MONO ENGINE is an original game engine that MONOKURO GAMES developed in-house for making its own games. Every MONOKURO GAMES title is made with it.
Mujin Byoto's chapter 1 corridor, open in the MONO ENGINE editorHover to develop
Fog, reflections and glow — enough to draw the air of a horror game.
Film straight from inside the game — trailers and key art alike.
All seven ghosts in Mujin Byoto were built inside the engine. Not a single external 3D model.
The editor is about 151 MB. Drop it in a folder and it runs.
MUJIN BYOTOMONO ENGINE is an in-house tool used only for MONOKURO GAMES' own titles. It isn't sold or distributed — what you'll see of it is the games it makes.
