After many years of redefining stealth action on the PlayStation and PlayStation 2, Solid Snake is ready to make his debut on the Sony PSP with an all new kind of game, Metal Gear Acid. This game revolves more around a RTS-style gameplay system, where you're limited to a particular number of actions with each turn while avoiding or dispatching of enemies. Cards come into play throughout, and add a whole new deal of strategy that make the gameplay even that much more addictive. Metal Gear Acid looks to revamp the series in the most genuine of ways.
