First WWF PPV appearance for Shawn Stasiak since Survivor Series 1999.
This event marked the first time WCW, ECW, and WWF (now WWE) shared a pay-per-view. Although the WCW/ECW Alliance would participate in several WWF events for months after Invasion, they never shared billing after this event.
Prior to the Invasion storyline, the July PPV event was titled Fully Loaded, which would help build story lines until SummerSlam. However, as a result of the ongoing Invasion storyline, which would have seen a resurgent WCW and/or ECW promotions under the auspices of WWF should it be a success, the July PPV was renamed Invasion by Linda McMahon, with the idea that every match on the card would have WWF wrestlers take on members of the WCW/ECW Alliance.
Whilst he gave a sit down powerbomb to X-Pac, Billy Kidman actually suffered a knee injury whilst performing the move which would keep him out of action for approximately 3 months.
First WWF PPV appearance for Sean O'Haire, and his final one until Backlash 2003.
