One thing that StarCraft II: Heart of the Swarm does extremely well is present the monstrous Zerg as an undulating blanket of slimy, unspeakable nightmares. During the course of a few of the large scale battles when there were literally a hundred Zerg units crashing into enemy defenses, my skin actually crawled and I felt a flash of fight or flight. Something about the way the units are animated… it’s creepy. And when they’re all lumped together it’s close to terrifying.
