Not that bothered about the game itself (a multiplayer-only FPS based on a particularly silly roleplaying game where someone thought 'You know what the gritty near-future cyberpunk genre need? Elves and Trolls!'), but the music's great. It's called "Baiana", by the Brazilian group "Barbatuques". Me likey.

ALSO: some updates and concept art on the upcoming LEGO MMO.
