How do you take part in zombie mayhem?

I've only just realised if you play you get one of those retro mercenaries characters, do I just play a chapter with zombies in?

Make a account, link your account to your Playstation Network account. Once you've done that, kill a zombie, auto data upload it (Option menu) from the game. Log in to, synchronize it (Overview menu), and then wait.
