Death from Above

Death from Above is the second-last mission of Heart of the Swarm.

The Terran Dominion activated a potent anti-zerg psionic weapon, the Psionic Destroyer, which took advantage of the zerg hivemind to destroy them. However, the primal zerg, which lacked this hivemind, were unaffected.

The Destroyer was powered by several power links. Destroying a link would temporarily depower the Destroyer, and destroying them all would shut it down.

Kerrigan dispatched Dehaka and his primal zerg pack to destroy the power links. Whenever a link was destroyed and the Destroyer depowered, Kerrigan's own zerg would do as much damage to the Dominion forces as possible.

Eventually, the Psionic Destroyer was destroyed.
