File:E3M3 - the Tomb of Terror (Deathmatch)

Description
Various traps make this level rough to navigate in Singleplayer. In Deathmatch, I can't imagine this being very practical, especially when many corridors are tight and allow for easy Rocket Launcher kills. Once again, this is what happens when you make something intended for Singleplayer into a Deathmatch level!
