Cave Co., Ltd. (Computer Art Visual Entertainment) is a Japanese video game company, known primarily for its manic shoot 'em ups. Cave remains one of the most active makers of arcade shoot-'em-ups in the Japanese market.
Cave's arcade titles have used various arcade boards over the years. Earlier titles used a Cave-designed board based on a Motorola 68000 CPU, whereas later releases moved over to the PGM (Poly Game Master) hardware, and then on to boards based on the Hitachi SH-3 CPU. Cave dabbled in PC-based hardware for DeathSmiles II, but with Akai Katana, they have gone back to the old SH-3 hardware.
