How to make Undertale Fullscreen? [Easy Way!]

Undertale is an independent, 2D role-playing video game released in 2015 by an American indie game developer- Toby Fox. The entire credit for creating this video game goes to Toby fox, except for the artwork and character designs.

This Undertale gameplay got inspiration from several other different sources such as Mario and Luigi, Mother role-playing game series, Brandish, Moon: Remix RPG Adventure, and Mr. Bean – the famous British comedy show.

In actuality, the game was made for 2 hours and planned to be released in mid-2014. However, due to certain complexities, it finally got published for windows in 2015.

Millions of video game lovers loved this game for its intuitive story, characters, dialogues, and easy combat system. Apart from winning the hearts of video game enthusiasts, the game was also nominated for many awards and accolades. It got the status of ‘cult video game’ by numerous publications.  

However, even though the game is truly attractive, there’s no in-game option available to make it fullscreen on the computer (yeah, it might sound strange, but it’s a fact). So, whenever you turn on your PC to play Undertale using Steam, you might feel lost thinking about how to play the game full-screen.  

So, is there any way to play the game full-screen?

There is not only one option but four options available to play Undertale full-screen on your computer, and that too is quite simple.

This post will share the secrets of making Undertale full-screen on a computer using certain keyboard shortcuts. But before that, let’s discuss the plot of this beautiful video game.

The plot of Undertale:

The player playing the game of Undertale is in control of a child who falls into the underground and reaches a secluded area that is separated from the earth’s surface with the help of a magical barrier.

After that, the player meets with Flowey, a sensitive flower who guides him on how to play the game and raise ‘LV’ (love) while gaining EXP (experience) by fighting with and killing underground monsters.

Later, Flowey tries to kill the player for their pleasure before a kind-hearted monster named Toriel stops Flowey from killing the player. After that, Toriel teaches the player about solving puzzles and surviving inside the challenging environment of the underground without killing anybody.

Gradually, Toriel also reveals her intention about adopting the player and keeping him with her for a lifetime to save the player from the monster king of the underground Asgore. This is when the player is involved in a fight with Toriel to set himself free and eventually comes out of control of Toriel.

After that, the player travels the underground to reach the magic barrier situated in the castle of Asgore. During this time, the player learns that the monster king Asgore needs seven human souls to free all the monsters and break the barrier.

Throughout the entire game, the player meets with several different types of monsters – some are violent, and some are not. Some of the monsters whom the player encounters during his stay inside the underground are Sans, Papyrus, Alphys, Mettaton, etc.

The game’s closure depends on how tactfully the player plays the game and proceeds to the next level.

If the player doesn’t kill any monsters or kills some of them while handling others peacefully, he reaches the castle of Asgore. There he learns that not only human souls are needed, but a monster soul is also required to break the barrier, which forces the player to fight with Asgore.

There is also another ending called ‘no mercy’ or’ genocide’ which ensures that the player kills all monsters. Thus, the video game Undertale comes with multiple endings, increasing the game’s attraction.
