Battlefield 3 multiplayer is set to add "Air Superiority" mode with the upcoming Endgame DLC.
As spotted on NeoGaf, this brings dropships to the game for the first time. Troop transport can be air dropped into battle, allowing the dynamic of each encounter to dramatically change.
This DLC will also include four new maps, three new vehicles (including dirt bikes), and a return for Capture the Flag. Head on over here for more details.
