Dragon Quest IX: Sentinels of the Starry Skies for the Nintendo DS will be launching in the US on July 11. The game will contains special modes that let players share their adventure with others, allowing up to four players to team up via a local wireless connection and experience the fun of tackling challenging monsters and dungeons cooperatively with their own characters. Players can even leave the game active in their backpacks, pockets or purses and still interact with other players via an interactive “Tag Mode.” Information about players’ characters can be wirelessly transmitted to others, and treasure maps and customized greetings can be exchanged automatically by players who come within range of one another when their games are set to Tag Mode.
