give you the ability to kill your dodo partner. If your dodo partner dies before you finish your third task, you will switch to having a standard neutral task pool system.

Here are the main differences between a game that is Public or Private

Public Games:

• Cannot change map
  
• Cannot change game mode
  
• Can disable voice chat (at time of creation)
  
• Cannot have role reveal
  
• Cannot have privacy mode
  
• Cannot spectate individual players
  
• Can be found through "Find Game" (unless the lobby is locked or in progress)

Private Games

• Can change map
  
• Can change game mode
  
• Cannot disable voice chat or proximity chat
  
• Can have role reveal
  
• Can have privacy mode
  
• Can spectate individual players
  
• Cannot be found through "Find Game," players must have the lobby code, get invited, or join through a friend.

Classic is the primary game mode, and it has been part of the game since its launch. When you start the game, you are assigned a role based on the lobby settings. Geese win by completing their tasks or voting out all the killers, and the ducks win if the geese fail to fix certain sabotages, or if the number of living ducks equals or exceeds the number of living non-ducks (excluding Falcon/Pelican). Each role has a special ability, and you never know what roles are in each game until players prove their role. It is much easier to claim a role you are not as a result.

Achievements: Win 1,000 games of Classic or Draft.

Pros:

• Highly customizable
  
• Faster start time
  
• Role claiming is weaker because Assassin is always a possibility
  
• Creating balanced lobbies with a small number of players is possible

Cons:

• Creating fair lobby settings requires a certain amount of game knowledge
  
• Settings may need to be changed between matches to keep games fair
  
• While settings can be saved, you may need a preset for each map

Other Factors:

• There is more room for creativity regarding role claiming
  
• You have no choice in your role

Selecting roles
For each role, you have three options: off, question mark (?), or check mark. Players cannot be assigned roles that are off. Roles that have a check mark are guaranteed to be in the role pool, and most roles should be check marked or off. Roles with a ? have a chance of being in the role pool, and will be completely ignored if a certain type of role is filled by roles with check marks. Selecting ? for a lot of roles will result in players getting basic goose/duck, but ? can be good for Neutral roles as an optional choice (it makes the distribution of Neutrals less consistent). Overall, you have to have most of the goose roles on (and check marked) if you want to ensure that no one gets basic goose.

Being Creative with Role Selections
If your lobby really likes a certain duck role(s), you can check mark the role(s) and question mark everything else (or even turn some off). If your lobby really hates a role, you can turn it off. For Neutrals, you can choose any distribution from none (all Neutrals off), to four every game (4 Neutrals, all check marked). You can turn a Neutral off if that role keeps getting free wins, or you can alternately turn a role on to counter a gameplay issue (such as Pigeon to counter grouping). You can even alternate a set of roles to ensure that these roles are never present in the same game (I've seen this with Lovers and Hitman/Bodyguard many times).

Detailed Role Selection Suggestions:
For detailed role suggestions based on lobby size, check out this guide.

Instead of being randomly assigned a role, you are randomly assigned a number from 1-16, and this number dictates the order in which players pick their role. Each player has fifteen seconds to choose one of three roles or random, and random is picked automatically at the end of the timer if no selection is made. Role selection is the only functional difference between Classic and Draft, but the gameplay experience differs significantly. Draft was released on 9/19/2022 in update 2.09.

Achievements: Win 1,000 games of Classic or Draft.

Pros

• You have some control over the roles you play
  
• Creating a lobby is quick and easy regardless of map or lobby size
  
• No need to adjust settings between games

Cons

• Games with less than 10 players can feel unfair because all roles are still possible
  
• Games take longer because of the Draft
  
• Role claiming is stronger because many games are confirmed to not have an Assassin

Other Factors

• There is often a basic goose
  
• Less room for creativity when claiming a role

Roles in Draft
All roles that are normally available on each map can show up in Draft. The game tries to make sure the Duck roles are filled early, but not necessarily the Neutrals.. You can get any viable role that hasn't been chosen by picking random (which can be a Duck or Neutral if those spots have not been filled, or basic goose). Dodo changes to Dueling Dodos if a second player picks Dodo. There is often a basic goose. The info button only shows roles that were not chosen at random, even though other roles are possible.

Draft Exclusions and Added Settings
You can exclude (ban) up to 8 roles of any combination of geese, ducks, and neutrals to improve your draft experience. These can be saved as presets and changed before each game. Banning Dodo bans both Dodo and Dueling Dodo, so you can technically ban 9 roles.

You can also manually adjust the number of ducks and neutrals by deselecting the "auto" option next to the slider for these groups, which also gives you move control over your Draft experience, as some of the default presets (like 3 ducks on 13) are a bit unbalanced. You can also adjust the size of the task pool to make task wins more feasible. These updates were added in patch 3.10.

Lovers and Hitman/Bodygard in Draft
These role sets were added to draft in 2.27. There can only be one pair in a game. Once the first half of a pair is selected, the other half of the pairing will be made available to the pool. If no one picks the second half before the final player, the final player will be forced to select the second half. When either half is selected, it will show that the player chose Random.

Draft Default role distributions:
5-8 players: 1 duck, 1 neutral
9 players: 2 ducks, 1 neutral
10-12 players: 2 ducks, 2 neutrals
13 players: 3 ducks, 2 neutrals
14-16 players: 3 ducks, 3 neutrals

Description: A single duck tries to kill every goose in the lobby before the timer runs out. There are no meetings or sabotages, but the duck can still vent. Geese are assigned a fixed number of tasks, and each task a goose completes will reduce the timer by 4 seconds if alive and 1 second if dead. The timer duration is set automatically and is based entirely on the number of players. You only need 4 players to play Goosehunt. Goosehunt has been around since the beta Steam release.

Achievements: Win as the duck 100 times; win as a goose 500 times.

Size of Task Pool: Normal/Large.
Vision: Default is usually good, bump it to medium for duck if geese normally win, give duck flashlight vision if the duck is usually winning.

Since you reduce the timer far more for completing tasks while alive, focus on completing tasks that are quick and close to you. Starting a multi-part task can be helpful but is not a priority; long tasks are the lowest priority. Hiding from the very start of the round is not advisable, but if you are alive with only 1-2 geese left you need to find a good hiding spot and fast. Once dead, speedrun your tasks following the same general principles above. Unlike most game modes, grouping up is a bad idea because the duck can usually kill multiple players in quick succession due to their faster walking speed. Pay attention to who's around you and to the kill feed, as this can give you an idea of where the duck is, so you can try to avoid them. If you know who the duck is, try to tell other players (prox chat).

You walk faster than the geese so use that to your advantage. You obviously want to be killing as fast as possible, so just kill whoever is most available. Chasing geese you are already next to until you can kill again is helpful. Just walking around the central part of the map for the first half or so works well. Spamming your kill button can be helpful (especially if flashlight mode is on). If you're struggling to find people, be sure to vent around to get across the map quickly. It doesn't take long to find out where the good hiding spots are, so be sure to check these once there are only a few geese remaining. Note: You can still kill players with the airlock if visuals are on.

Description: Red team vs. blue team. Red team is all ducks that can morph and blue team always has a vulture but will also have a Falcon if there are enough players (7 or 8 I think). Red team wins by killing blue team and blue team wins by staying alive until the timer runs out. The blue team's vulture can eat bodies to reduce the timer. Ducks can kill other ducks. Dine and Dash was added within a couple months of the beta release on Steam and replaced the Hide and Seek game mode.

Achievements: Kill 1,000 players; win 100 games as the Diners (Vulture/Falcon); win 100 games as a duck.

Better with proximity chat.

While you can technically win by killing everyone you see on-sight, it is better to try to try and find another duck to clear by morphing into them (they're clear if they can do the same). Then, go around with them trying to kill anyone else you see. You should be able to win this way, just be aware that the Vulture may be trying to hide. Knowing the hiding spots for Goose Hunt can be helpful.

If the falcon is in play, try to eat the bodies they kill for you before the ducks can kill (usually the first 30 seconds or 2-3 ducks dead). Your main priority is to stay alive, so hiding once the ducks can kill is advisable. Once there are only a couple ducks left it becomes much safer to go out and eat bodies. You still don't want to be seen eating a body by any ducks, especially in a lobby with prox chat.

You have the shortest kill cooldown of anyone in the lobby. You basically want to kill as many ducks as possible before the duck kill cooldowns come up. After their cooldowns are up, you want to continue to kill as you can, trying to hide when your cooldown is down. Being seen killing is not an issue as long as you aren't chased, but killing in a group of ducks is not advisable as any living ducks who see you kill early will know your role, and they will subsequently try to hunt you down. Sticking with your vulture partner can actually be a detriment; your main goal is to reduce the number of ducks by killing them off.

Description: Vampire or Mummy versus villagers; survival. Instead of killing, the Vampire turns its victims into Thralls (which happens 15 seconds after the Vampire bites them). Thralls can turn other Villagers into Thralls. Villagers can kill Thralls on a 5 second cooldown. Thralls respawn where they died after 15 seconds. The Vampire wins if all Villagers are converted to Thralls, and the Villagers win either by voting the Vampire out or if at least one Villager is alive when the timer ends. Villagers must collectively complete a certain number of tasks to call a meeting (usually 1-2 meetings per game, depending on lobby size). If and when there is only one Villager remaining, the timer will reduce to 35 seconds (if applicable). Trick or Treat was added in update V0.99.9 on 9/27/2021, and the mummy was added in update 2.10 on 9/28/2022.

Achievements: Finish 15 tasks in a single game; survive as the last villager 50 times; win 100 games as a monster; win 250 games as a villager.

Only available on MM/GC/TB. Better with proximity chat and role reveal.

You want to completely speedrun tasks until Thralls start appearing, and even after just one or two are around. If you see a Thrall, try to kill it, but be aware that your cooldown resets if you hit the button at all (so you can't spam the button). Also try to be somewhat aware of who is around you, so you know who among those players got turned into Thralls come the next meeting (if any). You always want to vote someone out at the meeting, even if you are not sure who it is. There is often only one meeting. If you are the last Villager, just ignore your tasks and either try to run or hide (Goose Hunt style).

With Mummy:
The main difference is that you don't have to worry as much if you see a single Thrall, but beware groups of Thralls and the Mummy. You cannot kill Thralls once they've grappled you, but you can still do tasks. Grouping up with other Villagers later in the game is suggested.

With Vampire:
You have flashlight vision. Just wander around and try to kill Villagers; head for the nearest player if Blood Moon is active. If you're in the vicinity of good hiding locations, it doesn't hurt to check them, as some Villagers prefer to hide.

With Mummy:
If three thralls grapple the same Villager, that Villager dies. You want to try and group up with at least 2-3 other Thralls so that you can quickly kill any Villagers you find. If you can't find any Thralls, try to find a lone Villager and grapple them, and you can use voice chat to try and call for other Thralls.

Knowing how to hard fake tasks is critical for playing this role effectively. Fake tasks when your "kill" button is not up, and then make sure to convert another player when you can. You pretty much want to be biting Villagers as fast as possible, but be aware of converting one person out of a pair (individuals and large groups are fine), as they may be able to pin you down as the Vampire off the one interaction. Take advantage of sabotages whenever possible once you have at least 2 Thralls, or immediately after meetings. Blood Frenzy is the go-to as the decreased Villager makes it much harder for Villagers to kill Thralls, and the movement speed is usually enough to help Thralls find Villagers. Blood Moon is the best choice when there are 1-2 Villagers remaining. You can hide, but it is highly inadvisable for two reasons: 1) it proves you are the Vampire to any Villagers who see and 2) it serves no real purpose (since you can't be killed by Villagers or Thralls).

You can only kill Villagers and sabotage while you are transformed as the Mummy, and you have a 5 second kill cooldown, but you move slower. Villagers will be able to tell you're the Mummy if they see you transform, or by process of elimination based on the Villagers they've seen. You can either just run around and try and kill everyone, or you can create a handful of Thralls and then let them do the work for you while you fake tasks. However, you don't want other Villagers to see you near Thralls since Thralls can't grapple you. Make sure to call sabotages, but again you have to be in mummy form. You can hide, which might be beneficial near the end of the round, but again, don't let any Villagers see. If playing with Proximity chat, be sure to MUTE YOUR MIC while transformed as the mummy.

Hanging Out is considered a game mode on the menu, but it isn't quite a game mode in the traditional sense. The Lounge, exclusive to this mode, is a place where you can chat with other players and play mini games without the pressure of an actual game. The map features several private rooms for private discussions, as well as larger rooms for chatting and hanging out. The Lounge also doubles as a sort of launch pad where you can take the players from The Lounge to another map to play a regular game mode. Hanging Out was added in update 1.06 on 1/18/2022.

Tööt
Tööt is currently the only mini game available in The Lounge. You can read about how to play Tööt here, credit to firebreaker2262.

Tastes Like Chicken (TLC) is notably different from any other game mode, and it is more of a team-based battle royale, except there are no resources or weapons to gather.

• TLC requires a minimum of 8 players.
  
• Players are divided into 4 teams (Red, Blue, Green, Yellow).
  
• Each team has one Chicken and any chosen combination of the other four roles.
  
• Players get to choose their role in a randomly selected order (sort of like draft).
  
• The pre-game voice chat is separated by team, so teams have time to strategize while selecting roles.
  
• You cannot down or kill your own teammates.
  
• If teams are not even, teams with fewer players are provided a free revive of the first killed player (if the Chicken stays alive).
  
• There is a circle at the edge of the map that shrinks over time, and you will die if you stand in it for 5 consecutive seconds.
  
• The last team standing wins. Otherwise, ties are decided based on other stats like most kills and most downs.
  
• Available on all maps except Nexus Colony (split sides doesn't work with the circle).
  
• The host has control over who is on which team (seen below).

There are 12 achievements unique to TLC; only the general wins award cosmetics, with each having a banner. Please note, you will not make progress if you do not get the egg crack screen at the end of the match (I've seen plenty of matches of TLC be too short).

• Win 25 and 250 games of Tastes Like Chicken
  
• Win 25 games as each role
  
• Earn each accolade (end card) 25 times. Kills and Revives are both unique to Chicken, Drags is unique to Undertaker, and most saved is unique to Bodyguard. Downs can be earned as any non-chicken role.

Using your kill button as any role besides the Chicken will only make enemy players prone (downed). Downed players can still move, but they move slower. Downed players can be killed by an enemy Chicken or revived by an ally Chicken. This is why, whenever possible, it is best to work with your team to down and immediately kill an enemy player before their Chicken can revive them.

Abilities: The Chicken can kill downed enemy players and revive downed allies.

Notes: If the Chicken is downed, they will automatically revive after about 5 seconds if they stay alive.

Strategy: You want to stay behind your other teammates, but not too far. If you are entering an engagement, you want to be able to swoop in and kill an enemy that your ally has downed, or quickly revive a downed ally. You want to disengage while your abilities are on cooldown.

Ability: if another player in range would be downed, you are downed instead.

Notes: This is the primary defensive role. You do NOT want more than 1 on your team, and it is only advisable in teams of 3-4.

Strategy: You want to stick with your Chicken at all times. You are there to ensure that a single enemy cannot down your Chicken without downing at least one other player.

Ability: You are invisible to enemies until they get within range of you (the larger circle around your character).

Notes: Can be both offensive and defensive depending on how it is played.

Strategy: You want to keep a bit of distance from your allies, as you are there to alert your team to danger, since you can see enemies before enemies see you (unless they are also using Camo Ducks). You are there to help your team decide whether they should fight, disengage, or flee.

Ability: You can drag downed enemies at a reduced speed.

Notes: You will let go of a downed enemy if you are downed.

Strategy: Fully dragging an enemy is only advisable when that enemy is actually or mostly alone. The more useful purpose of this role is to temporarily hold a downed player, thus making it harder for them to flee and easier for your Chicken to finish them off.

Ability: You turn into the player you most recently downed.

Notes: You revert back to yourself after a certain period of not downing any players.

Strategy: You are the element of confusion. You are not entirely safe trying to blend in with the team whose color you currently are, but you can use the distraction to help down an enemy. Works better on teams of 3-4. Works well for aggressive teams.

No matter what, you want to stick with your team. The second most important thing is protecting your Chicken. While possible, it is extremely hard to win if your Chicken is dead.

The three basic strategies you can switch between are full defensive (finding a room and camping it), mixed (moving around, usually at a slow pace, but avoiding dangerous areas), or aggressive (moving around at full speed, or camping a dangerous area). You may shift between multiple strategies in a game, but certain role combinations are more suited to certain strategies.

You have to make sure to avoid the circle. Playing nearer to the center of the circle is usually more aggressive, whereas sticking closer to the edges is much more defensive. You can abuse the fact that you only die from 5 consecutive seconds of standing in the circle. For instance, you can move through one area that is "closed off" to get to another safe area, which can even catch an enemy team by surprise. You can also dip in and out if you are trying to wait out cooldowns.

The Bodyguard should be on the chicken, and the other ducks should be together, either ahead of the Chicken while moving, or in a position to watch for enemy teams if the Chicken is hiding in a room. The Chicken should move forward in engagements to kill enemies or revive allies, and should back off and verbally warn teammates when they are on cooldown. The Chicken can re-engage once they have cooldowns again.

Whenever you encounter an enemy team, you have to decide whether to engage. It can be dangerous to engage if you think you are in a location where another team may attack you from behind. While downing the enemy Chicken is huge, securing a kill is usually the better strategy. Always make sure to disengage when your kill is on cooldown, and then you can re-engage when it's back. Always head straight for your Chicken if you are downed. Disengage completely if your Chicken is downed.

Hoot and Seek is a modified version of hide and seek with sniper rifles. The game mode is hunters (spotters and snipers) vs. owls. The hunters win if they shoot the owl before the owl can fill up the task bar.

Some notable features of this mode include:

• No set time limit.
  
• Global voice chat
  
• 2-5 players (owl and sniper on 2)
  
• The map is filled with dozens of NPC characters that move and act like real players (they can fart)
  
• All non-spotter players and NPCs have completely randomized cosmetics, and all players are the same color (random each match)
  
• Available on all maps besides Nexus colony
  
• Spectators are only available in private games (up to 11 spectators).

The following can increase progress on the task bar:

• The owl completing a task
  
• The sniper shooting any bird besides the owl
  
• The owl pick pocketing a sniper

Achievements: Win 100 games as each of the three roles (Spotter, Sniper, Owl)

The spotter can use their ability to scan a radius around them to see if the owl is within that radius. Green means they are, red means they aren't. The scan is a snapshot, so it is important to consider that the owl can move out of a green circle or into a red circle. It is best for multiple spotters to work together to narrow down where the owl is at any given time. If a spotter thinks they know who the owl is, it is helpful to follow that player, continue to use the ability, and communicate the location. Once synced up with other spotters, it is normally useful to use the ability constantly. Scanning edges of maps can be powerful. Spotters can be NPCs.
Snipers can kill any player. Snipers need to work carefully with spotters to determine who the owl is. There are far too many birds running around for shooting randomly to work. Keep an eye out for birds moving faster than normal, morphing, or the task bar shooting up significantly after someone passes you by. It can be helpful to follow a spotter so that you can be nearby if they get a good read. You usually don't want to stay in your scoped view for too long, as it leaves you vulnerable to pick pocketing. The sniper's reticle can be seen by all players.

How you play the owl sometimes depends on the type of lobby you're in, but you have many tools at your disposal. You usually don't want to entirely rely on tasks, and you want to make sure any tasks you do are relatively quick so you can react to threats. Seeing a reticle near you is not always reason to panic; try to listen to the positions or cosmetics of the birds the hunters are suspecting. It is usually helpful to walk out of green circles and into red circles if you can do so without drawing attention.
Lights Out
This ability temporarily blinds all other players and gives you a speed boost. This can be useful for evading a sniper reticle or getting away from someone on your tail.
Morph
This works just like the morphling's ability. As usual, you don't want to be seen morphing. Good to use if players know what you look like. You can morph during a lights out. You can morph into a spotter (although you don't want to do tasks disguised as a spotter).
Pickpocket
This is a bit of a high risk, high reward ability. You get a lot of progress for doing it, but if the sniper sees you do it, they can kill you right then and there. You can only pick pocket snipers.
Reset/Reshuffle
All players are teleported to a new, random location, and their cosmetics are randomized. This is your most powerful ability, and realistically you can use it once per game. Only use this if you are in imminent danger of being shot.

Task Race is a seasonal game mode that is only available during certain events. Players race to complete as many tasks as they can within the provided time limit.

In Task Race:

• All players are geese.
  
• There are no deaths and no meetings.
  
• The timer replaces the task pool.
  
• Global tasks are already completed (NC/TB), and Cameras/Intercom are disabled
  
• Each player can easily complete 8 tasks.
  
• Games are long enough to earn pet bonuses.
  
• Task Race is not available on Nexus Colony.

Achievements: Most achievements that are based solely on tasks can be earned in Task Race. Task Race has no exclusive achievements. Achievements for winning games do not count; I am not sure about completing games.

Tips for getting on the podium

• Quickly check your map after every task for optimal task pathing
  
• Completely avoid tasks that take a long time (such as the well task on Bloodhaven), and only tasks that take a long time (tasks that take a moderate amount of time are usually worth it).
  
• Use the Escape key to quickly exit a task after it is completed
  
• Don't pay too much attention to the timer, just focus on doing tasks quickly and optimizing your path between the tasks you are given.
  
• If you have tasks whose parts are quick to do but require you to wait awhile (test hot water, send signal), prioritize starting these tasks so you can complete them when you loop back around (ignore during the last minute).
  
  

This is a custom game mode that can be a lot of fun. You will have to ask the geese not to call meetings, but the suggested settings below help discourage meetings. It's also common to ask that the Demolitionist not call sabotages with timers, but sabotages like lights and doors are fine.


Map: Jungle Temple or Ancient Sands (best), or map of choice

Game mode: Classic

Ducks: 1
Task Pool Size: Normal/Large (adjust as necessary)

Discussion/Voting Timer: 15 seconds
Emergency Cooldown: 40 seconds

Roles
Gravy (optional)
Demolitionist
All other roles: OFF

Sabotage Cooldown: 70 seconds

Speedrun tasks, prioritizing shorter tasks when possible. If you can figure out who the demo is, try to pass the bomb back to them, but otherwise don't worry about passing the bomb. Focus on tasks.

Don't worry too much about revealing your role. Try to give out bombs on cooldown, and vent, hide, or go into the fog if necessary to make sure no one passes a bomb back to you.

Very early in GGD's history, there was a hide and seek mode. It was replaced by Goosehunt, but you can recreate it. Flashlight vision was an integral part of the mode, and all tasks had to be completed for the geese to win (which only really works with Goosehunt). There are two ways to recreate it:


Gamemode: Goosehunt

Goose Vision: Medium, Flashlight on
Duck Vision: Low, Flashlight on


You will have to ask players to not report bodies or call meetings, as well as ask the duck not to call sabotages that have to be fixed like Reactor, Fire, Feed God, etc (doors and lights are fine). If someone intentionally reports a body or calls a meeting, vote them out.

Gamemode: Classic

Random Start Positions: On
Ducks: 1
Task Pool Size: Normal to X-Large depending on lobby size

Discussion Timer: 15 seconds
Voting Timer: 15 seconds
Emergency Cooldown: 40

Roles:
Gravy (optional)
All other roles off

Goose Vision: Medium, Flashlight on
Duck Vision: Low, Flashlight on

Kill Cooldown: 10
Sabotage cooldown: 70

Corruption plays a lot like Classic mode, but tends to be slanted more in the ducks' favor and can be confusing to understand at first. The short explanation is that there are corrupted items scattered across the map that the ducks can always see, but they can be interacted with by all players at all times. Ducks can collect these to power up their abilities, while geese want to avoid them to keep their normal vision. Noticing a player purposefully collecting corruption can indicate that they are a duck. There is also a short time where all players can see corrupted items, and when simultaneously all players temporarily turn into demons, reducing the amount of information geese can collect, and making it easier for ducks to get free kills. Corruption mode was added in update 2.24 on 6/1/2023. Corruption was initially released as an inseparable part of the Bloodhaven map, but it was separated due to the high number of players who wanted the Classic experience on Bloodhaven without the complex new mechanics.

A more in-depth explanation of how corrupted items, the day/night cycle, and demon forms can be found in THIS guide under "Bloodhaven (BH) CORRUPTION MODE."

Role Group: Neutral
What it does: You can corrupt other players. The corruption cooldown increases for each time you’ve used it this round. The Crow hunt starts when all players are corrupted for any reason. You win if you kill all other players during the Crow hunt. Your ability lets you see the location of players you've corrupted in real time on your mini map (doesn’t work at night before you’ve ascended).
Purpose: Corruption mode version of Pigeon.
Special Interactions: Will NOT report Canadian.
Achievements: Win 75 games; kill four or more players in one swoop; die after ascending
How to play: Staying alive is the most important thing. Most players will become corrupted for one reason or another, so don't go out of your way to corrupt players, but make sure to get out of the area if you do. Make sure to do some tasks if you become corrupted. Once the crow hunt starts, use your ability to check for corrupted players, and just run around the map as fast as you can. You can't hesitate if you want to win.

Once the last living, non-eaten player becomes corrupted, the Crow ascends, physically transforms, and all players will be receive an alert. The Crow gains a kill button (no cooldown), a major speed boost, and becomes invincible. The Crow can use its ability to see the location of all corrupted players in real time in order to hunt them down. The Crow will be able to kill any number of players within its kill range, so you want to split up once the Crow Hunt Starts. All other win conditions are suspended until the Crow Hunt ends or the Crow wins. The Crow dies if the timer runs out. Bodies cannot be reported and meetings cannot be called during the Crow hunt. If the Crow dies after ascending, other win conditions are reinstated, and the game will either continue as normal, or another role group will get the win.

Role Group: Goose
What it does: During the day when you aren’t corrupted, you can check to see if another player is corrupted (via a saint or corrupted icon). Ducks always show as corrupted.
Purpose: Corruption mode version of Detective.
Special Interactions: Players can become corrupted from the map or from the Crow, so non-ducks can show as corrupted, even earlier in the game.
Achievements: Win 75 games; identify 500 corrupted birds
How to play: Detecting corruption is more useful the earlier in the game you can detect it. Most players will become corrupt over time, from the map or from the Crow, so you have to be more skeptical of detecting corruption later in the game.On the other hand, someone who is not corrupted is cleared from being a duck. There isn’t much point in using your ability while you’re in demon form, as the chances of you sticking around the player long enough to discover the reading are low, unless you know night is almost over.

Role Group: Goose
What it does: Whenever you become corrupted for any reason, you can kill another player.
Purpose: Corruption mode version of Vigilante.
Special Interactions: Will report Canadian. Can claim Gravy’s bounty.
Achievements: Win 75 games; kill 5 non-geese in a single game
How to play: You’ll want to learn where to find corruption so you can get your kill button quickly, but you also don’t want to try not to collect the last corruption until you are near a person you want to shoot. Try to pay attention to other players purposefully collecting corruption as you are, since those players should be good targets. Killing at random early in the game is not a good idea, but it’s safer to do later in the game, especially if you think most of the ducks are alive. Make sure to do a few tasks after taking your shot so you can clear your corruption and repeat the process. You can report your kill if there is no High Priest, or you can try and save your kill button for when it turns to night and your identity is better hidden. You can also pair up with another goose, who will act as a guide you while you're corrupted, so you aren't shooting blindly.

Role Group: Goose
What it does: You are immune to the effects of corruption. You can still become corrupted.
Purpose: Help balance the inherent advantage ducks have on Bloodhaven.
Achievements: Win 75 games; collect 25 corrupted items in a single game.
How to play: You can mostly just enjoy the fact you will only be a demon at night. However, You are the only goose that can safely collect corruption, so you can make a point to collect nearby corruption to reduce the amount the ducks are getting (be aware of High Priest). Also, as the one person who can't be corrupted, be sure to pay attention to your surroundings, especially later in the game. You may be the only one who can see who is who. You can also help guide players who are corrupted, especially the Demon Hunter.

Role Group: Goose
What it does: You can compare the corruption of two other players once per round, via an "=" stitching or "X" stitching. You can see the button above both player's heads, and the button will not change once stitched.
Special Interactions The comparison is made when you select the second player, so it is possible for the first player to change their corruption status between when you select them and when you select a second player.
Achievements: Win 75 games
How to play: Early game, this role can work a lot like Inquisitor, where a difference in corruption between two players could easily mean one is a duck, and an equals meaning both players are either ducks or non-ducks (latter is especially useful). Later in the game, you have to click one player you trust and communicate the corruption status of and another player you are trying to check (ideally, your trusted friend should NOT be corrupted so you can detect a duck). It's almost worth writing the results down because the role is tricky to track and understand.

Role Group: Duck
What it does: As long as you collect 6 corrupted items between meetings, you can attempt to assassinate a non-duck in each meeting. You can’t die from guessing a player’s role wrong. You will be able to take a shot if your icon shows as fully corrupted (you do not become corrupted).
Purpose: Corruption mode version of Assassin.
Special Interactions: Will report Canadian. Cannot assassinate Gravy or classic goose. All players hear a gun cocking and then clicking if you attempt to shoot and miss.
Achievements: Win 75 games; successfully shoot 3 or more players in a single game
How to play: Make sure to collect enough corruption to take a shot in every meeting. As long as you have a shot, there is no reason to not attempt a shot (unless you’re trying to fake being dead). Neutrals are by far your best target, as you can attempt to shoot any non-duck being voted out as Dodo, or you can even just try and guess who the Crow is. If you know a player is one of two roles, you can try again next meeting if you miss. You’ll want to shoot shortly after voting time starts to avoid missing the opportunity to shoot.

Role Group: Duck
What it does: During the day, you can perform a ritual on a body to make it disappear. Successful rituals generate corruption, which can be beneficial to you, or be left to corrupt a non-duck.
Purpose: Corruption mode version of Cannibal.
Special Interactions: Cannot perform the ritual on Demolitionist victims. Will report Canadian.
Achievements: Win 75 games; conduct 5 or more rituals in a single game
How to play: Try to only kill if you think you'll be able to immediately perform the ritual, or if you think you can run away. If for some reason someone walks up before you use your ability, just report the body or explain it away.
Performing the ritual is more risky if there is a Crow and/or later into the game. Corrupted players will see the generated corruption, and they may be able to kill you, or may be close to becoming un-corrupted (so they will see your identity). Whether you pick up the corruption or leave it is up to you, but the corruption pattern is evidence of a body, so I would say collect it if you can.

Role Group: Duck
What it does: You cannot kill normally. You can only kill by collecting corruption and then using your ability. You die if you don't kill at least 4 players with your ability.
Special Interactions: Cannot be the only duck. Will NOT report Canadian. Your ability will not kill other ducks.
Achievements: Win 75 games; use your ability to win the game.
How to play: Given how it works, Sin Eater's kill is very situational, and it is often better to not even initiate a kill than to risk having players figure out the killer is you (or waste your kill). You want to manage the amount of corruption you have at all time so you can kill if the opportunity presents itself. Chatting with other players to try and form a group can be a legitimate strategy for using your kill effectively. You want to get right in the center of the group and press your kill twice as fast as you can to ensure players don't run away. Make sure that the three is not counting a fellow duck.

• Your kill button looks like three souls with a number at the bottom corner, rather than the normal symbol.
  
• Collecting corruption increases the number. The number must be 6, 7, or 8 to initiate a kill. The number cannot go higher than 10. This number decays over time but does not reset at meetings.
  
• Clicking the button once initiates the kill. A ticking sound can be heard once you do. You are now a ticking time bomb. From here, you have two options.
  
  • 1) Press the space bar again. An explosion can be seen and heard. All players in range of you will get blown up, leaving only feet.
    
  • 2) Wait for the timer to end. The ticking will stop, and nothing will happen.
• You will die if less than three other players are killed by the blast. Otherwise, you will live. You will still win the game if you kill all living players by using your ability, even if it's less than 4.
