Since the latest update of the game was released in February 2011 Plants vs Zombies HD has already become an instant classic. Available on many platforms such as iDevices, Xbox 360 and PS3, Plants vs Zombies is an advanced tower defence game in which the player must use different species of plants to defend his house from zombies. The HD version of the game offers many improved features on the iPod/iPhone, such as massively improved graphics, improved game modes, new achievements and more. The game retails at $6.99/£3.99, some may say it's a little overpriced but I think that's a little harsh, the game offers a lot more than the iPod/iPhone version and it will surely keep you playing for hours.
