Why should Spidertron have 8 legs? You can customize the number with this mod (affects ALL spidertrons). IMPORTANT: Due to a base game bug, Factorio will crash if you change this and then load a save that already has a spidertron on the ground. To work around it for now: Pick up your spidertron(s), save, change this value in mod settings and restart game, and put them back down.
Small changes concerning balance, gameplay, or graphics.
