Legacy of the Void
4th race in StarCraft II will be a Hybrid genetic mutants thus creating the Protoss and Zerg DNA?
Have you noticed that the patch 1.5 edited selection races so that there remain open box for the next race?
And that's what was revealed in the files Beta HotS do not know yet if the fourth race Hybrids appear already in the second expansion or in the third Protoss. For nothing more than offer a few icons and images free beta. So far we do not know the unit, but small hack can unlock menu with a choice of four races!!
