Four maps, none of them really playable. They're mostly idea maps... sort of trying out new architectures. A couple would make nice additions to existing maps...
A bunch of bobs, and a bunch of aliens... the only weapon is a single spanker. The readme says wait until you have it to start killing bobs... but when I did that, there weren't any bobs left.
A large arena, with lots of running room. There are also several narrow passageways around the outside, which provide access to sniper positions... The jug and the MADD keep things interesting for solo play. Size comes from an included sound clip.
Two maps. Party is 4 big rooms, LIve at London is a ring with sniper ledges and a central recharge area. Weird smearing because of a no-thickness wall...
A full set of textures (and scenery, and the Borg Cube) from Star Trek. You can see a good representation by patching your Shapes file, and playing Arrival (the first Bungie level) with these shapes...
