Blizzard's latest game, StarCraft II, is being delivered in episodic formats. Sure, the multiplayer portion includes all three races but the single player, Wings of Liberty, includes just the Terran story. The next installment, Heart of the Swarm, will be launching at a later date but not much has been shown of it. Until now, that is, as a teaser trailer has appeared for the second part of the StarCraft II story. It isn't a very long trailer, being a teaser and all, but it should get you eagerly awaiting the game's release.
