Crypt Killer (known as Henry Explorers in Japan) (ヘンリーエクスプローラーズ Henrī Ekusupurōrāzu) is an arcade video game produced by Konami. The players are "crypt raiders" guided by Galazon, the spirit of travels, who resembles a floating head to travel through variously themed caves, temples and crypts in search of the "Eyes of Guidance" which would open the doors of fate. On their journey they are armed with a shotgun to fend off many mythical enemies, such as mummies, skeletons, fish-men, Gargoyles, and an array of other monsters.
