Unreal II: Expanded Multiplayer (often shortened to 'XMP') was released by Legend Entertainment in 2003. This free add-on for Unreal II: The Awakening combined hardcore first-person shooter gameplay with elements of vehicular combat, resource management and strategic placement of automated defenses. A strong community quickly grew around this title, with many even creating custom levels and other content for the game, however the life of this promising title was cut short with the closure of Legend Entertainment by Atari in January 2004.

Free Monkey Interactive has created UTXMP (Unreal Tournament Expanded Multiplayer), a total conversion for Epic Games' Unreal Tournament 2004. UTXMP offers intense class-based vehicular action in thirteen stunning alien worlds, where players must manage energy reserves to power their war machines and battle for the control of four mysterious artifacts. UTXMP players command an arsenal of deadly and sophisticated weaponry, as well as deployable automatic defenses and mines.
