10 minutes. 5 gamemodes. 1 winner.
It's called the Pentathlon.
Every 2 minutes to objective changes on the fly. There are no rounds just one seamless transition from one gamemode to the next. You start with basic TDM and the team with the most kills at the end of the round gets a point. If both teams have the same number of kills then no point it awarded. Next is Capture the Flag followed by Kill Confirmed, and Domination with points being given to the winner or no points awarded in the event of a tie.
The final round is a no respawn version of TDM. This game serves as the ultimate tie breaker.
