Amnesia: The Bunker

This requires you to kill five rats with a single grenade.

The easiest spot that I found was inside the Arsenal area, near where you retrieve the Dynamite Bundle key item. In this area is one soldier body that has a dog tag. It’s hard to miss, you need to come across this to progress the story; it’s in Storage Area B per the game map.

For me, the body in here was being nibbled on by five rats. No need for meat or fancy tricks.

Another body with five rats is in the Soldiers’ Quarters, it’s Barracks A which is the room with all the bunk beds on the right hand side as you enter the area.

Be mindful that burning the corpses affects the rat spawns. Not a big deal since you can start a new game and unlock this quickly, but a point to note if you’re trying to optimise your time.

At one point in the game, you'll have to use the radio to receive a code to the Arsenal. Once you go in there, you'll have to avoid a few traps and use the code to enter the ammo depots to reach the explosives. In this room, there are about five rats munching on a corpse right beside a gas canister and an explosive barrel. As you can see in the video, I was out of ammo for the revolver, so I used a grenade to blow up the explosive barrel and, by accident, also popped this achievement.


Yeah, it says so in the description of the goddamn achievement.
