For those who watch lat night’s episode of The Walking Dead, you may have caught the full “take Back Earth” trailer while you were patiently waiting for those pesky commercials to end. Those who missed the episode or just don’t watch the show can check out the trailer below in all its glory. If you weren’t motivated to reclaim Earth before, you will be after this. There is also a disclaimer at the end of the trailer to catch the extended version tomorrow. Mass Effect 3 releases on March 6 for the Playstation 3, Xbox 360 and PC.
