The goal of the modification is to blend together elements of Doom, Doom II, and Doom 3 together into an "LMS Mod" gametype, and also to provide cooperative play for the single-player campaigns of Doom 3 and Resurrection of Evil.
Cooperative support for the Classic Doom 3 modification was implemented in version 3.0 (23 February 2006).
There are three distinct map types present in the gametype "LMS Mod":
- KF (Killfest). The basic goal is to kill as many monsters as possible and remain the last marine (player) standing at the end of a match.
- Prog (Progression). Players progress through custom-made levels much like in Doom 3 single player levels.
- Def (Defense). Players are forced to hold off a certain area, protect a VIP, and/or progress backwards, holding off an invasion force of monsters until a timer runs out or an objective is completed.
- Infrared view, which is only available in the "LMS Mod" gametype, enables players to see monsters much more clearly than in normal view.
- Additional weapons, only available in the "LMS Mod" gametype, include a double-barrelled shotgun reminiscent of Doom II 's (not the same as the one included in the Doom 3: Resurrection of Evil expansion pack), a plasma-based flamethrower, and a "Plasma Sniper" weapon. A wrench, bearing many similarities to the flashlight, replaces the fists.
- Soundtrack that features several heavy metal songs. Musicians and bands featured include Skaven, Naxiel, Neurosphere, and Switchblade Masquerade.
Last Man Standing includes several new monsters, most of which are modified versions of Doom 3 monsters:
- Dumbfire Revenant
