Just as promised, PopCap’s hit casual tower defense game, Plants vs. Zombies, has gone mobile for the iPhone and iPod touch.

Plants vs. Zombies for iPhone and iPod touch marks the first adaptation of our wildly popular ‘flower defense’ game to a new platform, and we’re excited at how well it has translated to the iPhone and iPod touch,” stated Andrew Stein, director of mobile platforms at PopCap Games.

Plants vs. Zombies is a unique tower defense game that oozes character as only PopCap games can.  In the game you will be defending your home from waves of zombies, each with their own special traits, by planting 49 different plants, some of which are offensive and some defensive.

The game features a total of 26 different types of zombies to defeat, 50 levels in Adventure mode with different surroundings, achievements, Quick Play mode, and amusing animations and music.

Although Plants vs. Zombies was originally developed for desktop computers, the game’s basic control and gameplay elements help ease the transition into mobile form.  Some elements are even easier to control on the iPhone as opposed to on a desktop computer, such as collecting the all-important sunshine falling from the sky which is required to obtain plants.  PopCap has done a fine job with the UI as well, placing necessary items in easy to reach areas and requiring the game to be played in landscape mode.

Plants vs. Zombies is available at the low price of $2.99.
