Mass Effect 3
's 'Earth' multiplayer DLC launches on Xbox 360 next Tuesday, July 17, at a cost of zero space bucks. The content is multiplayer-focused, and that's about all we know – we're taking a wild guess that the locales it'll offer are based on Terra Firma regions.
That said, if rumors from back in June
pan out, the DLC will head to Rio, Vancouver, and London, and several new human classes will be added. BioWare has yet to confirm any new details about the content, but we expect to hear more in the near future.
