The Sink continued to ruthlessly scrub any particulate matter that came near it. Once it learned of the Innovative Toxins Plant, however, it gained new purpose. It sought to develop anti-toxins to flush into its drains and counteract the poisons bleeding into the soil.Old World Blues ending slide

The Z-43 innovative toxins plant is a location in Big MT in 2281. It is located northwest of the Saturnite alloy research facility, west of the X-12 research center and east of the X-66 Hexcrete archipelago.


Radiation is present throughout the facility as well as the outer entrance. The building consists of three main areas: the entrance, a large main room, and a small room opposite the entrance. There is also a catwalk above the main room. In the small room on the ground floor, there is a footlocker as well as a chemistry set that can make chems with a Science skill of 25.

Behind the scenes

When entering the facility for the first time, several Y-17 trauma harnesses will attack. With the Wild Wasteland trait, one of them will say, "Hey, who turned out the lights?" This is a reference to the Doctor Who episodes "Silence in the Library" and "Forest of the Dead."
