#9 Mass Effect 3’s Indoctrination Theory
As far as theories go, the Indoctrination Theory isn’t too much of a stretch, but it gives the writers of the game far more credit than they deserve for coming up with their especially poorly written ending for Mass Effect 3.
According to the theory, the game’s protagonist Commander Shepard has been ‘indoctrinated’ by the Reapers causing him or her to hallucinate various events in the game, as well as the entirety of the ending, which “takes place in his or her mind”. The existence of the theory serves to nullify the poorly written ending—which, if the theory is correct (it isn’t) isn’t as poor as you think. Phil Hornshaw wrote a great deal about the theory, and there’s an hour-long video (seen above) that attempts to explain what the theory is.
An end came to the Indoctrination Theory when BioWare rewrote a part of the game’s ending with the release of an update that extended the game’s ending in an attempt to properly explain what happened.
