Covert Operations

About

Covert Operations (sometimes shortened to Covert Ops) is a tactical military Doom II total conversion created by Black Shadow Software that requires the source port EDGE and reuses many resources in 1998's Twilight Warrior made by the same team. Covert Ops abandons DeHackEd patches and instead uses DDF to create custom enemies and re-loadable weapons. The WAD was an early showcase of EDGE features including 3D floors, colored lighting, translucent deep water, falling snow, and RTS action triggers.
