Socom

I've found that good multiplayer psp games can be hard to find with the playstation portable console, but SOCOM hits the mark. Created by Zipper Interactive, it features sniper rifles, machine guns, ballistics, grenades, and all kinds of high tech weaponry. Its all mirrored after the US Navy Seals.

What makes it so good for multiplayer? You can have up to 16 players in combat at a time, many different modes, and real-time voice chat, which is a good bonus. Its kind of like a better version of the half life games, and If your ever looking for a realistic and well rendered landscape, the levels in this psp game provide that experience!
