The PSP port of Shin Sangoku Musou 6 ( Dynasty Warriors 7 ) will feature the same Chronicle mode found in the PS3 version of the game with 2 player support via Wi-Fi . The PSP version will also have connectivity with the PS3.  As many as 4 players can battle it out in a new versus mode, not included in the console version of the game.

Tecmo Koei has no plans to release Shin Sangoku Musou 6 Special outside of Japan.
