The Philadelphia Zoo was once a magical place and one of the greatest tourist attractions in Philadelphia. It housed exotic creatures from around the world, Tigers, Lions, Elephants, Giraffes, Wolves, and dozens of others. After the great war however the creatures sturdy enough to survive the radiation were warped and twisted into horrible creatures and managed to break free from the zoo. The entire district around the Zoo is now home to the insane creatures that have taken the entire district. Colossal mutated bears and Lions with manes of pins stalk the streets around the zoo. Luckily the zoo is across the Schuylkill River and the bridge leading across is heavily guarded by local militia.
