Endings

The following information lists all of the endings that can be found in OneShot.

Return the sun
If the Player chooses the option "Return the sun", Niko responds that the Player is right, that they just can't leave all of the inhabitants of the World to die, thanks the Player for their help and promises that they'll be okay. They place the lightbulb onto the spire. This scene is followed afterwards the closing credits of the game in white background and black text as well as images of the residents of the World witnessing the return of their sun. In this ending, the World's sun has been restored but Niko does not return to their home world, as they did not shatter the lightbulb, which was their only way to return home.

If the Player attempts the reopen the game after choosing this ending, they will find the title screen's background white and its text black. Upon choosing "start", the game opens to the room where Niko found themselves in at the beginning of the game empty at brightly lit with light coming from the World's sun.

Return home
If the Player chooses the option "Return home", the screen cuts to black and Niko responds that they trust the Player's judgement. A shattering sound effect can be heard, indicating that Niko has shattered the lightbulb, accompanied by the shaking of the game window. The screen then cuts to the part where Niko finds themselves in darkness. They ask the Player what happened and comments that it is very dark. Afterwards, they exclaim that they see a light at the end of the passage and that they hear the voice of their mother calling them. They walk forward and explain that all they need to do is pass through the wall and they'll be finally home again. They bid goodbye to the Player and thanks them before walking out of the game window. Afterwards, the closing credits of the game appear but in a black background and white text. In the 2016 remake, the World immediately ends when this ending is chosen. A popup window with "Fatal Error" as its title then appears with the message, "The savior is gone. All hope for the world is lost.".

If the Player attempts to reopen the game after choosing this ending, the same popup window appears and the game doesn't open.

Quitting the game
There is an another ending that will only occur if the Player chooses to quit the game. Upon opening the game after quitting, the Player will that the title screen has gone dark, the lightbulb in the word "OneShot" has shattered and Niko is no longer displayed in the game. Instead, only their scarf and their hat are the only things that remain in place of Niko. When the Player selects "start", the room where Niko found themselves in at the beginning of the game is dark and empty. When the Player attempts to close the game, a popup window appears with a message (presumably from the Entity) that says, "You killed Niko.".

This ending is considered to be the worst.
