How easily can out minds be fooled?
Here's a video of a guy who gets tricked into thinking that he's in the middle of a real life zombie scenario.
He goes into a bar with his mates, and decides to play a zombie arcade game that's conveniently placed near the entrance. Little does he know that machine has been set up by an illusionist Darren Brown, who is doing a segment for his TV show.
I'm not totally sure if the whole thing, including the guy who's tricked, wasn't a set up for the show... and that it is in fact us the audience who is being duped. But have a look for ya self... it's still pretty cool and slightly scary towards the end when the guy starts freaking out.
At least the guy 'playing' got more action out of it than the guy who though he was playing Silent Hill.
