Pray, Retrieve, Repair
NieR: Automata doesn’t feature an auto-save system, so if you happen to die, you’ll respawn at the last access point you interacted with. If you do die, make sure to retrieve your body. Dying in Automata means that you’ll lose all of the chips you had installed at that point in time, and dying again without retrieving it means that those chips will be gone forever. You really don’t want that to happen.
That said, if you’re playing online, you will also stumble across the dead bodies of other players. You’ll have three interaction options: pray, retrieve, and repair. Praying for a dead android will restore your health, retrieving the corpse will grant you money and some temporary combat bonuses, and repairing it will allow the corpse to act as your ally for a short period of time.
Praying is a really handy mechanic in the early game, as it restores your HP completely. If you’re short on HP recovery items, or if you don’t have any chips that help with regeneration, you’re going to want to pray. A lot.
