This is a new take on the traditional Starcraft races. The three races have been replaced by three hybrid races. The Bionics, the Infested and the Void Predators.
In this map you need to defend a xel'naga temple against waves of enemies. You pick your Starcraft Hybrid race and also select an elite starting force with up to 4 players (human or AI). Already downloadable at hiveworkshop, will upload it soon on moddb too after an update or 2.
