NieR:Automata BECOME AS GODS Edition

As you progress through the story, you will have several encounters in a flight unit as either 2B or 9S. These encounters are in the form of shmup sections. This achievement should come naturally as long as you shoot everything you see and do not actively avoid enemies. Should you somehow miss it, this achievement can be purchased from the Achievement Shop for 100,000 G after completing the game.
