Hey guys and gals! Here is my 100% Achievement guide and full walkthrough for Infliction!
At the beginning of the game, you are outside and need to walk to the kitchen double doors to enter.
From the kitchen, go into the first door on your right.
This is the living room.
Simply interact with the remote on the Coffee Table to unlock this.
Or go to 3:10 in the video to see how and where it unlocks.
Hope this helps!
