A free update for Plants vs Zombies has appeared on the App Store, allowing iPhone owners to experience the eternal struggle of daisy against deadite from an undead perspective.

Version 1.9 introduces two new modes - I, Zombie and I, Zombie Endless - which let you switch sides and take control of the invading zombies. Those tulips won't know what hit them.

PopCap has also added leaderboard support via Game Centre, so that you can compare your zombie-slaying skills with the rest of the world.

And those of you obsessed with accolades will find four new achievements to satisfy your lust for virtual validation.
