This puppy's BIG. Also dark, with winding, twisting passages, and many many levels on top of each other. And bright, with open, airy areas with nice views. (Did I mention it was big?) Don't bother using your map... it's nearly useless. Engrossing, but watch the traps-you'll have to start from your last save if you get caught... Update fixes a few things that are funny, adds baddies, aligns textures... It's also not bright anymore. (It's at night.)
A fun romp through a bunch of rooms... a couple of secret ammo dumps to find, and basically just a lot of carnage to keep you busy for a while. Update adds a couple of terms, courtesy of Hex!
