Three more, all originals. These are reminiscent of the early M1 suicides... high carnage, no hiding places, lots of in-your-face action. Storm Drain is beautiful, both for action and for looks!

Infinity remakes of some classic M1 levels... these bring back memories. (I even remembered where the flamethrower was on KillKillKill!) In general, these are much brighter than the originals... this may disappoint you if you like to lurk in shadows (which all three of these maps were good for). Two versions of Billy... one with media and one without.

A mazelike level, with the hill in the center. Once you're on it, you'll be there until you die... and once you run out of ammo, you won't be able to defend yourself. Each section has a route to the hill. A little claustrophobic- the ceilings aren't very high (usually).

Large (frighteningly large), and it uses exactly one texture. Designed to look like a rabbit warren. It does. I say leave it to the rabbits.

A multi-tiered arena, with the hill at the bottom. Small rooms around the outside of the middle level provide breathing space (although the pulsating walls are a little annoying). Trapped exploda-fusion-bobs provide static entertainment.

The infinity level, ported to the M2 alien textures. It's no longer vacuum, and all the baddies are gone... but so are some of the windows (which makes for easy transfer from hallway to hallway, actually).

Simple outdoor maze, with a couple of rechargers and a (not-so) secret room. Flow is nice... but it could use some sounds.

A multi-tiered level based on the concept of a box canyon. There are no indications for the elevators... you just have to know where they are. Seemed really, really low on ammo, as well...

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.
