The anniversary edition is nearly identical to the 10-year-old original game, which is widely considered to be one of the most influential games of all time. The gameplay is optimized for touch-screen devices, with resizable custom controls.
There are two major improvements from the original, too: mission retry and autosave mode, which should greatly lessen the chances of players smashing their mobile devices in frustration.
As far as compatibility goes, the game works on the iPhone 4 and 4S, 4th generation iPod touch as well as iPad 1 and 2.
The list of supported Android devices includes HTC Rezound, LG Optimus 2x, Motorola Atrix 4G, Motorola Droid X2, Motorola Photon 4G, Samsung Galaxy R, T-Mobile G2x.
On the Android tablet front, Acer Iconia, Asus Eee Pad Transformer, Dell Streak 7, LG Optimus Pad, Motorola Xoom, Samsung Galaxy Tab 8.9 and 10.1, Sony Tablet S and Toshiba Thrive are supported.
The game is available for $4.99 in the iTunes App Store and Android Market.
