DOOR 150, "The Prison"

As you would have entered Door 150, The Prison, you'd run into The Watcher, and just as it was about to kill you, Guiding Light would show up, using it's sword to stab The Watcher through the torso before being stabbed by The Watcher's hook and being stomped on and killed, after that you would have ran away from The Watcher and into the Security Room, the metal gate closing behind you as it banged on the gate, eventually leaving as the alarm's stopped, and it went around the prison looking for you, you'd pick up a tablet that would say that 5 lever's are required to be pulled for the code and for it to then be entered into the terminal next to you for the exit to open.

The Watcher would currently be going through the empty mess-hall of The Prison, looking around, it's just You, and It, no one, nothing else.

Growl

It would let out a Growl as it walked around, occasionally stopping to look around, due to it's large eye, this thing has some GOOD eyesight, so it can see you from like 10 room's away almost.
