The action takes place in a forgotten presidential bunker. We have pushed the engine to the limits by including 4 crossfire-like event and tons of interactive features (top-secret toaster switch, activation puzzles, actual numpads). This is one of the rare multiplayer map to use monsters, among other, for its scientist torturing booth! You can even unlock the surface if you dare take the death path.
I defy any of you to find a map with more features than that.
