The Undertale: Undertale Together Mod is a free add-on that brings co-operative play to Undertale.

Play Undertale with a friend

Undertale and its sequel Undertale: Underfell picked up plenty of fans throughout the world, but some players found themselves wishing that the Undertale experience had come with a two-player option. The Undertale: Undertale Together mod aims to fill this gap in the original game. By installing the mod, you will be able to play through Undertale as a two-player game.

Play online or offline

The two-player mode that this mod brings to Undertale can be played both online and offline. In offline mode, each player uses a different half of the keyboard, and it is also possible to use a joystick. Setting up online play is more complex, and may require installing new software or disabling antivirus and firewall programs.

A new angle on Undertale

While Undertale was a popular hit and made a vast number of players fall in love with its characters, world, and storyline, the lack of a two-player mode meant that exploring that world could be a lonely experience. However, by installing the Undertale: Undertale Together Mod, you can experience an entirely new dimension to the game. With two players making their way through the game's world, this old favorite takes on new life.

A treat for newcomers and old fans alike

Whether you are an experienced Undertale player who wants to see the game with fresh eyes or a complete newcomer to Undertale, the Undertale: Undertale Together Mod has plenty to offer. The gameplay and storyline that made the original Undertale a hit remains intact; but now, you will not need to play it alone.
