Duke Craft is a combination of DN3D mechanics and Minecraft-like level design. The story is simple - aliens stole Duke's hard earned diamonds and he has to get them back. The map includes some features taken from Minecraft, like crafting or using torches to light the areas. No additional code or sounds were used, only new textures. Don't play it with polymer or else it'll screw up some of the graphics.
