When I apply the air strike power up to a gun or even the Berserker power-up, I can’t see any way that I can activate it while in game. I have tried pressing all of the buttons and it doesn’t seem to do anything. What do you need to do to be able to call in an air strike or use these kinds of power-ups while in game?
It activates automatically when the health of the turret that has the power-up applied to gets low. Not sure the extact trigger for low health is but once it’s low enough it will trigger.
