Blizzard this week launched StarCraft II: Wings of Liberty, the long-in-development sequel to its popular 1998 real-time strategy game. The new title follows Jim Raynor, who has become a rebel leader trying to bring down the Dominion for crimes of genocide. While the original StarCraft had Terran, Protoss and Zerg campaigns, the sequel revolves mostly around the Terrans in a 29-mission single-player mode. A few side missions give players a taste for Protoss units.
