Teaser site time! Any guesses on this new Cave teaser site? The URL is 6meikan.jp, and we have a mysterious date of 11.11.11, or November 11. This is probably something new, as the page states that this stands for "A new proposal from Cave."
Like I said, I've got nothing. I have this feeling that it's not a shoot-em-up, though.
Check back in a few days.
