Considering it's a Japanese release and probably not a very popular genre here on OCN, I didn't post this in the news section.
Cave announced earlier today that Akai Katana will be the latest of their shooters to receive the Xbox 360 treatment.
Set for release in Japan on May 26th, the game has been re-done in HD with 16:9 support along with new stages and gameplay modes.
If you have a Twitter account, be sure to pester Cave about it. We're shooting for at least a region free release.
