User blog comment:GeorgePowell/How do you think Mass Effect 3 will end?/@comment-3315329-20110713022752

Given that Bioware said the game will take branching paths, I assume there will be at least two endings. This is pure speculation, but here it goes. The protheans had a colony on Mars 50,000 years ago, when humans were starting civilization. We that the protheans were aware of humanity before or during the Reaper invansion due to the beacon on Eletania. So it may be possible the the protheans gave humanity a trump card of some sort hidden on earth. In a good ending, Humanity may use this or some other creative plot device to destroy the Reapers. In a bad ending, I would love to see all of the galaxy's civilizations to be consumed and either Shepard or another human group hide away and prepare for the next invansion much like the protheans before them. Though I doubt that will happen. A more likely bad ending is that Shepard dies stopping the Reapers.
