with a map this small, you can go into great detail, and try to get things as accurate as possible.

part of what would make it more accurate would be a higher ceiling. it's just way too low, in comparison to the movie. i also remember there being a bit more hallway, but that might just be me.

the warp thing was a good idea, but it felt kinda wrong. you needed to have just made a really simple folder containing a supersimple white skybox (we're talking 16x16 images), and gun racks. i'd be happy to model them if you want me to, it souldn't take more than a few minutes on my part. if i put in guns that'd make things trickier and more sizable, but that's possible too.

also, the warps are way too close together (map on the grid, even for that) and there were come empty spots. i would have used at least some of that massive filled area or those empty rooms to make more warp areas, so there's less chance of a spawn overlap.
