Dead Maze

Once you get the research table, one of the random possible projects you will see are the goat house or the chicken coop.

You will get a new research project daily with the possibility to reset and renew one of them to see if you get something you want, daily too.

Building any of these will give you the achievement, prepare to expend hundreds and hundreds of resources, specially wood.

Threat level accumulates as you kill infected or get XP items from their corpses.

The trick here is that threat disappears as soon as you rest in a spawn campfire or use a campfire of your own.

So here is what to do to get rest, food and water points back.

You need to find a unlit campfire and have something to start a fire. Matches, molotovs, firestarter kits, etc.

The crucial point in using these campfires is to NEVER feed them with tools, wood or stuff, feeding a fire will reset your threat level.

Eating or Drinking costs about 10 rest points and lighting a campfire gives you back 50, so eat and drink outside the campfire interface and use your fire starting stuff to gain the rest points back.

It takes around 200 infected to reach level 5, more or less.

This is easy with a molotov or formula X grenade weapon and a gun.

Find a group of infected with the Unstable, throw the grenade and then when their lives are about 30%, shoot the unstable from a distance.

If you get close, you might swing and hit one of the infected that you want the unstable to kill.

Now, remember that you dont need to kill the five infected at once with the explosion, even if you kill one or two is fine, you can repeat this until the achievement unlocks.
