The Player, also known as god, is the secondary protagonist of OneShot. Out-of-universe, they are the player moving Niko; in-universe, they are the god of the World, tasked with guiding Niko through it and saving them along with the World in one shot. The Player's name is by default the username on your PC, but this can be changed when Niko asks the player's name when they first contact the player.

Based on in-game dialogue and options, The Player is equally as determined as Niko to save the world. They often lend Niko their aid in puzzle solving and deciding what action to take next, acting as an adviser or strategist to Niko.

The Player has proven themselves to be very resourceful, as they are able to improvise solutions and plan for the future on-the-fly. It is implied that The Player is solely managing Niko's inventory (as Niko will remark on The Player's inventory decisions), demonstrating that The Player is able to combine and repurpose countless items to suit the cause, speeding Niko's progress through the world.

The Player is known to easily collapse under guilt, as they are completely unable to hide the truth about The Sun from Niko, even if the out-of-universe user deliberately chooses the "keep quiet" options. The World Machine even taunts The Player for their immense care for Niko by saying "You might as well tell Niko the truth. You do care about Niko, don't you?".

As evidenced by The Player's in-game title being "god" and not "God", The Player has several abilities beyond the boundaries of the game but is neither omnipotent nor omniscient. This is referenced at least once at the end of the game when The Player learns the truth about The Sun for the first time, and admits to Niko that they don't know what will happen to them.
