The main event was a Triple Threat match between Stone Cold Steve Austin, The Undertaker and Kane for the WWF Championship, which ended in controversy when The Undertaker and Kane simultaneously pinned Austin. Another match at the event was a Triple Threat match in a steel cage between Ken Shamrock, Mankind and The Rock to determine the number-one contender to the WWF Championship.

The event featured twelve professional wrestling matches with outcomes predetermined by WWF script writers. The matches featured wrestlers portraying their characters in planned storylines that took place before, during and after the event.

The main feud heading into the event was between Stone Cold Steve Austin and Vince McMahon, who did not want Austin as the WWF Champion. McMahon originally seemed to be against The Undertaker and Kane when he insulted them on the September 5 episode of Raw Saturday Night (taped on August 31 but not aired until Saturday because of US Open (tennis) coverage on the USA Network). On the September 6 episode of Sunday Night Heat, however, McMahon apologized for his comments and revealed that Austin would defend his title at Breakdown in a Triple Threat match against The Undertaker and Kane. On the September 14 episode of Raw is War, McMahon added a stipulation where The Undertaker and Kane cannot pin each other. McMahon then got in Austin's face, and Austin began to attack McMahon until The Undertaker and Kane attacked Austin. Later that night, during Austin's match with Ken Shamrock, The Undertaker and Kane interfered. The Rock and Mankind also came down. They fought off The Undertaker and Kane as McMahon looked on from the entrance ramp. Austin hit The Undertaker and Kane with a steel chair and chased McMahon. On the September 21 episode of Raw is War, The Undertaker and Kane defeated Austin and Billy Gunn. After the match, Austin hit The Undertaker and Kane with a chair.
