This mod is set in Games Workshop's, great Warhammer 40,000 ( 40k ) universe. Each map pits Imperial Space Marines against the Tyranid swarm and the Legions of Chaos, competing in a series of mission objectives, culminating in a battle to decide the fate of the planet.

This shot shows the chaos held area of a new version of city conflict (one of the oldest maps in EX).
Back in 2006 when the only Source mapping tools were released for CS:S Dark Marine contributed a Source version of his popular City Conflict map from Rival Species (the Half-Life mod that was Exterminatus predecessor). The original goldsource version of that map had featured chaos fighting the loyalists in an imperial city.
Finally some twelve years later Chaos are back on City Conflict.
