Plants vs. Zombies for iPhone [$.99] got some new and exciting stuff this morning in a fresh and free update. At the top, the game finally now supports Game Center leaderboards. It can also now boast some parity with the series’ PC, Macintosh, XBLA, and DS adaptations — I, Zombie mode is now supported and can be purchased via IAP in Crazy Dave’s shop.

I, Zombie, if you’re not familiar, is a table-turning twist that lets you play as the undead horde . You’ll get one free level in this update, and eight more, as well as an Endless take on it, if you do decide to pony up the dough. Holiday hats have also been introduced via this update because, hats.
