THE ENEMY NEVER STOPS.
NEITHER DO YOU.
The BF faction has launched a relentless air campaign. Bombers, interceptors, attack helicopters — wave after wave, sortie after sortie. You command four anti-aircraft turrets protecting the last standing base. When it falls, it's over.
Tap to fire. Shoot down incoming aircraft before they release their payload. Intercept bombs mid-air for bonus points. Survive long enough and you'll earn air strikes of your own. Reach sortie 20 and something unusual has been spotted in restricted airspace.
