Two maps (well, there are three, but the first and the third are identical) with some very interesting physics experiments. The first map has a very useful jetpack built into the second trigger of every weapon. One of the best I've used. The second has some pretty serious weapons modifications... as a solo test level, this one'll keep you coming back for more, and as a net level... well, carnage rates will be pretty absurd. Nicely done, as experiments go. Give 'em a try!

6 levels, three previous releases with tweaks, three new. Mostly geometric layouts, but they work pretty well. Lots and lots of baddies, so solo works fine, lots of physics tweaks ...

Geometrical, few visual cues as to where you are. Constantly regenerating baddies give you something to shoot at if you have no net connection, but a plethora of invincibility powerups make them rather impotent. Don't fall in the water... you get transported to a room with no escape, and the only way out is to sucide under a crusher.

A slick little rotating space station (contains a shapes patch to produce the rotation... don't worry, it's small). Big weapons are upstairs. (If you miss the elevators, check your map view.) And watch your back... the compilers outside can nail you if you're not looking! Might be big for 2, but should be okay for anything larger.
