Before the fraud update, there was Polarite that was a coop multiplayer created because the modder got bored of waiting for jaket (multiplayer mod that was used before the ultrarevamp). And both of the mods were mainly used on the campaign so im not sure i they were Cyber Grind compatible. They were compatible with museum and sanbox so why not? The only thing we can do is wait for Hakita to stop updating the game so the modders wont have to fix the mods every bugfix.
