Blazer/Mission 8

Once Vanguard's fuel meter has been emptied for the third time in the game, Maiheriko will rise into the air, then start moving forward of its own accord for a third time, as four Boeings come flying towards it from behind; once you have moved out of their way and fired a bullet at each of them to kill them (but if you don't kill them off immediately, they will turn around and fly back towards you), three more Boeings and an Ivory Heli will come flying towards you. Once you have fired bullet at each of them to kill them, two more Boeings and another Ivory Heli will come flying towards you - and once you have fired a bullet at each of them to kill them, two more Boeings and a third Ivory Heli will come flying towards you. Once you have fired off bullet at each of them to kill them, four more Boeings and a fourth Ivory Heli will come flying towards you - and once you have fired a bullet at each of these, to kill them, Maiheriko will descend down to its third, and final, landing pad (where Vanguard has reappeared in its normal shot incarnation for a third and final time) as the latter's fuel meter is refilled (Maiheriko's rotor will also once again momentarily disappear at this point), before it starts to move forward yet again.
