Alex First
Two maps. One (Caverns) is dark, twisty, and has lots of explodabobs and MoaHs. Its main point of interest, though, is its creator... Alex Okita is an artist at Bungie West, working on Oni. This was his first Forge map. (The other map in the archive was made by a friend of his, and is a model of the friend's house. Lots of weapons, but in very specific places... take a runthrough before you play this one.)
