ReZerged
Half the internet is rather excited about finally getting to see Starcraft 2's Zerg in action. So, here they are, doing what Zerg do best: Zerging.
Seems the game's being pretty playful about their infamous swarming nature, which should make for good times, and plenty of nightmares soundtracked by the phlegmy sound of chitin being rendered asunder. If that video's anything to go by, there's also actually a pretty decent sense of scale to Starcraft 2, which I wasn't entirely expecting. I do like to zoom my RTS cameras way out.
You can also see the intro cinematic here, but we're all far too grown-up to care about cutscenes these days, right?
