Bots are crashing into each other, piles of them need to be serviced, assemblers need to be fixed, and there's wildfires destroying all the trees. The aliens will be here soon. Oh, and our oil refinery blew up. Please don't shoot the messenger...

To decrease difficulty, turn on the optional fire extinguisher and/or water turret mods. Probably turn off exploding trees, wildfire season, and belt overflow as well.
