Metro Square is a very large map with many key locations including: a toy store, book store, stock exchange, two ice rinks, an intricate, fully functional subway system, and the Museum of Nature and Science. One major fact about the Museum is if you shoot down the whale display hanging from the ceiling, it will crash through the floor, creating a shortcut to the subway system below. The whale will also serve as a ramp up to the roof where many weapon pickups are available.
