As promised, the first Mass Effect 3 details have arrived in US retailer mag Game Informer. According to the mag, BioWare's third and final sci-fi instalment kicks off with Shepard on Earth, facing trial for the events that occurred during the recently released Arrival DLC for Mass Effect 2.
In the middle of the trial, the Reapers invade, and it all kicks off. Mass Effect 3's prologue involves Shepard's escape to the Normandy, and subsequent mission to yet again gather allies to battle the Reaper troops.
