A must-get for the PSP, regardless of whether you like shooters or not.
The graphics in this game are amazing. The developers really paid attention to the small details and in doing so, made one of the most visually impressive games on the PSP. Shooting enemies produces bloodspots on their bodies and the character models look great and animate smoothly. And to compliment those chraracter models, the game has ragdoll physics. The cutscenes in this game are the best I have ever seen in any PSP game.
This game sounds great! The voice-overs are great and the live orchestra soundtrack fits the stealth and action sequences perfectly.
The single player in this game is great. There are enough missions in this game to keep you busy for a long time. You can finish the story mode on any of the three difficulties and then replay the missions to unlock new weapons or bonus levels. The online play is incredible. It is so good that it can be considered a game by itself. Gameplay consists of standard Deathmatch and Team Deathmatch and has two other modes, Objective and Rogue Agent, the latter which consists of one agent fighting against everyone else in order to get points. Objective is a mode in which the two teams have to complete different objectives such as disarming a bomb or stealing uranium.
If you have a PSP and are able to play online, you have to get this game. It's one of the best games on the PSP and the best shooter too. If you want this game only for the single player, it isn't as good but it'll keep you busy for a long time.
