Akai Katana ("Red Katana," or, we suppose, "Red Sword," depending on how much translation you need) is a horizontal scrolling shooter released in arcades last year by shmup master Cave. During an event last week, the developer announced that the game is coming to the Xbox 360 in an upgraded version called Akai Katana Shin.

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."
