The perfect PSP game!
The difficulty on Medium is tuned to keep you on your toes. The story is fairly good, but it is the quality of the graphcs and gameplay that really set this title apart. I really can't find any flaws with the game. The entire time I played not one thing stood out as something I would have done differently. Seriously, this game is a dream for folks that play hand help titles.
I have to say again how exceptional the graphics are, crisp, great textures, everything is top notch. The controls are also perfect. Very easy to pick up, hard to fully master. The weapons all have their own particular benefit and picking what weapon to use is critical. I also liked how you could control your teammate. Using them effectively will make the game much easier (and enjoyable).
I can't believe this game was not up for GoTY awards...it is easily the best PSP game ever. Now, where is the sequel?
