The Reckoning (Heart of the Swarm mission)

The Reckoning is the final mission of Heart of the Swarm.

The Mission
Augustgrad was defended by three strong-points preventing zerg forces from entering the city from the outside, although Sarah Kerrigan and her own zerg had already entered the city, along with the Hyperion and Raynor's Raiders.

Powerful Dominion defenses such as Pride of Augustgrad battlecruisers and the Odin, plus groups such as Alpha Squadron and even the reconstituted Sons of Korhal were present to defend Mengsk's Palace from the zerg.

Kerrigan's forces were able to destroy the three main Dominion entrenchments, which subsequently enabled Zagara, Dehaka, and Alexei Stukov to send their own troops into the city to reinforce Kerrigan.

The joint zerg-Raider forces were able to fight their way to Mengsk's Palace where they shattered the palace gates. Kerrigan entered it alone to deal with Mengsk.
