Deltarune is one of the best single-player couch games out there, especially when someone is going in blind. However, there isn’t an official way for multiple players to play through Kris and the Fun Gang’s journey at the same time. Now, thanks to a team of talented modders, up to three players can experience the game as a co-op RPG.
The Deltarune Local Multiplayer mod was developed by a team led by Yomsmam. Rather than give all three players the chance to control Kris, Susie, Ralsei, or any of their guest party members in the overworld, it restricts multiplayer to combat and minigames. When either of these comes up, the other two players get to jump in.
