Will Sarah Kerrigan's path of destruction lead her down a further pit of evil, or is there a sliver of redemption still left in her conflicted soul? Starcraft 2: Heart of the Swarm takes us deeper into Kerrigan's heart of darkness, and the new Vengeance trailer displays an antihero who may not be worth saving, unless it's Jim Raynor you're talking to.

"I moved heaven and earth to bring you back Sarah," exclaims Raynor at the beginning of the trailer, and it's his plea which may go unanswered, especially when Kerrigan promises that "worlds will burn." Along with the obviously stunning visuals in Vengeance, it's also great to hear Tricia Helfer once again voice Kerrigan, as the Battlestar Galactica actress hits the right vengeful notes in playing the Queen of Blades.

Starcraft 2: Heart of Swarm comes out March 12th for PC and Mac. Check out the Vengeance trailer below and tell us if Kerrigan needs to dial it down just a bit.
