The treatment pool is a vat where fluid from the rest of the complex was collected, purified and drained back out. In the
Industrial Zone's current state, it's a circular pool of gunge several metres across, which is usually prepared as a mixture of green and red slime with a layer of foam on top.
In this room, players are usually tasked with dipping into the gungy vat and finding a set of items resting on the bottom of the pool - for example, a set of electronic cubes that will open a door they need to get through. Points are awarded by how quickly they complete the task. Alternatively, up to two seats can be connected to the upright girders behind the vat, so a player can be seated above the pool and dropped in on completion or failure of a different game.
