Robert Mayer Bridge

The Robert Mayer Bridge

Let's confirm the mission.

We've located an armed anti-establishment group's supply line.

The enemy supply convoy will be flying over the Robert Mayer Bridge - stand by in the area, and take down all of their freighters.

We've spotted specialized flight-capable Normals among their fleet, so keep your eyes peeled.

Those are your orders.

Mission Graphic

The player begins the mission atop the Robert Mayer Bridge, and is tasked with intercepting the enemy transport helicopters before they leave the area. The transports have various escorts, such as Normals and attack helicopters, although these do not need to be destroyed to complete the objective.

Part way through the mission, a large armored transport train will pass through the area along the railway under the bridge. The mission ends once the train, and all of the transport helicopters have been destroyed.

Hard mode differences: A Fermi aerial fortress appears after most of the transport helicopters have been destroyed. Destroying it is necessary to complete the mission.
