Shin adds redone graphics, an unspecified new gameplay system, a new stage, and a 16x9 mode that redesigns enemy and bullet patterns to fit better on a widescreen display. The original version will also be available on the disc, which is due in Japan on May 26 in both standard and limited editions.
Unlike some other Cave Xbox games, the company announced that Akai Katana Shin will be region-locked when it arrives in Japan. "Hopefully one of our publisher friends will be interested as it looks grand." Aksys Games published Cave's Deathsmiles last year, so Cave does have at least one "publisher friend."
