Two square open rooms (small), joined by an open doorway. More weapons than the Marines used in Granada. No cover, no secrets... just stand-up-and-shoot-the-guy-next-to-you carnage. Update changes walls from huge floor-to-ceiling windows to white with tiny windows. Also includes several films.

One large arena with several perpetual baddies, and lots of fake walls hiding passageways. Look for misaligned textures when you can't get out of a room.
