A large honeycomb map. This one's designed for teams... the ammo caches require two people to access. (Check your map view for clues...)

Three levels: two Bungie M1 maps, and one original. All three are really, really fun. (Smells like Napalm is a blast-watch yourself on those recharging platforms!)

A pit, filled with many pillars which can either act as cover or induce suicides, is surrounded by a ledge. The pillars effectively hinder sniping from the ledge... but the high ground is useful, nonetheless. (Watch for shots from below, though... the ledge is lit, and the pit is not.) Teleporters bring you up, jumping brings you down.

A tall cylinder, with stairs (and teleporters) around the outside, and a very slow-moving platform in the center. If you can stay alive on the platform until it reaches the top (unlikely, but...), invincibility awaits you. (There aren't any fusion pistols...)
