Nassau Station is an unlockable stage from Dead or Alive 4. The stage is actually the Cairo Station from Halo 2. This stage is encased in a dimensional distortion off into the future where SPARTAN-458 awaits a challenger.
When SPARTAN appears in Time Attack, she laser-slices a twin door where she smashes it open, warning her "intruder" to leave.
The stage has two levels, where one would start on the higher ground on the catwalk platform. When a character falls off they may fall onto a Warthog, depending on their fall location. Many things like a Warthog, Covenant shield generators, and controls are at the ground level. Knocking them can give extra damages.
