The omegalisk is a zerg heavy assault strain in the same vein as the ultralisk but substantially larger. It was the ultralisk concept for StarCraft II but ended up as a special campaign unit.


An omegalisk was used to defend the tunnels beneath Char which housed Sarah Kerrigan's nydus network.[1]

Dark Prelate Zeratul observed omegalisks in an apocalyptic vision of the future. The creatures were part of Amon-controlled Swarm that annihilated the protoss during their last stand.[2]

Game Unit[]

In the StarCraft II: Wings of Liberty mission, "In Utter Darkness", an omegalisk is located in each of the three zerg bases. No research points are awarded for killing them, but they are counted towards the kill score.[2]

One appears in "Belly of the Beast", attacking destructible rocks which General Horace Warfield's marines hide behind.[1]

It uses the ultralisk portrait and model, albeit a larger one. If Zeratul casts Void Prison on one, the sphere will be abnormally large.

The omegalisk

The omegalisk was a concept for the ultralisk in StarCraft II. It had spiked tentacles in addition to kaiser blades. The tentacles could attack multiple opponents.[3]

The ultralisk tentacles were reverted because the skewering was too "random".[4]

Additional abilities in the map editor indicate that the omegalisk was intended to function as a cross between the torrasque and noxious ultralisk strains in the Heart of the Swarm campaign. The unit has a chrysalis ability similar to the torrasque along with the damaging cloud of the noxius, though both are represented by buttons or are incomplete.

  4. This is the original concept piece for the 'new' Ultralisk in StarCraft II. The tentacles were fun to watch while skewing marines, but in multiplayer, the 'random' factor of that skewing did not fit into the competitive gameplay nature of StarCraft as well.
