Starcraft 2: Heart of the Swarm Vengeance trailer

Blizzard recently released a new trailer for the upcoming Starcraft 2 expansion 'Heart of the Swarm'. Focusing on the Zerg race this expansion is essentially a new game, with the 3rd installment focusing on the Protoss ('Legacy of the Void') which will probably be released in 2015 or so. The new trailer includes some content from other trailers but it's certainly pretty to watch and whether you're a SC2 fan or not I'm sure it's enough to interest you.

Blizzard always know how to impress with their CGI trailers.
