There is restriction in terms of the distance between players in co-op play—players will be able to act individually and go where they please. You can play with both friends and non-friends. Cross-play between platforms is not supported.
A “Free Co-Op & Demo Version” of Dynasty Warriors 9 will also be released on November 1, which allows users to participate in online co-op with friends, as well choose and play the openings of three officers from the game’s roster of 90 (for about one to four hours of play time). For users who only care about certain officers, individual character will also be sold for 200 to 400 yen, depending on their scenario’s length. Trophies / achievements cannot be earned by playing this version of the game.
