Nier: Automata is an action role-playing game (ARPG) in which players explore an open world. In addition to standard navigation on foot, the game features scenarios with flying mech battles, as well as a special item that can summon wild animals to ride.[1][2] Non-playable characters (NPCs) found throughout the world offer quest objectives, and shops in hub locations sell various items, including consumables that recover health.[2]
Combat uses a real-time action-based hack and slash system, using both light and heavy attacks and combining them into different combination attacks. The player can also evade incoming attacks, gaining invulnerability or counterattack bonuses based on timing. The player is assisted by a flying "Pod" robot which launches customizable ranged attacks varying from simple gunfire to heavy-hitting hammer attacks.[1][3] The first protagonist 2B alternates between two weapons, the second protagonist 9S combines light attacks with hacking into enemies, and the final protagonist A2 can sacrifice health to briefly boost her attack power.[4] There are four classes of weapons available; short swords, long swords, bracers, and spears. Attacks with different weapon types can be charged and launched for increased damage.[1][3]
