"Dark Sector" was based on the Sector Engine, later changed to the Evolution Engine, both Digital Extremes' proprietary game engines. Statements about this being just a name change or a major shift in their technology were not released to the public yet. "Dark Sector" project lead, Steve Sinclair, stated that the engine was written from scratch. The producer of "Dark Sector", Dave Kudirka said when they first built the engine, they did not want it to look like the Unreal Engine 3, and they wanted their own perspective engine. When asked about the games' engine being made on the Wii or PC, he replied "plausible". The game went gold on March 7, 2008. The musical score of the game was composed by Keith Power.
