The Tycho Complex is divided into numerous sectors. Sector Seven -- Environment Processing -- houses air, water, and waste recycling and filtration facilities that service the rest of the Complex. Here, we pay a visit to the Water Treatment facility.

It's up to you and your friends to give the facility a fresh coat of red paint...
