Birmingham has a problem with rats and rubbish. The city is in the process of collapse. The rats are immune to poison. Houses are taken over by rats, cars are vandalized, rats are attacking other animals and people. The rats are poisonous, if eaten you die, or anything else eats them they die and rot in the rubbish. Fires are all over the city, started either by locals burning rubbish, or rats biting though cables. Toxic smoke is everywhere. Roads are blocked.
