Desolation

Tombstone along with Desolation are upcoming maps for Halo 2. They are remakes of Hang 'Em High and Derelict.

Desolation has an entirely new setting. Rather than a facility of some kind in deep space, as Derelict was, it appears that Desolation is located on Delta Halo. The architecture appears to be of Forerunner origin and looks similar to the structures seen on Delta Halo in Campaign.

It may feature a similar weapon set to its precursor, but adjusted to account for Halo 2's different arsenal. For example, the Assault Rifle spawn may be replaced by a Battle Rifle or maybe even an SMG.

Desolation also has certain structural differences between itself and Derelict. The teleporters have been replaced by grav lifts that propel players from the ground to upper level. Also, the tunnels on the upper level have been replaced by ramps that lead down the the ground level.
