Today, Blizzard detailed the many new units that will show up in Starcraft II: Heart of the Swarm. Rather than just describing a bunch of abilities and units, they decided to also show them in action in this Protoss vs. Zerg match.

Over the course of the 24-minute match, you can see many (maybe all?) of the new Protoss and Zerg units in action, and Rob Simpson and Day[9]’s shoutcasting helps keep track of what you’re seeing.
Man, just when I was starting to get tired of Diablo III, Blizzard reminds me how much I like StarCraft II. Well played.
