Sekiro: Resurrection refers to the ability in Sekiro: Shadows Die Twice of the player to choose to resurrect on the spot if they die, rather than restarting from the last checkpoint. This ability is only available once per checkpoint unless the player recharges the ability by killing enemies and performing Shinobi Deathblows.
