Airbase is one of the original 15 maps in Titanfall.
"The Three Towers" brings the player to Airbase in the seventh mission of the campaign.
IMC reinforcements are about to lift off and crush the Militia fleet approaching Demeter. To even the odds, Sarah leads a surgical attack on the airbase, armed with Bish's new tower-toppling invention, the 'Icepick'. As the battle comes to an end, MacAllan hails Vice Admiral Graves directly on comms, and questions his old friend's efforts to change the IMC from within, but Vice Admiral dismisses MacAllan's remarks and terminates the connection.
