To the untrained eye, it might look like a campaign video, albeit one that's a bit over the top. Donald Trump tweeted out a video Monday that appears to have originated from this vidme upload. The video warns that "humanity is under attack" and that "one very specific man might be all that stands between humanity and the greatest threat of our brief existence." Martin Sheen's authoritative voiceover has been co-opted from a speech in which Sheen's character in the "Mass Effect" series, the Illusive Man, is discussing the threat of a deadly super species that wants to wipe out the human race, setting in motion the events of "Mass Effect 2." In fact, the Trump video mirrors the trailer for "Mass Effect 2" quite well, including ratings and scenes featuring allies and critics alike.
