Nier: Automata shares the post-apocalyptic setting of the original Nier, taking place after the game's fourth ending.[6] While carrying over the Drakengard series' tradition of a dark atmosphere and branching storylines, no direct narrative connection is shared between Nier: Automata and the rest of the series.[7][6][8] Set in the year 11945 AD, the story revolves around a proxy war between the human-made androids and the machine army of invaders from another world.[9][10] Lacking both emotions and true names, androids have particular attitudes that distinguish them from their fellows.[9][10][11] The "YoRHa" android forces are commanded from the Bunker, a reconnaissance base in orbit above Earth. They fight alongside the pre-YoRHa androids on Earth (known as the resistance) to drive back the Machines.[12]
