Dynasty Warriors lets you return to the battlefields of ancient China to fight an army of ruthless soldiers. As one of 42 playable characters, you'll have access to powerful weapons and lethal fighting skills. Unique to the PSP version are a battlefield area system, which creates new strategic gameplay and shorter periods of play, and an officer system that gives you control of your bodyguards. With hundreds of bodyguards to discover, you can collect and select which officers to take in to battle and also trade them with your friends using the Memory Stick Duo.
