Shian

The Shian were one of the three races dropped from the final version of Unreal 2: The Awakening along with The_N and Striders.

Originally one of the missions had the player investigating an underwater colony,which is where they meet the Shian. Described as jellyfish-like monstrosities, they used their psychic abilities to summon all the sea creatures in the area to serve in the battle.

The pawns ShianWorker and ShianWarrior appear in the editor that shipped with Unreal 2, but no models or code are contained within.
