The Tournament

The Tournament was a virtual representation of one of Ratonhnhaké:ton's genetic memories, relived by Desmond Miles in 2012 through the Animus.

Description
Connor fought other contenders to win the Boston Brawlers Tournament. First he fought the Redcoat and his three sidekicks. After he was beaten, he was given a sword, but despite his cheating, Connor defeated him.

Next, Connor fought the Docker. He could counter his blows by throwing him, and hit him after breaking his defense. However, the audience began to interfere, shoving him if he got too close.

Connor was poisoned by his next opponent, the Surgeon, but defeated him and his sidekicks before he was rendered unconscious. His final opponent was the Huntress, who cheated whenever she began to lose by having an identical accomplice step in with a smoke bomb and replace her. Regardless, Connor beat both women and declared the new champion.
