A pretty mazelike wheel, with what looks to be a truly deadly hill... check out the lava paths, it's worth your while.

Bungie's level, hacked down to playable net size. Still pretty big... my guess is 4 would feel lonely.

Again, Bungie's level cut down to net-playable size. Lots of nooks and crannies... just like the original. Only this time, it's your friends you need to worry about, not hunters...

A very subtle use of 5D (it's pretty easy to miss that you're actually in it). A small central pit with tiered hallways around it... the good stuff's pretty exposed, so be careful.
