Scott Pilgrim vs. The World (and, perhaps more appropriately, Shaun of the Dead) director Edgar Wright, the upcoming film's video game adaptation will feature some sort of zombie survival mode accessible through the main menu.
Of course, you'll need a bit of know-how in order access the mode. On the game's title screen, simply input down, up, right, down, up, right, down, up, right, right, right -- that's "DUR DUR DURRR," the universal mating call of all undeadkind -- and then prepare to press whatever the "Punch" button might be on the console upon which you're playing the game. Prepare to press it a lot.
