A small, bug-hunt-like level. There's an outer ring into which everyone must enter from their starting points. Inside that, there are a few small rooms with lots of cover... even though it's not large, you can stay alive a long time if you play it right. (Not much open space.) Inspired by the colony of the same name in Aliens.

A striking map, designed for king of the hill. You want to stay on the high ground, because there's a switch that will flood most of the map in lava... The hill is quite reachable from this switch, so beware the cherry picker. (The lava's supposed to drain if you leave the switch, but I found with a little fancy footwork, you could make it to the hill with the lava in place... it'll go off when they die and regenerate, but this is a cheap way to get a few extra seconds of hill time.)

Thunderdome, slightly modified and with a nasty physics model. The elevators go all the way up now, but the ledge side never got textured, which makes for some trippy views if you're looking out at the arena... There are aliens now, and the physics model makes 'em really nasty. Supposed to be a training level.

Another type of capture the flag. Find the switch in your opponent's base, then come back and flip your own. Your opponent's base will fill with lava. (Likewise, if he gets to yours first, upon flipping his, your base will fill with lava... should make you think twice before flipping...)
