Operation Métro was the first multiplayer map revealed for Battlefield 3 and was playable in Rush mode at the E3 show 2011. Ever since, it's been one of the defining experiences for Battlefield 3.
In Rush a team of attackers is tasked with arming and detonating pairs of M-COM stations in sequence, progression through new areas of the map as they do so. For the defenders, the mission is clear: Prevent the attackers from detonating every M-COM or lose the game. For the defenders, the only way to win is to deplete the attackers’ respawn tickets (defenders have an unlimited amount of these).
With that, we will leave you to it. Just make sure to arm and disarm a lot of M-COM stations this weekend, and we will get back to you next week with the results.
