StarCraft 2: Heart of the Swarm, the second salvo in Blizzard Entertainment's three-pronged sequel to the beloved RTS, has managed to entice 1.1 million gamers in its first 48 hours. The 1.1 million figure accounts for sales across both retail and digital.

Predecessor StarCraft 2: Wings of Liberty managed to sell 1.5 million copies worldwide in its first 48 hours. Both can't match Blizzard's launch of Diablo 3 last year, which moved 3.5 million copies in its first 24 hours and helped Activision Blizzard enjoy historical profits in 2012.
