Geometrical battlefield (designed for teams, but playable without them). Has an invisible wall bug that makes it impossible to get to one of the chargers. (I was unable to fix it.) Author says it's unfinished. (Still plays okay, except for the wall bug...)

A city scene. Pretty well done. Nice recharger placement.

Very symmetrical, very green, all travel goes one way. Nice weapons placement.

A very simple vacuum level, requiring the enclosed flying physics model. Careful about landing!
