Now that Andross has no hands left for you to destroy, you’ll be taking on his head. Again, use ZL to lock on and focus all of your firepower on the inside of his mouth, which, of course, can only be hit when his mouth is open. Andross has a couple of moves he will use during this stage, the first of which is spitting chunks of debris at you. It’s at this point that you’ll get most of your damage in. Simply continue to fire at the weak spot as you dodge from side to side, avoiding the incoming projectiles.
Andross may also perform a head charge. You’ll be able to read this coming a mile off as his head will stay still briefly, before charging forward toward you. Dodge out of the way as you see the head stay still to avoid taking some hefty damage.
The final move that Andross will use against you is a beam that he fires around the room at you. This beam will come at you at different heights and so you’ll need to either hover above it or drop back to the ground as you see it rising.
