This is seriously twisted.
I don't know if this is fake or not but it is truly fucked up. Mentalist Derren Brown wants to instill real fear into people, not the type of fright you get from watching horror movies. So he designs this "arcade" zombie shooter that can put people into a catatonic trance by flashing lights. Once the person is zoned out, he moves them to a building that is mocked up just like the game.
Watch and see what happens to the unwitting victim of this experiment.
Note: Not Safe For Work language as the victim drops audible F-bombs in his shooting frenzy.
