Then, he goes on a 1 Minute cooldown and will give you another charge when available. After getting three charges from the same technician the achievement will pop in. It might be important to note that If you are spamming E it will cancel his charge animation.

Aim to the red camera.

I have a problem with The Might makes right achievement, No matter how many times I hit the robot with the crowbar or wrench, whether it's friendly or enemy, it doesn't die. I tried it on easy mode and fought them on hard mode too, but it seems that melee attacks don't hurt them.
What am I doing wrong?
DerpyDoo 21 Jul @ 9:17am 
I can't seem to find the "Oops nothing personal" crate, I've replayed the game a few times now and have not come across a screaming scientist or a yellow keycard

BottleCap 11 May @ 4:33pm 
Jewelry work is bugged? i already killed a bunch of zombies headcrabs with the wrench and i still dont have the achievement

Good guide!
As a tip, you should move "Helpful storage room" achivement to the top, or at least mark the rooms in order of appearance thoughout the guide. I wish I'd know that the first time, haha. :gordon::bms_crowbar:
Khodyrov 29 Mar @ 2:59pm 
For "Oops, nothing personal" maybe add a screenshot where the door is closed and behind it red barrels, i spent more than an hour backtracking until i found it using noclip
Khodyrov 28 Mar @ 5:47pm 
For "Might makes right" i just keep hitting until he push me and start shooting at me, doesnt work as described
