The first installment of StarCraft II focused on the Terran side of the three-way galactic battle in Wings of Liberty. At BlizzCon last weekend Blizzard released the preview trailer for the upcoming second installment.
Heart of the Swarm brings the Zerg Queen Kerrigan back into the forefront as she proceeds to royally destroy everything Terran. Other than seeing some FMVs of Kerrigan you’ll also see a few glimpses of the new units.
Some early information from Blizzard indicates that there will be 10 fewer missions in HotS than there were in WoL. Wings of Liberty had 30 missions total. Blizzard reps say that they received a lot of complaints from fans about the number of missions so they attempted to appease fans with fewer, more varied mission sets.
There is no official date set for the release of Heart of the Swarm but some reports have the game out in about a year to a year and a half.
