From Halopedia, the Halo wiki
Template:Multiplayer Map Infobox
Derelict is a multiplayer map in Halo: Combat Evolved. It is set aboard a Neutral artifact, catalogued by the UNSC as Deep-Space Anomaly #0198. It is a very small level that is best suited for 10 or less players, as more can become extremely chaotic, unless that is the desired effect.
On April 17, 2007 it was released as Desolation for the Xbox version of Halo 2 in the Blastacular Pack.
