EA-owned PopCap implemented a free-to-play model in Plants vs. Zombies 2: It's About Time, and within weeks the game was approaching 25 million downloads on the App Store. The developer's keeping quiet about any remaining ports; it's worth remembering the original Plants. vs. Zombies was gobbled up by practically every platform, including Xbox Live Arcade, PlayStation Network, and Nintendo DS.
