|If you're searching for the Unreal Tournament 3 map, you might want to check DM-DarkMatch.|
DarkMatch is an alternate version of the Deathmatch found in Unreal. The idea that makes DarkMatch unique is its maps, as they are all in darkness. The players are all equipped with SearchLights, to give players limited sight.
Unreal only included one DarkMatch map, DKNightOp. Later, many unofficial DarkMatch maps were released. All other rules are identical to Deathmatch.
