One of the more bizarre games to launch with the PSP, Metal Gear Acid pits Solid Snake against a base full of soldiers with only one weapon: a...deck of cards? That\\\'s right; in this card-game, turn-based strategy game, you\\\'ll need to construct a deck drawn from over 200 cards based on events and characters in previous Metal Gear games, and use it to defeat numerous soldiers, robots, security cameras, and a few bosses. GameSpot\\\'s Game Guide to Acid gives you a full walkthrough and plenty of deck construction tips to help you out!
