A multilevel arena. The textures keep you from getting your bearings for a little while... and your opponents will keep you from it for as long as you play. Very open, with lots of ways to get from point a to point b. Always check above you...
A small, tall room with stairs around the outside, a couple of protected rooms with big weapons (and teleporters as the only entrance), and sniper pillars. Vertical distance is big enough that you actually have to aim.
A two player map. Each player is in an enclosed space, facing the other across a no-mans land. Death rates will be low, unless your opponent doesn't know how to take cover.
A circular main arena, with a passageway circling it at ground level, and another on the second floor. Sniper ledges with lots of cover are also on the second floor. There are two additional versions of the map included, for smaller groups-one removes the ground floor outer passage, and one removes the second floor outer passage.
A straightforward carnage arena. Two pillars in the center, a sewage-filled passageway around the outside, and some outside ledges. There seem to be some bad walls (poly edges with actual textures assigned, even though it's supposed to be open space), but I didn't get any crashes because of it...
A modification of FrigidMan's Axiocranium (authorized). New secrets, many more baddies, and some really, really death-dealing physics. (Do NOT, under any circumstances, be holding the fusion pistol when it overloads.)
A pretty nice little arena, with lots of side passages, and WAY too many hunters. I guess if you were into practicing against them... Don't get trapped in the bob generation room.
7 maps. A few are ports of the M1 version of Lost Angles (I think). Others seem to be new. Generally decent layout, a little bit sloppy (lots of bad textures, misaligned textures, that sort of thing), but good play.
Four maps. Two are straightforward arenas, but the other two have some unique features... See how long you can stay on the hill on Piston (sniper points are placed particularly well), and InnerSpace is pretty cool.
An arena with a sort of a spiral staircase looping around and above it. Lots of wall openings, but once you're past the first ring, you're pretty much out of range unless your opponent is REALLY slow.
Imagine Everyone's Mortal But Me with deadly sniper seats... A grenade from the hill into any sniper seat will make life very uncomfortable for anyone in there, whether the grenade hits near them or not. A pretty fun secret that will never be seen by folks not using custom physics models (like the one enclosed).
Simple in design, but pretty fun in netplay. Four staircases meet in a cross, with the hill at the top. Around the bottom is another ring, with ammo... but you actually have to be coming up the stairs to get a shot at anyone at the top. Watch the walls when wielding that spanker...
