For anyone who ever played the M1 map Aim High, you'll recognize the feel of this map-enclosed catwalks above tall platforms and a lava-threaded base. For any who haven't, you'll find this map requires real up-and-down aiming abilities... and the skill to recover from weapon recoil. Far easier to look at in hi-res than low.

A tall central arena, with catwalks leading to the hill. These can be lowered with switches on the hill, but they're also player-triggered... so you're not particularly safe there. Passageways around the outside contain weapons and ammo... and small hopscotch courses through lava pools (easy to do when you're concentrating, a bit harder with someone shooting at you).

A pretty cool arena level. A port (with major changes) of the M2 map. This might be best played in teams... there's a large central arena, with a pit in the center. Lots of big weapons there, but switches on the outside rim lowers the pit and dumps the trapped player in small crusher cells. Escape is possible, but the door is slow... which is why tag teams would be nice. I

Five levels, some ported from M2 suicides, some brand new. All quite playable (except maybe Kevorkian's Rooms, which will give you a horrible headache). Deadly Ledges is very nice for extremely high-carnage games.
