PopCap obviously are stocked up on Christmas cheer this holiday as it announces a free update for its iOS version of Plants Vs Zombies which includes new game mode, seasonal trimmings and Leaderboard support.
I, Zombie mode - already available on other versions of the title - let's you change sides and play through one free level as the shambling horde, with eight more levels and a Endless Mode available for in-app purchase at Crazy Dave's shop.
The developer has also introduced leader boards with the update with connectivity to GameCenter, and four new achievements - Better Off Dead, I,Win, Where the Sun don't Shine, and Undead Space - and new Bronze, Silver and Gold Mystery Sprouts.
A screen blow out for the new mode can be seen below.
