Dragon Ball Z: Extreme Butōden hit the Nintendo 3DS in Japan last week, and those of us who can’t wait for a potential localization have been sinking some time into the import version. In addition to a moderate roster of playable characters, the game sports an impressive amount of “Z-Assist” characters. While a few of these extra characters have been relegated to paid bonus items, a few have been made unlockable via button-input codes. Check the list below to expand your roster! Have we missed any? Let us know!

Button press codes should be made on the game’s main title screen.

Dragon Ball Z: Extreme Butōden launched in Japan 11 June 2015. First-press copies of the game come packed with bonus content, including a downloadable version of the Super Famicom game Dragon Ball Z: Super Butōden 2 (previously included as a part of the J-Legend Retsuden compilation game; albeit now with replacement music). Arc System Works developed the game for Bandai Namco. The developer previously worked on the Bukū… / Supersonic Warriors games on the Nintendo GameBoy Advance and DS.

Dragon Ball Z: Extreme Butōden is currently available for order from CDJapan. The Nintendo 3DS / New Nintendo 3DS are region-locked; a Japanese system is required for the game to play.
