Long ago, a tower defense game called Plants vs. Zombies took the world by storm. It was super good, we miss it, and shame on Popcap and EA for not making more mainline PvZ games. Luckily, Prikol Team and ESDigital Games are ready to fill that need with their new Steam release of Cats on Duty. This game has a serious PvZ vibe plus plenty of fresh ideas of its own. It's out now on Steam, and console versions are coming later this year.
