Payload Race maps feature both RED and BLU teams issued with a cart; Neither team is restricted to an attacking or defending role, with both teams assuming characteristics of both roles.
To win, each team must simultaneously push their cart through enemy territory to reach the final point while preventing the enemy team from doing the same.
As with Payload mode, team members push the cart by standing next to it, with more members increasing the speed of the cart and opposing team members halting it.
Unlike Payload mode, the cart will not move backwards after any duration of time and there is no time limit; the map will only end when one team successfully pushes their cart to the finishing point.
Each cart works as a level 1 Dispenser for their team (and disguised enemy Spies), restoring health and ammunition to those pushing the cart.
Parts of the track may feature slopes on which the cart will quickly roll back down to the bottom unless it is being constantly pushed.
Payload Race maps may or may not be split into multiple rounds.
