Koei's Samurai Warriors series is coming to PSP this spring in the form of Samurai Warriors: State of War.
This action/strategy game allows gamers to re-enact battles from Japan's feudal past when warlords such as Nobunaga Oda, Shingen Takeda, and Kenshin Uesugi struggled for control of the country.
The action is similar to Koei's other hack 'n slasher, Dynasty Warriors, with your character slicing through clusters of enemy soldiers in open battlefields or booby-trapped citadels.
State of War has a new story mode which allows you to align your characters with one army corp or the other and experience the conflict from their perspective. Once that has been concluded you can choose another group to align with and chop your way down another story path.
There's also a competitive multiplayer option that allows up to four players to test their tactical prowess and button mashing abilities against one another using PSP's wi-fi capabilities.
