Mind Control Is a Purchasable Commodity
The first of the theories we’ll talk about deals directly with mind control, and hypothesizes that it has now become a marketable commodity. There are multiple scenes in the game where we see what appears to be sentient masked human-like characters, watching and observing the zombie-like humans. When you make your way into the final laboratory area of the game, we also see humans studying strange creatures in captivity, including the blob that you control at the end. There’s also a section where the boy is forced to blend in with the zombies and display basic motor skills like walking and jumping.
Taking this theory further, it states that the boy himself is the next step in mind control testing. Everything, including the security measures of facilities, were designed as a test for the boy. It could also explain why many of the scientists and humans are trying to help the blob escape at the end of the game. What reason could there be to put such intricate puzzles and security in these random places in the game, if not to test the boy and ultimately have him control the blob? Of course it’s just one of many theories, and things get even a bit crazier.
