This is a summary of the following:
The speaker is MatPat, the host of Game Theory, a YouTube show that analyzes video games. He is talking about Mass Effect, a sci-fi game series where the player controls Commander Shepard, who fights against an invasion of galaxy-destroying machines called Reapers. He focuses on the controversial ending of Mass Effect 3, where Shepard has to choose between three options to stop the Reapers, each with a different colored beam of light. He argues that the ending is a lie, and that Shepard is actually being brainwashed by the Reapers through a process called indoctrination. He presents evidence from the game and the science of sound to support his claim. He also mentions a mysterious child that appears in the game and haunts Shepard's dreams, and suggests that he is a Reaper construct. He ends by promoting Dollar Shave Club, a sponsor of his show, and announcing his next episode on Splatoon, another video game. He asks his viewers to subscribe and wait for part 2 of his Mass Effect theory.
A possible concise summary is:
MatPat explains why Mass Effect 3's ending is a brainwashing trick by the Reapers using sound and a fake child. He advertises Dollar Shave Club and Splatoon before teasing part 2.
