Metal Gear Ac!d has been massively enhanced in this follow-up to last year's strategy-oriented PSP side-story. The team has revamped the visuals to be brighter and more clearly defined on the impressive PSP screen, but coolest of all is that the game comes with a 'Solid Eye' 3D Viewer - a device that attaches to your PSP activating 3D special effects. This, friends, is the world of Metal Gear brought to life as never before! By using the Solid Eye viewer, bonus videos can be observed in 3D, plus images that have been imported from Metal Gear Solid 3: Subsistence via USB.

Although the gameplay remains based on the card system, there are new 'move' modes in MGA 2 that allow you to control Snake directly. Commands can also be issued real-time now, making for a faster turn of events requiring you to think on your feet against the pressure of the clock. Cards still govern the majority of Snake's movement and combat, however, and the range of possibilities has more than doubled from the last game from 200 to a colossal 500! New cards have been introduced, among them Linkage Cards that grant bonuses when combined, and Trap Cards that generate context-sensitive attacks. Your strategic options are further expanded due to each card being upgradeable to become more powerful.

When you've been playing MGA 2 for a while, you'll no doubt have created a huge stack of great cards in your own personalised deck. If you really want to put your deck to the test, you can link up with a friend via Wi-Fi and compete head-to-head.

If any or all of the above seems daunting, don't worry! Konami has incorporated a new Tutorial Mode that details the fascinating ins and outs of Metal Gear Ac!d gameplay. Konami wouldn't want anyone to miss out on this amazing new Metal Gear experience.
