We've already seen a major leak happen over the weekend, with the first teaser trailer for Heart of the Swam detailing a confrontation between Terran leader Jim Raynor and Zerg Queen of Blades Sarah Kerrigan, two former lovers who fought to keep humanity safe from the reapers, but saw Kerrigan sacrifice herself.
Now, after the release of the first installment, Wings of Liberty, which focused on the Terran faction, the next chapter will be called Heart of the Swarm and will concentrate on the Zerg race. StarCraft 2 is by far the most popular real-time strategy franchise in the world, and the decision of its developer, Blizzard, to split it up into three chapters, each focusing on a single race, was definitely interesting. After the leaked teaser at the beginning of the week, StarCraft 2: Heart of the Swarm has now received its official debut trailer, complete with gameplay footage from the upcoming strategy game as well as a few cinematic sequences.
