PopCap has released a free update for its dangerously addictive iOS game Plants Vs Zombies, version 1.9, which lets you take control of the zombies in a new gameplay mode.
The 'I, Zombie' and 'I, Zombie Endless' modes let you take control of the undead in nine completely new levels. Dammit, we're going to be hooked again.
The update also adds four new achievements to unlocks, and three new leaderboards which also link into Game Center.
Having already hit every current phone and gaming platform known to man, the zombies will be continuing their stampede to yet another new platform next year as a launch title when Vita releases in the West on February 22, 2012.
Check it out through iTunes.
