About
Undertale Multiplayer is a mod that enables cooperative play in the classic indie RPG, currently running on PC through Steam. The project gained unexpected prominence recently when players discovered they could run the multiplayer mod via Crashphalt, a relatively obscure 2016 platformer that serves as the technical backbone for the experience. This arrangement led to a dramatic surge in Crashphalt's player activity and review count, catching even its original developer off guard. The setup remains functional despite its unconventional nature, with the Crashphalt developer taking the development in stride as community members continue exploring multiplayer options for Undertale.
