The window resists the first couple starbolts, but your third shatters it open- but not before six laser turrets whir to life.

Three of their opening volleys go wide, but two train on the brightest glowing target and open fire. Moving by instinct, Starfire manages to dodge them both.

As for the sixth... maybe the three of you were too preoccupied with the rising of the fortress, but Professor Bravo attempted to make that opportunity to escape. Trained on his hastily retreating back, the final turret converts him to a fine mist.
