PopCap have updated their 5-star strategy game Plants vs Zombies with a whole host of new features that will quite literally have you soiling your plants.

For starters, a new Zen Garden has you collecting, watering, and fertilising the fruits of your labour, with coinage rewarded should you prink and preen to a satisfactory level.

You can then spend that money on some lovely plants and traps, or even new mini-games such as the considerately named Zombiquarium and Zombotany.

Beyond this update, Game Center integration is soon to be upgraded and will throw in with some extra unlockable achievements.

More news on those refreshes when we get it - until then, you can pick up Plants vs Zombies from the App Store for $2.99.
