LMSAssault is a gametype modification for Unreal Tournament. It extends the gameplay of Assault to incorporate features of Last Man Standing. Each combatant has a fixed number of lives, and when these are gone, that combatant does not respawn, and must wait until the game is complete (Human players do respawn, but as spectators).

LMSAssault is based on LastAssault, a similar mod by Kevin 'Zaph' Burfitt, but adds full configuration features. The default number of lives for both attackers and defenders can be set, and can be over-ridden on a map-by-map basis using the LMSAssault.ini file within UnrealTournamentSystem.
