Entropy Zero 2: 100% Achievements Guide

Never had it anyway.
Play prologue until the very end, unlocking the only achievement in the chapter

Cell Division
Reach the extraction point with four soldiers.
Find and add soldier(s) to your squad. They must be alive at all
A soldier being melee-killed by an antlion worker is scripted and thus doesn’t count toward achievement
You can call your squad to wait at a safe place so antlions won’t damage/kill them
This task starts when you meet the first soldier (left screenshot) and ends when you reach the shotgunner guy (right screenshot)

New body. New Boots.
Unlocks after destroying the antlion holes and getting into the container in the last area

Interdependency
Get health from a surrendered medic.
To make a medic surrender, you must disarm the weapon they wield and while fleeing or about to picking up a weapon, press E on them. Your HP must be below 100 or else they will not heal you
Make sure medics are at a safe place as they can be killed by a rebel grenade or gunfire
Kicking is also very useful to not accidentally kill
You can recognize medics by their armbands and backpacks (screenshot)
Can be done on Chapter 2 or later

Please Knock
Kick open 60 doors.
Press V to kick open doors. The game has over 60 doors so it’s possible in a single playthrough
If some enemy has opened the door, you can close it and then kick it, this will count
You can farm this achievement by saving, kicking, then loading. Repeat until it unlocksScience Team

Visitor Pass/Bootstrap Program/Mirage Clearance
Earn bronze/silver/gold medals on all challenge maps.
There are 8 maps with 5 types of challenges, in which you have to complete all 40 challenges
Challenge description:

• Least Damage
  One of the two difficult challenges, for that, you must not take at least damage at all. Thankfully, quicksaves still heal your pain
  Teammates being hurt doesn’t count, so feel free to use them as meatshields
• Least Bullets
  You must spend at least bullets that’s under the goal, just rush to the end and pray that rebels won’t manage to damage you
  Kicking is very useful for disarming weapons and you can use that to beat up rebels to death
  Let your teammates do that as their bullets don’t count
  Explosives and projectiles such as crossbow bolts do not count as bullets
• Least Time
  You must race to the end while killing any enemy that is blocking your path
  Don’t forget to pick up any items to heal your HP and conserve ammo
• Least Kills
  Well that’s one of the two difficult challenges because plenty of enemies in a map
  Once again, let your teammates do that as their kills don’t count
• Most Mass
  Simple, use Xen grenades to consume much things. Ammo is limited, use them wisely
  Objects and items won’t be enough to get a gold medal without enemies on some levels
  Make sure how much things are in a grenade radius

Alternatively…you can cheat out challenges by typing “sv_cheats 1; god; sv_cheats 0” into the console without quotes. You’ll just ruin your experience however
Once the last gold medal is obtained, you will get the “Mirage Clearance” achievement for your hard work (or little effort if you cheated)
