Dezaemon 3D

About

Dezaemon 3D is a Nintendo 64 shooter that doubles as a level-building tool. Released in 1998 for Japan-only, it lets players design first-person shooter stages with custom enemies, layouts, and music. The game itself acts as both a playable title and a sandbox for creating new challenges. Players can tweak details like enemy behavior and level geometry, then test their creations in solo runs. The editor mirrors the gameplay loop closely, making it easy to jump between designing and shooting. What stands out is the sheer flexibility of the editor. It offers deep customization without requiring coding, letting users shape everything from bullet patterns to boss designs. The game was paired with an unreleased 64DD expansion disc, hinting at untapped potential. Though largely forgotten outside niche circles, its blend of creation and action remains ahead of its time. The Japan-exclusive status and 1998 release date make it a rare artifact of early 3D game design.
