Achievements that do not require too much effort to be obtained.

Party with other players


Easy achievement, simply join a group once you're invited. Or, create a group yourself. Click the second button on the top left of your screen, you can invite a maximum of 3 players. Group is a great way to not lose track of your friends in case you are playing together.

Reach level 10


You'll eventually reach level 10 by completing story-related quests. Early in the game the reward is mostly 5.000 XP, so it becomes easy to level up.

Rescue another player 20 times


According with the achievement description, you need to rescue 20 players that died, however, I got the achievement rescuing only 2 players. If you see a player stunned with stars rotating around their head, click them and wait for the bar to be filled.

Trigger an elemental combo 30 times


Elemental combos are activated by elements (fire, toxic, flammable, electric, cold). It counts each time you do a combo using one of them. It can be activated throwing a gas bottle or using a toxic mine for example. You will probably get this achievement without even noticing. Battle and weapons kits can help.

Reach level 30


This one might take a while but you will eventually get there. If you want to speed up the process, you can threat farm by killing the biggest number of zombies as you can. Completing the story quests, adventures and daily quests also help due to some of them offering xp as reward.

Craft 30 items


To get this achievement, you will need to build an assembling table and the crafting table on your camp first. With both those building, you'll be able to craft items, weapons and get the achievement. But also, you'll need resources to craft.

Achievements that require some sort of strategy or that will take a bit longer to get.

Equip a protection kit


Protection kits can be equipped to a certain type of clothing, giving you some sort of buff. You simply need to drag a protection kit into a free slot. However, to open a slot, you'll need to upgrade the clothing. You'll need Fabric, and Sewing kits to do that. Fabric can be obtained by salvaging items (Panda push, Mop, Bandage, Golf flag, Torch, Doll, ... and many others.) Sewing kits can be obtained by completing all sorts of quests, adventures or by opening a chest on a secret passage.

Complete 10 Adventures or Expeditions


To get this achievement, you'll need to complete 10 adventures (expeditions are not avaliable yet). To start a adventure, go to Lakeville and search for the table. Click to join adventure (the dificulty can be normal) and wait for 3 more players to join (look at the top middle of your screen). After the adventure is done, repeat the process 9 more times :)

Complete 5 adventures or expeditions in maximum difficulty


Do the same process above, but this time, you'll need to choose the highest difficulty (Survivor) before you join the adventure. Survivor adventures were easier in the past and you could get this achievement easily. But it has been patched and now it's harder than ever. Be careful to not die, since all of the strategies will be activated while you are on the adventure. Good luck!

Discover a treasure among an infected horde


To get this achievement, you will have to open the chest in a secret passage 30 times. Keep an eye on the /chat sp because players usually announce open secret passages there, so more players come decreasing your chance of dying there. Socialize more, make friends, join a tribe and make it easier for you to get into secret passages. You can check how many times you already opened a chest by checking your profile. It doesn't need to be exactly 30 diferent secret passage locations, you can open the chest on the same secret passage 30 times, but there must be a interval of at least one day otherwise it will not count.

Kill 20 infected Peruvians


Excluding the world bosses, the Peruvian is the infected with the highest number of health. If you are solo, it will take you some time and strategy to kill him. Peruvian is also one of the rarest zombies, there's only one of them spawning in each zone at a time. It is easily found at the desert. Careful, it can kill you with 2 or 3 hits. Attacking him in group is a great idea, usually if nearby players see you attacking him they will attack as well since the Peruvian drops good loot.

Complete 30 daily missions


To view your current avaliable daily missions (or daily quests as they call it), click the star icon at the top left of your screen, it is the seventh icon. The reward for the completion is very similar to the level up, where you have the opportunity to choose between 3 rewards. Daily missions reset each 24 hours. Completing 30 of them isn't hard, but it will take you at least 10 days.

Reach maximum quality for each type of clothing gear


Follow the instructions given for the Armored achievement. You need to upgrade until you reach exceptional quality on all your clothing parts. Shirt, pants and shoes isn't enough, you need to get a hat too.

Find a roommate


In order to get this achievement, you need to build a Goat pen or Chicken coop for your camp. You can get the Goat pen from the Research workshop, and the Chicken coop costs 1000 wood to build, so it's probably going to take a while to get this achievement.

Build 30 buildings


Here's a list of the camp buildings:

Achievements that are not easy to obtain. Do not expect to get these any soon.

Reach level 5 Threat


If you plan on getting this achievement solo, you better bring a whole arsenal because you're gonna spend hours killing zombies. A quicker way is in group with your friends, or with your tribe. You need to kill zombies until the purple XP bar at the bottom of your screen reaches level 5 (3500 XP).

Kill 5 infected only with the explosion of an unstable infected


This achievement is not as hard as it seems, but it might take you many tries before you can make it. Find a gas bottle and throw it on a group of infecteds, make sure there's a unstable infected in between. Gas bottles can be easily found at the Purge the Filth adventures, or at gas stations. Now throw the bottle, the damage will be enough to kill the unstable and also damage the zombies around, granting you the achievement.

Reach level 100


Long journey ahead. Probably the last achievement you will get. Lots of grinding, farming threat levels, thousands of kills, deaths, secret passages, quests and missions. Good luck, you'll need.
