They did one of the Bestbuys in my area, and we are having a zombie walk here. Not sure if its the same thing or not.

The Best Buy thing was a midnight release of the game. They closed down half the store, and set it up to be like a treatment center and you had to walk through it to get the game. Then later in the day the army showed up and zombies broke lose, they started shooting blanks and what not it was sick.
