The map environment is set in a futuristic silo, transformed for deathmatch play. 'The map looks and sounds like a real place, and plays differently to traditional killboxes'.

Many hours have been spent developing a deathmatch map that looks more realistic and detailed than maps of old. NextGen features new HD textures courtesy of texture artist Philip K, who provides free not-for-profit textures. NextGen moves away from traditional square killboxes and introduces a multi-environment arena, based on cylindrical shape and transitioning-platform, which transforms the environment at the flick of a switch. NextGen returns with the traditional lift platforms seen in killboxes, and uses water to add an extra element to the gameplay.
