NieR:Automata BECOME AS GODS Edition

You will first meet Emil on your way to the Forest Castle. He is a friendly little machine head that will roll past you and out of the shopping mall. After completing the castle, you can find Emil driving around in the City Ruins. He is easy to spot because his shop plays music as he rolls around. His face will also show up on the mini map while you are in the City Ruins. Smack him with your sword to get him to stop and you will be able to see his wares and earn this achievement. As with most achievements, this can be bought in the achievement shop for 50,000 G after completing the game.
