User Rating: 9.6 | Infected PSP
Single Player:

Fun, but shallow. Too short, which is what caused the game from being perfect. Graphics were pretty good on the psp and the gameplay was excellent. Not to mention, the framerate was the best i have seen on the psp. Tons of blood and gore flying everywhere. amny guns you can choose from, and detailed, gross looking zombies waiting for be torn apart. but, any of you psp fans will blow through the campaign in less than 8 hours. You will actually probably beat it in one sitting, which was the one thing that dissapointed me. Other than that, sound and voice acting was great. This game is definitley worth your time of you love blowing up zombies.

Multiplayer:

Strong multiplayer mode online. (Yes, it has infrastructure) Very fun, doesn't lag, and you get ALL the gory action from the single player mode, including ALL the weapons as well. The MP is extremely enjoyable for any gamers on the go.

conclusion:

Wow. I believe this game is the best game that has hit the psp so far. Anyone with this marvelous handheld system should go pick this game up right away. I did, and I'm extremely satisfied.
