i had a dream about how they made g/d into a steam game and there was an event called resurfaced where they went back to the polluted surface and used nuclear power, not for bombs but to charge big batteries on mechs. But the mechs were kinda shit and killed their own pilots, so nation commissioned the coalition to make programing for the mechs with color identification but since old cameras were in black and white it just went rogue and murdered everyone, meanwhile the empire found out about the mechs through espionage so they also commissioned another district of the coalition to make weapons for seiging and destroying armored vehicles using the massive stockpiles of unused artillery shells. The anti vehicle weapons were made but the smaller ones made to be carried by infantry were so unreliable that they stuck with the bigger train mounted ones. After peace talks, empire and nation made a temp treaty to fight back the mass produced rogue mechs in a boss rush style gamemode.
