Based on the original Arena in M1, but with much wider hallways. (And an extra secret or two...)

For anyone who's seen a previous incarnation of this map (it is available in both M1 and M2 flavors), this version is a serious upgrade. It feels more like a small city block, instead of a single room (well, a pair), and there is support for 8 players, finally. For those who haven't seen this map before, check it out. This is 5D space taken to the extreme. Two nearly identical areas (differing only in textures) occupying the same space, with windows for attacking, and a convoluted passageway to actually cross over. Spectacular...

An extremely fast-paced map, with a tiny open arena in the center, surrounded by eight entrances on two layers... and a rolling staircase around the whole shebang. Absolutely no place to hide...

Allows you to modify saved games to give yourself obscene amounts of health, ammo, oxygen... and it works on everything from Marathon 1 (all versions) through the M2 preview, the M2 demo, the M2 full release, the Infinity Demo, and the full version of Infinity.
