Have the PlayStation 3 version of Samurai Warriors 3 Z or this year’s Samurai Warriors 3 Empires? Keep your save data because you can use it to unlock all of the characters for Samurai Warriors 3 Z Special.
Samurai Warriors 3 Z Special is a portable version of the PS3 game (which is actually an upgraded Wii port!). The PSP release supports two player co-op and a four player versus mode through an ad-hoc connection.
After Samurai Warriors 3 Z Special comes out on February 16, Tecmo Koei plan to support it further with downloadable content.
