In 1911, Ross and Fordham command John to act as a bounty hunter and apprehend his former outlaw friends. To both motivate and ensure that John will comply, the agents kidnap Jack and Abigail, promising their release upon the completion of John's obligations. He works with many individuals throughout the state of New Austin, who help him assault the fort of former gang member Bill Williamson. When Bill flees to Mexico to seek the help of fellow former gang member Javier Escuella, John pursues them. There, John becomes unwillingly entangled in a civil war between rebels and soldiers. He reluctantly works for both sides, only wanting information about Bill and Javier, but disavows the soldiers when they betray him. He eventually locates Javier, and the player can decide whether to kill him or give him to the agents. Bill is also tracked down and killed, either by John or the rebel leader Abraham Reyes.
