But is their any sort of mods for this game? I was hoping to get more then the small number of scenarios that came with the game and a harder AI to beat. I heard they were making an add on but I have no idea if that is dead or not.

No mods......
I whised they would make the new CapLab modable.

The addon is still in developement. Seems the AI will be improved. (No more emty factories and so on).

Btw. its not an addon, its a stand-alone game.

Ah that sucks since I love having a little substances then just freeplay but thanks for the answer.
