Milestone makers of… um… Twinkle Queen are making Nintendo 3DS games too. One of their early titles is actually a port. Karous 3DS is in development for Nintendo’s next handheld.
You may have seen Karous before as a Dreamcast game and later one of the titles in Ultimate Shooting Collection. Karous 3DS is slated for a summer release in Japan.
Their first title is set for spring and its Tank Beat sequel. Tank Beat 3 is in the pipeline, but no details about the game have been announced other than its genre, "tank battle action."
