I preordered it two months in advance. Like Wings of Liberty it pulls you in the moment you see the Openinng Cinematic.
Speaking of which:
In Wings of Liberty you played as James Raynor, who fought the Zerg, the Protoss and The Domion–someitmes at the same time–to get back the woman he onced loved: Sarah Kerrigan, who became the Queen of Blades and leader of the Zerg when Emepror Mengsk left her to die at the hands of the Zerg. An ancient relic purifies Kerrigan of the Zerg infestation and James whisks her away. Heart of the Swarm (Henceforth HotS) picks up three weeks after the events of Wings of Liberty (henceforth WoL). Prince Valerian helped Raynor crush the Zerg on their homeworld and bring Kerrigan back alive. Responsible for the deaths of 8 Billion people across countless worlds, Mengsk decides to finish Kerrigan off.
She is no longer the Queen of Blades but she is not quite her old self: Kerrigan can still command Zerg with her powers and it is for this reason Mengsk wants her dead. During her escape from the Dominion Kerrigan and Raynor are separated. Devastating news sets her on a path of vengeance and with the Zerg as the means. As the saying goes, hell hath no fury like woman scorned.
I haven’t cleared campaign yet but I am enjoying the game immensely. Until HotS I never used the Zerg. I only play Terran online so I’m learning the basics of playing Zerg in HotS’s campaign. In case you’re wondering no I haven’t played Protoss yet either and won’t until their expansion is (eventually) released. Once I have finished Campaign and have spent a sufficient amount of time playing online as Zerg I will write a proper review.
Kudos to Blizzard, it should be said. They’ve done an amazing job.
