The original Plants vs. Zombies introduced us to warfare between spitting plants and shambling zombies. If you’ve never played PopCap's twist on tower defense (or simply have yet to get it on PC), you’re in luck.

EA has rotated Plants vs. Zombies into the “On the House” program, making it the second such title. That means, if you weren’t quick enough to pick up the inaugural offering, Dead Space, you’re out of luck. 

Don’t let that happen again. Head over to Origin now to get your free copy of Plants vs. Zombies.
