Rush is a game mode in Battlefield 1.
Communications and artillery were crucial during World War I, and Rush mode will have you interacting with both of them. In Rush, the Attacking forces must find and destroy the Defending force’s Telegraph Posts, which the defenders can use to call in artillery strikes. The Defenders can deny the Attackers by disarming the explosives they plant, but should the Telegraph Posts be destroyed, the Defenders must fall back to another sector. The Attackers win the battle if the Telegraph Positions in every sector are destroyed. The Defenders come out victorious if they’re able to run the Attackers out of reinforcements, or by having at least one Telegraph Position left intact when time runs out.
