EA’s released a live-action trailer for Mass Effect 3. The trailer lets you witness how the invasion of Earth began, and shows thousands of Reaper ships landing on the planet, triggering a full-fledged war. This is pretty much the same video that kicked off EA’s press conference on Monday evening, but there’s some extra bits as well. Watch it after the break. The BioWare RPG launches worldwide on March 6, 2012.
