UNDERSWAP (or TS!UNDERSWAP) by Team Switched is a fangame being developed for the team's interpretation of the popular role-swap AU, Underswap. It is being developed in GameMaker: Studio, and has been in development since March 2016.
This interpretation of Underswap is unique in which the original personalities of each character are kept intact and expanded instead of being swapped.
About the AU
Team Switched's Underswap is an alternate interpretation of the popular AU which preserves the original personalities of the swapped characters and expands on their roles to a great extent.
The fangame itself was created with by the developers with an original experience from the source Undertale game in mind, as well as out of a dissatisfaction for the personality-swapping of characters in the popular interpretation of Underswap.
- The seasonal representation of different locations in Undertale have been changed.
- The Ruins (Autumn) is replaced with Ruined Home (Spring)
- Snowdin (Winter) is replaced with Starlight Isles (Summer)

- Minor details were added to the game based on unused concepts, designs, artwork, sprites, and music by Toby Fox.
