Amnesia: The Dark Descent Walkthrough: Chancel (1)

Move up the stairs and continue on. Open the door and enter the room. Wow,
bright bluegreen lights and… YIKES!!! A bunch of monsters! It’s an
ambush!!!

Don’t worry, this is actually part of the storyline. We’re supposed to be
ambushed by monsters at this part. After getting knocked out, we got thrown
into a cell. I guess those monsters have some sort of intelligence after
all.
