Dysis is a voxel-based RTS with robots, modding support
It’s the fate of every game with voxels and terrain deformation to be immediately compared to Minecraft, but Dysis is one of the few to take an entirely different tack, combining real-time strategy with first-person shooting, base building with a splash of tower defence, and robots with… other types of robots. Sole Developer Chris Farrell makes real robots for a living, so expect this element to be fairly well researched.
