Hey guys and gals! Here is my 100% Achievement guide and full walkthrough for Infliction!
This is for collecting two certain collectibles in the hallway.
One is medicine in the white hallway (leading to kitchen) on the right hand side.
The other is a camera amongst beer cans on the left hand side just as you exit the living room.
Go from 14:15 in my video to see where to get these 2 collectibles and subsequent Achievement.
Hope this helps!
