Plants vs. Zombies 2 utilizes the same lane defense gameplay that made the original game a hit, but it also offers up some new plants, new gameplay mechanics, and time travel to settings like ancient Egypt. With 16 million downloads, it represents EA's most successful mobile game launch to date.
During EA's Gamescom press conference this morning (via Joystiq), franchise director Tony Leamer also announced an upcoming content pack for the game, called "Far Future." There are no further details about the content pack at this time, so it is unclear when it might be released.
Though Plants vs. Zombies 2 is a freemium game, much of the content is available without paying. Our sister site TouchArcade has released a guide on how to spend as little money as possible (which actually shows that gamers can play through the entire game without spending any money) and has also published a detailed review of the game that calls it an "incredible sequel."
Plants vs. Zombies 2 is a universal app that can be downloaded from the App Store for free. [Direct Link]
