A small arena with a sewage-filled pit in the center (hence the name), but most of the action seems to congregate in the side passages, where the weapons are... Drop back into the pit for ammo and a recharge canister. Keep an eye out for secret passages...

Original version released in No Parole. This is a multi-level arena, with extremely fast-moving elevators bringing players to all levels. There's a small danger of non-regeneration due to the near-constant motion of the elevators, but otherwise, this is a really fast-paced level with plenty of weapons. Two versions-one with baddies, one without. Update adds new sounds, tweaks object placement.

A short (okay, very short) but entertaining solo level, where you're a security officer on a cruise ship with a very proper AI. It won't take you long, but the terms are funny.

A larger, rambling level. You start on an outer, elevated ring, that cannot be returned to without some judicious SPNKer jumping. On the main floor, lots of constructs break up the line of fire, and provide hiding places... but secret doors and teleporters give access to all parts of the map very quickly, so there isn't much safety. Playable with two people (a little slow), but really comes into its own with 4 or more. Comes in two versions-with and without baddies. Update adds a third version of the map, this time with H-Bomb explosions to add to the ambience.
