"I say this to you with the unvarnished factualism of plain talk: I love Arena Mode."
Abraham Lincoln, Second Inaugural Address, 1865

Arena is a game mode added during the Heavy Update in which teams RED and BLU are pitted against each other, in a battle to the death. The goal for both teams is to kill all of the opposing team's players, with no respawning during rounds. If both teams survive one minute of fighting, a control point will unlock, allowing a team to win by capping the point.
