Heart of the Swarm Opening
As seen from the last episode, the ultralisk pushes thor and the orbital command, causing three marines including Sgt. Patches off the cliff, following the building. At the bottommost part of the land, three marines landed on the darker, dry area unharmed, and the command center crash-lands on two marines except Patches. As the camera zooms out, the area is revealed to be lava zone.
An orbital command's satellite dish floats on the lava, and Bob the Ragelot lands on it safely. A zergling follows, landing on his head, and leaps toward the ground where the new zerg base is under construction. It sits on the mutating hatchery, coughs out Sgt. Patches' torn piece of clothing, and sleeps like a dog. Bob stares around doubtfully.
- This episode is proven that not only marines but also every other character do not die from the impact when falling.
- When the orbital command's satellite dish is removed, it becomes command center. The prelude episode reveals that the dish is still floating on lava.
- Patchling makes his return from "Zerg BM."
- Three races from "Three For All" and before may have transferred from grassland area above. The reason is unknown.
- The season 2 will use Heart of the Swarm expansion for new units.
- The announcement declares that the season 2 will be commenced on April 27, 2013.
- After the day when the prelude is released, the first episode starts with "GL HF".
