The Storage Wing is a dimly-lit section of the base carved into the rock that the base was built on. The team find themselves in a set of corridors with stony walls with bare bulbs hanging from overhead wooden beams, with mysterious equipment altered to create messy challenges.

The Processing Wing is where materials were shipped from and received into the ocean base. Grey-blue and metallic, the area is based around a hangar with The Shuttle standing in its centre, with game rooms accessible from floor level and a gantry around the wall.

The undersea level is a dark, corroded area underneath the main facility - the Industrial Zone's muckiest games are down here, often using tanks of murkier slime that contrasts with the bright, smooth gunge in the other areas. Entrance is via a small hatch and stairs descending into the dark room with the Treatment Pool, or down a rusty lift into the room that houses the Sludgecube.
