Love is in the air. But this is not your typical romance novel.
At the end of the first StarCraft II game, Wings Of Liberty, human Terran hero James Raynor transforms the evil Queen of Blades back into her human form, his girlfriend Sarah Kerrigan.
Kerrigan reclaims her memories. She is human, save for the snake-like steel tendrils which still adorn her head instead of her once fiery red hair.
Heart Of The Swarm is the second part of this trilogy and continues the epic sci-fi saga as it tells of her return to power.
Can Raynor and Kerrigan finally find happiness and comfort in each other's arms? Can the human race forgive Kerrigan for annihilating millions when she was the leader of the alien Zerg swarm?
Playing the 20-odd missions in the single-player campaign reveals the story. Without giving away any spoilers, it is fair to say that Kerrigan will find herself once again as leader of the Zergs and she fights on purely because of love and vengeance.
In this expansion, she is the protagonist. Blizzard has added role-playing elements as she gains additional powers as she levels up after each successful mission.
Some powers are active skills to damage enemies and heal allies, while others are passive and can help improve resource acquisition and management - one of the two key skills needed to win in this game.
The campaign takes about 15 hours to complete, but this game can be replayed endlessly because of its multiplayer features.
