This is… interesting. The battleground is past the half way point for each robot. In theory, the robot armies won't have enough power to get to the others' factory. Very picturesque if you want to show robots are a danger without losing infrastructure.
However, each army is only twenty percent of the available robots. Sixty percent of the robots went inert before the armies left. Three extra packs per robot, they'll have plenty of power to reach the others' factory.
Whoever set up this little war. I'm afraid we must cheat them out of a very expensive learning experience.
