Physics Testing Grounds v1.0

This is a map that I made about four years ago that I used to test physics. It is a series of doors and swithces that release monsters into an arena to see how they interact from the safty of a monster-proof control center.

you can also go into the armory and shoot them if your bored. As an added bonus you can use it to teach your friends how to play marathon.
