The changes include the following:

- Changed the Custom Mutations icon on the main-menu.

- Completely revamped all ZSL events to automatically save scores and display a HUD.

- Removed the Survivor bots in two-player Mutations, hopefully fixing an issue to allow players to select the Survivor they want to play as.

- Added 'Survivor VS Survivor' Mutations, where you go head-2-head against other Survivors.

Gun of the Gods (SvS): Survivors are armed with only a Magnum that kills in 1 shot. Survivors can respawn when killed.

Last Man Standing: Survivors weapons keep switching. Survivors do not respawn when killed.

Psycho Survivor: One Survivor is randomly chosen as the Psycho, who's job is to kill the other Survivors. All players will have a chance to be the Psycho.

Pyro Rage: Survivors are armed with only a Molotov. Survivors can respawn when killed.

- Added "Target Acquired", in this Mutation each Survivor earns points for killing the target SI which changes after each kill. The Survivor with the most points wins!

- Added "The Last of Us", only Common Infected spawn in this Mutation. But if a Survivor dies, they stay dead for the rest of the game!

- Added "The Very End Of You", only SI spawn in this Mutation. But if a Survivor dies, they stay dead for the rest of the game!

- Added "Sky Burst", the Survivors have only Pipe Bombs against Hunters and Jockeys.

- Added "Gun of the Gods", the Survivors have a 1-shot kill Magnum against SI.

- A few minor tweaks to various Mutations.

The changes include the following:

- Added "L4D2 Co-op" and "L4D2 Versus", in this Mutation nothing but L4D2 SI, items and weapons spawn. You wont find anything from L4D1, with the exception of the Witch and Tank.

- Changed modename for Immoral Support from "ally" to "immoral".

- Updated "Bombing Run", "Fire Storm", "Call of Boomer" and "Immoral Support", removed all weapon spawns from the map to prevent the Survivors from picking them up.

- Updated "Left 4 Gun Game: Special Edition", tweaked the spawn rate and amounts of certain SI types that spawn.

- Updated "Call of Boomer", lowered the Tanks health so they die in one punch from an Infected.

- Updated "Tankball Versus" and other Tankball modes, changed the Tank's health back to default and prevented all damage delt to the Tank by the Survivors. This was done to prevent the Tank from being stuck if the Tank would fall in water.

- Re-added missing modes, now they're playable again:

All Solo Mutations, Madness, Last Duo On Earth, Jimmy Gibbs Only!, Realism Survival, Chaos, Insanity, Hardcore Common Problems, Hardcore Death's Door and Hardcore Special Delivery.

The changes include the following:

- Moved all Mutation modes from the gamemodes.txt file to their own <modename>.txt file, which prevents conflicts with other gamemodes.txt mods.

- Added "Survivor Swap", this Co-op Mutation swaps the survivor set for the 13 official Valve Campaigns.

- Added "The Witching Hour", 1 Witch spawns every second. Be careful, they're supernatural!

- Added "Left 4 Gun Game", you receive a random weapon every 10 seconds and normal map pick-ups have been removed.

- Added "Left 4 Gun Game: Special Edition", same as above but with a twist of Special Delivery.

- Added "Immoral Support", the Special Infected can't be killed with bullets, you have to use Vomit Jars collected by dead CEDA agents to kill them. Common Infected don't do

much damage to survivors. But beware, a Boomer's bile attracts Tanks!

- Added "Call of Boomer", similar to Deadly Alliance except there's nothing but CEDA agents, but not all will have Vomit Jars. Only Boomers spawn who attract Tanks with their

bile.

- Added "VIP Escort" (WIP) Co-op Mutation, 1 Survivor is randomly chosen to be the VIP who only has half health, but regenerates health over time. If the VIP dies, everyone

dies!

- Updated "United We Stand", the L4D1 survivors now spawn in better locations to assist the L4D2 survivors in surviving.

- Updated "Plague of the Dead", changed a few minor settings and added some new HUD elements to detail who has been infected.

- Updated the "Death Clock" Mutations, added a timer on the HUD to show how long you have left to live.

- A few minor edits to other Mutations.

The changes include the following:

- Added "Plague of the Dead", only Commons that require headshots to kill. If you get incapacitated you have two minutes to live until death by infection.

- Added "The Real Zombusters", Realism mode with the HUD completely removed, with only Commons that require headshots to kill. They will incap you in one hit, and you only have four incaps until death.

- Added "Bombing Run", only Pipe Bombs against SI and Commons with the detonation timer reduced to 1 second.

- Added "VIP Target", a Versus Mutation similar to Last Gnome on Earth.

- Removed "Brainshot!", it has been replaced by "Plage of the Dead" and "The Real Zombusters".

- Updated "Random", added more types of SI combinations to the randomizer.

- Updated "Tank Attack", there's still infinite ammo but you now have to reload your weapons.

- Updated "Tank Assault", more Tanks spawn at shorter intervals.

- Updated "Tank Attack", "Tank Bake" and "Tank Assault", Tanks now die instantly without going into death throes.

- Updated "Classic Campaign", "Classic Survival" and "Classic Versus". The skybox used is now independent and no longer conflicts with other skybox mods.

The changes include the following:

- Initial upload to the Steam Workshop.

- Added "Random Mutation", this Mutation randomizes a few elements resulting in different types of play. (Testing, feedback welcome)

- Added "Brainshot!", a headshot only Mutation with only Pistols and Magnums, and the Common Infected incap you in one hit. The survivors have infinite incaps, so stay together! (Testing, feedback welcome)

- Added "Realism Gib Fest", Gib Fest for Realism mode.

- Added "Classic Darkness Falls", created by ==Maverick==.

- Removed the 'Search For Games' Flyout and added the 'Server Browser' to the Extras menu.
