Get the key | Penal Colony - Claire RE: Revelations 2 Guide

The key is on the guard's body.

Approach the barrier by the hanging body and get the key ([E]). Unfortunately, it falls down. Take the door that has just opened, ahead of you.

In the drawers, there are stones, for which you are rewarded with additional CP.

Walk over to the other end of the corridor and take the only way to your left. At the end of it, you open a big door and enter the room covered with blood.

In the left corner of the room, in the desk, there is a Ruby (250 CP, open the drawer [E]). In the another desk (also in the drawer), there is a Sapphire (500 CP). You can now leave the room.

Search the corpse and Claire will find a gun.

Right past the door, take the ladder to get to a lower level. Approach the corpse of the guard to find the key - it is not there but, you find a pistol with 9 rounds.

First, use Moira's flashlight to find the key and shoot it down with Claire's gun.

Then, cut to Moira ([TAB]) and light the area a bit above the corpse, to locate the key. Then, cut back to Claire, aim ([RMB]) and shoot down ([LMB]) the hanging key. Pick up the Experiment Block Key.
