The first two levels of a rather large scenario. (All the levels are there, but only the first two have polygons in them... well, the third has a pair so that you can teleport in, but...) Generally pretty difficult, but more for techical reasons than anything else. The central shaft on the first level (by which most intra-level travel occurs) is a bit tough to get the hang of. Once you've figured it out (and ignored the bad textures inside), it's pretty cool... and there's a nice trap on level two.

Interconnected passageways and a small pool with goodies in it. The door controls introduce some nice flow oddities. Comes with a physics model that allows bullets and grenades to penetrate water.

10 maps, ranging from quite good to downright annoying. The first several have heavy emphasis on water. The last few are unplayable-we were getting framerates of less than 4/sec on ethernetted powermacs. With fewer aliens, less ammo, and less open space, they might be okay...

Very dark arena, with a sniper ledge running around the top edge. Very nice flow-there are multiple ways to get to most spots.
