A Grudge Match is a race type in the career mode of ModNation Racers and ModNation Racers for the PlayStation Portable involving a player's Mod and the Elite Mod of a particular track. They do not not appear in the Career Mode of ModNation Racers: Road Trip, as it is based off a tournament system instead of the story-based gameplay of the other versions of the game.
There are three types of Grudge Matches:
- Get Higher Score Than Your Opponent, in which the objective is to outscore the opponent by performing drifts and spins throughout the track for the duration of the race.
- Finish 1st, in which the player races against the Elite Mod and up to six of their thugs for first position. The number of thugs will be more than 6, in some cases.
- Beat Your Opponent on 1-on-1, in which the player races against the Elite Mod for first position. (There is only one in the PSP Version).
On either type of Grudge Match, victory will unlock that Elite Mod, their Kart and specific build parts for use outside Career Mode.
