Ground Control: Dark Conspiracy

Ground Control: Dark Conspiracy is an expansion pack to the real-time tactics video game Ground Control released in 2000, developed by Massive Entertainment and High Voltage Software, and published by Sierra Studios. The expansion pack was included free for new purchases of the original game; existing owners were also entitled and merely needed to apply via online form, and was also included as a hard copy in specially-marked boxes.

The largest additions are a new faction, the Phoenix Mercenaries, and a 15-mission single-player campaign that expands on the original storyline. Other changes include extra multiplayer maps, a few more units for the existing factions and more terrain types. Also of note are the changes in the full motion video cutscenes; the parent game had all of its pre-rendered in the game engine. In contrast, the expansion's cutscenes were done by Blur Studio.
