I'd really like to make a small hole in the back of foundation, room 1. In the back of room one, there is a wall, and then another room, and i wanted to make a little hole there so i can crouch and get back there. is there any way this can be done? it sounds like it might be kinda hard, but any help would be appreciated.

you could edit the bsp and take off the collision from there. Im not sure how to do it. there is a collision editor for the bsp around here somewhere.
