The cell shaded Ac!d
You have a choice of story mode and area mode. The story mode obviously takes you to the main game and the arena mode is where you can battle bosses from the previous Metal Gear Solid games. There are two bosses per battle and there are two bosses from each MGS game. Ocelot and Liquid Snake from MGS1, Fortune and Vamp from MGS2 and The End and The Boss from MGS3. There is also Teliko from Metal Gear Ac!d 1 and an alternate form of Venus. You also gain some new cards from beating these bosses in arena mode. There are 500 cards to collect. The Solid Eye comes with the Metal Gear Ac!d 2 package but it's overrated. Sure you slip it onto the PSP and you can see everything in 3D, but it can only be used for a short time. You eyes will start to feel weird and start to hurt after 5 minutes. Overall this game is a neat little package with all of your MGS goodies inside. It's definitely worth the buy!
