Yesterday we got the biggest and brightest announcements from the VGAs posted. Today we’re bringing you even more coverage, like this announcement trailer for Mass Effect 3. In the trailer we see Earth under attack from an unknown race of mechanic terror, which we assume to be reapers. Once again Commander Shepard has the fate of humanity within his hands, and it is up to him to once again save his race from imminent doom. Check out the trailer below.
