The Foundry is a 2nd level variation, the other being the Gearworks .
Low. Relatively low spawn rates of turrets and bots. Expect new turrets to appear that were not present in the Foyer.
The largest threat in the Foundry is the environment. All rooms contain either lava pits or rotating spike rings (around the edges).
The Foundry consists of the spawn, three rooms, and the boss room.
As befits a foundry, everything is awash in a red glow. The walls and flooring have a dark red color, as if it was washed by lava.
- No spoilers, but many secrets are contained within the lava.
