Looks like hacking really did the trick for this boy.
Compare how he was utterly clueless how to operate this monster at first but now..
This actually seems like the only thing he can do in this situation. He has to finish them all off before emegency power goes offline. If he's still in the air by that, he done for. So he really got to hurry actually.
That beeing said, i wonder how the missiles are guided? Is the body heat of the DEs enough to track them? Or is the suit coordination the movements(adjustments to counter evasion attemts)?
I fear this joyride will be over soon, not just because of the energy problem, also because he wont have much missiles left after that.
