During the war between Yellow and Red in another country, the Blue Empire and the Green Republic we're both in a political argument, both sides were allied with each other. Blue wanted to support Red, but Green wanted to support Yellow. After the argument, Green declined all shipments of materials (i.g metal, steel) which made Blue's famous engineering decrease dramatically. The Blue's hierarchs decided to stop giving oil, due to this, Green's transportation dropped. Since Blue and Green had a partnership over there land, Blue invaded and stole most of Green's land was Blue's. Countering this, Green made several tunnels, so they could easily travel from one place to another undetected. This operation caused most of Green's success to take over there land. Blue later found out of this plan and later ambushed them. As the war raged on between Blue and Green, Blue burned down most of Green's farmlands, causing Green's people to starve. Green countered by doing the same. Blue has vehicles, but not much due to not recieving metal, Green has missiles, but without oil, they can't fire them. The war keeps going, traveling over the country of the United Northen Colours.
