Derelict

Derelict is a multiplayer map in Halo 1. 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 Halo 2.
