Metal Gear Acid has the storyline of a Metal Gear Solid game, and the play of well, not a Metal Gear Solid game. You are forced to use cards(weapon,armor,health) to inflitrate enemy bases. Your cards are stored in a deck that you bring with you, and you choose which cards to use during your turn. You can buy cards, and switch out cards from your deck to the stock. Although the "card system" seems like a flaw in the game, it really isn't. By taking turns with your enemies, this game requires more strategy and thinking, rather than just button mashing in the direction of your enemies. The story is actually not that interesting, and the game has a nifty "movie skip" option. Overall, Metal Gear Acid is a great game for gamers who love RPG's and James Bond style of games.
