Awesome awesome game. Production values of even the big console MGS installments. Looks, feels and plays like them too even despite the PSP's limitations. Bravo to the team for pulling this off on the hardware. Shame it didn't sell very well... Co-op is also extremely well implemented. Nothing too complicated or forced gimmick moves, just 1 more person there to back you up. Only complaint (as usual with MGS games) is the weirdness of the story, particularly in the final hour and how some things (some quite major plot points) just happen without explanation, rhyme or reason. One of the best parts is undoubtedly sky-hooking enemy soldiers out of the field and back to your base. Usually full of bullet holes. Bravo Kojima. Bravo. Hope there will be more like this even though it seems unlikely. Co-op works excellent in tactical espionage action.
