One of PopCap Games' most popular titles is now free for the time being: Plants vs. Zombies. Released back in 2009, I used to get on the train going to work each day with my netbook playing Plants vs. Zombies. I absolutely loved it and so did our reviewers for the PC and Xbox 360 versions.
The SD and HD versions usually run for $3 or $7 for each version but right now, you'll be able to get them for free on your iOS device. Looking through PopCap's social media, they didn't make an announcement so this could be a system glitch so get it while you can.
Back in August, we reported on the potential of a Plants vs. Zombies 2 that could come in late spring. As it's been four years now since the original came out with the game spreading to other platforms over the last three, I'll be anxiously waiting to throw down some cash for the next one.
