We saw one Cave Story 3D
release date before, on Nintendo's quarterly release schedule
, but that turns out to have been inaccurate -- or the game has been delayed since then. In any case, scratch out the "Cave Story day!!!" note you put on your calendar's June 19 box and rewrite it under August 9. NIS will release the game in Europe sometime in September.
Along with announcing the date, NIS America released the box art image above, featuring protagonists Quote and Curly Brace checking out the 3DS logo on the side. The publisher also released a set of screenshots, each with a note that the game is "under development."
