StarCraft II: Nova Covert Ops is a downloadable single-player campaign expansion for StarCraft II, released in 2016 for PC and Mac. Developed by Blizzard Entertainment, it spans nine missions divided across three mission packs, all centered on Nova Terra, the Terran Dominion's most formidable Ghost — a psionic assassin whose disappearance coincides with a broader crisis gripping the Dominion. Emperor Valerian is struggling to contain renewed zerg aggression, and a civilian militia called the Defenders of Man has emerged amid the unrest, claiming to protect humanity. Players control Nova across a range of covert real-time strategy missions, including base infiltrations, interceptions of planetary invasions, and operations aboard experimental stealth vessels. The campaign sits within the broader StarCraft II real-time strategy framework while placing emphasis on the secretive, high-stakes world of Dominion black ops rather than the large-scale army management typical of the main campaigns.
