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 The three races have been replaced by three hybrid races.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.
This shows the AI using its superweapon (which is for the Bionics a lightning storm). Even more so, this was one of the dumber usages of the AI with its superweapon. Most of the times they choose a better target like your workers and hq.
