Most online multiplayer challenges in a videogame

Burnout Paradise allows players to jump in and out of friends’ cities at any point. Up to eight players can drive around Paradise City at once and there are 50 multiplayer challenges to be completed as they do so. As every group combination has its own set of 50 challenges, the game’s total number of multiplayer tasks stands at 350, which is the highest number of any racing game.
