Cave is famous for its bullet hell shooters. Not every game Cave makes is a shmup, but those games are what made Cave, well, Cave. And the Tokyo-based game maker's latest title certainly isn't a shooter.
Dubbed Instant Brain, it's an adventure game for the Xbox 360 - Cave's first.
As the Japanese internet is quick to point out, the game features character design from erotic illustrator Kamiri Iruma and music from erotic game music composer Ryu Umemoto. To be fair, Umemoto composed the soundtrack to Cave's last big arcade shooter Akai Katana.
Check out Instant Brain's opening movie below. Good to see Cave branching out.
