Mass Effect 3 "Earth" DLC trailer is a call to arms

"The Earth is ours. And if they want it...they'll have to go through us," growls Alliance Officer David Anderson (aka the incomparable Keith David) in this spectacular trailer for the free DLC pack for Mass Effect 3, "Earth." This is some downright spectacular marketing.

If there's one thing Bioware knows how to do better than just about anybody else in the industry it's how to give space nerds like us goosebumps in trailer after trailer. It's pretty hard to imagine Mass Effect 3 multiplayer fans watching a trailer like this and not being at least tempted to start playing again.
