Amazing. 4 and a half years after the release of the original Marathon, maps are still being made for that engine. This is a small map that crosses parts of Mars Needs Women and Carnage Palace Deeluxe. Flow is quite good, and the map is familiar enough (yet different) to those who played Marathon in the early days that getting around is second nature. Definitely worth a look!

A large, square arena with a bridgelike structure in the center (over a lava pool). Most action takes place on the ledge around the outside, or down on the floor. Elevators are nice and fast... mix of open and closed spaces. Archive size is due to a number of screenshots. Map is unmerged, on purpose.
