Mass Effect 3 trailers depict the fall of Earth

EA has released a pair of shiny Mass Effect 3 trailers.
The first, entitled Invasion, is a live-action trailer showing the first moments of the Reaper invasion of Earth.
The second, entitled Fall of Earth, contains nothing but beautiful gameplay footage that shows off some of the new locations Shepard will be visiting and the new powers he’ll be employing as he fights to reclaim the Earth. (Well, I say “he”. Everyone know that FemShep is the sensible choice.)
Mass Effect 3 is due out on PC, PlayStation 3, and Xbox 360 on 9 March 2012.
