Marmoset is 8monkey’s proprietary game engine and tool set which have been in development for the last three years for Darkest of Days . Marmoset provides all the capabilities of a modern, full-featured 3D engine in a simple light-weight package. Originally developed on Windows PCs, the engine has recently been ported to the Xbox 360. 8monkey is always on the lookout for new opportunities to utilize the Marmoset technology.
