It was originally released on NEC PC-98 in 1994 but later received a port to 3DO in 1995 and releases for PS1 and Saturn in the following year. The Saturn version is superior to PS1 version because it is less censored, features original framerate videos (PS1 version dropped it 15 FPS) and contains the handy glossary. It also supports a light gun and a mouse.

Sadly, as can be seen in the shooting sections, cursor precision with the gamepad is either too low or the cursor is too slow for normal gameplay.
