A very good card-battler for the PSP.
The second game fixes all the bugs that were in the first game, or most of the annoyances in the old game. The old game featured a more classic Metal Gear Solid look and appeal to it. Metal Gear Acid 2 features more of a comic book style of graphics makes the game look more vivid. The movement system has been improved to where instead of having to plan out all the things you are going to do ahead of when you are going to move you can now do it along the way. Examples are: you can stand an crawl at will during movement , you can punch during movement and you can flatten against the wall at will during movement.
The new cards added are good and there are a lot of new ones. As for the extras, the Solid eye is a nice bonus to have with the game and by unlocking cards you can get movies in the Solid Eye theater which are nice to have. The solid eye is nice to have but can give you headaches if used too long and falls apart easily. For any Metal Gear fan who has a PSP this is a must have. For all those who don't know if they want this game consider this, if you own a PSP, like both card-battlers and third person shooters, and want a tactics game for the PSP this is a good one to pick up
