Crypt Killer (released as Henry Explorers in Japan) is a 1995 light gun shooter video game developed and published by Konami for arcades. Ports for the PlayStation and Sega Saturn were released in 1997, along with a CD-ROM conversion for Microsoft Windows released exclusively in Japan the same year. The Saturn version makes use of Sega's Virtua Gun (released as the Stunner in North America), whereas the PlayStation version is compatible with Konami's own Hyper Blaster light gun peripheral (released in North America as The Justifier). The game's scenery and characters are all 3D polygon models, while most of the enemies and their projectiles are 2D sprites.
