Popular mobile game Plants vs. Zombies is free today in the Apple App Store.

The usual price tag has been dropped for iOS users, who can now play the garden slasher app for free. Both the iPhone (regularly $2.99) and HD iPad ($6.99) versions are available at no cost.

PopCap’s director of editorial and social media, Jeff Green, revealed the deal(Opens in a new window) via Twitter today, writing “I’ve heard this game is pretty good. Might as well give it a shot cuz #YOLO.”

Neither PopCap nor Apple provided an explanation for the freebie, or revealed how long the reduction will last. But anyone who hasn’t already dropped a few dollars on the game since its 2010 arrival should probably act fast.
