NieR:Automata BECOME AS GODS Edition

This achievement can be earned as early as Chapter 5 as 2B. After completing the Amusement Park, you will enter a village chock full of friendly robots. Save beforehand and take them all out until the achievement unlocks. This is also required for an ending under Transcendent Being (15G), in case you want to wait until you are eligible for ending N. It is also worth noting that the friendly village machines will respawn if you kill them and there is no penalty in doing so. As with most achievements, this can be bought in the achievement shop for 50,000 G after completing the game.
