Philadelphia, United States

Philadelphia was the largest city in, a state of the United States of America.

History
In 1943, the, which was located in Philadelphia, was made invisible with the use of a Piece of Eden.

By 1998, Daniel Cross lived in Philadelphia. That year, he was abducted by the Assassin Hannah Mueller and taken to an Assassin camp. The two of them later returned to his apartment, where they were followed by the camp's director, Paul Bellamy. After experiencing a hallucination caused by the Bleeding effect, Daniel attempted to escape from the two Assassins, freerunning over a couple of rooftops.

Two years later, Daniel returned to Philadelphia after he unwittingly killed the Mentor of the Assassin Order. He made his way to Abstergo Industries' Philadelphia facility, where he spent time inside the Animus.

Trivia

 * Developer Ubisoft considered having Philadelphia as a primary location in Assassin's Creed III, but decided against it because the city's grid-like planning would have made freerunning counter-intuitive. The city will, however, appear in a limited, more linear fashion at some point during the game.
