The environment has become more like a jungle. Armor wearing gorillas police in the city, and humans are kept as slaves if they break any rules made by the ape overlords.
All the famous landmarks, in this transformation, has turned into ape versions, including Mount Rushmore in South Dakota, Golden Gate Bridge in San Francisco, Lincoln Memorial in Washington D.C, Statue of Liberty in New York, Sphinx of Egypt, Eiffel Tower in Paris, France, and even Big Ben in London, U.K. (Great Britain).
