TS!Underswap (stylized as TS!UNDERSWAP), or Team Switched's Underswap, is an UNDERTALE fangame created by Team Switched for their interpretation of the popular role-swap AU, Underswap. It publicly began development on February 16, 2016 [1] using GameMaker: Studio, and now uses GameMaker: Studio 2 since late 2019.

On December 23, 2020, the first demo was released which features the first area, Ruined Home.

Characters' roles have been swapped in pairs, much like Underswap. However, this interpretation preserves the original personalities of each character, while expanding upon their roles to a great extent.

While the fangame was originally based on classic Underswap, the team gradually developed a dissatisfaction for the modified personalities of the swapped characters. In order to accurately portray the characters in their new roles, the team decided to develop a much more original interpretation.

Gameplay

TS!Underswap plays identical to UNDERTALE, where the player controls a human as they navigate through the Underground. In the overworld segments, there are various puzzles, interactable encounters, and newly-added overworld dodging mechanics inspired by those of DELTARUNE. Battle segments consist of a bullet hell format, where the player must control a SOUL to dodge monsters' attack patterns.

Notable Changes

General

  • Minor details have been added to the game based on unused content from Toby Fox's UNDERTALE (including scrapped concepts, designs, artwork, sprites, and music.)

  • Spep is the mascot of Team Switched and appears alongside the Annoying Dogs for shenanigans. His catchphrase is "Put some pep in your step!".

Locations

In order to create "new" areas, the seasons corresponding to each major location of Undertale have been swapped, and brand new sub-locations have been created. Locations include:

  • Ruined Home (Spring) replaces The Ruins (Autumn)
    • The Sewer is a brand new area which contains an "entirely new event sequence" [9] in which Chara must dodge leaks of boiling water and later survive an intense overworld attack from the mad dummy.
    • The City of Old is another brand new area, containing various shops and miscellaneous activities. [10]
  • Starlight Isles (Summer) replaces Snowdin (Winter)
  • Crystal Springs (Autumn) replaces Waterfall (Spring)
  • Boreal Bluffs (Winter) replaces Hotland (Summer)
  • The NEXUS replaces The CORE
  • The City of New replaces New Home

Game Mechanics

  • Minor improvements to UNDERTALE's game mechanics (DELTARUNE-inspired inventory system and overworld dodging mechanics.)
  • Brand new accessibility options (official translations, screen resolution, optional aesthetic borders, configurable controls, volume sliders, low VFX settings, and more.)[11]
  • The Journal is a new addition which provides a record of all characters, locations, and quests encountered.
  • Various side-quests will be present throughout the game. They will not be important to the plot, and instead offer additional lore and unique reward items. These are usually menial tasks like bringing a plant water.

Trivia

  • Due to characters retaining their personalities, and their actions affecting the world around them, roles are handled very differently from traditional Undertale AUs.
    • Many characters are present in areas their counterparts were not in Undertale--for instance, Bugerpant appears in Ruined Home, while Nice Cream Guy doesn't appear until Snowdin.
    • The roles themselves are handled quite differently for both major and minor characters. This will result in the plot progression of TS!Underswap greatly diverging from Undertale's, with entirely new event sequences.
  • Prior to its major reboot phase, each of the locations of TS!Underswap had names "opposite" of Undertale's--for instance, "Sunnedout" (now Starlight Isles) and "Snowdin", as well as "Coldsea" (now Boreal Bluffs) and "Hotland."
    • An official name was never completely given, or decided on, for TS!Underswap's Waterfall replacement prior to its major reboot phase--currently, it has been named "Crystal Springs."
    • Coldsea was the last of the location names to be updated, having been changed in late November 2019 for consistency reasons. The new name reflects the intended geographical features.
  • Sans had been redesigned many times.
    • His first major design resembles classic Underswap Sans.
    • His second major design resembled his first, but had some differences--a white "X" replacing the Starman symbol, black athletic shorts with white stripes, and a torn space-themed blanket as a cape.
      • Like how the Starman symbol on Papyrus's battle body in Undertale references EarthBound, the "X" on this design iteration referenced the game "OFF" by Mortis Ghost.
    • His third major design was a complete overhaul, sporting a blue mask, cape, and jacket.
    • His fourth and final major design is a modified iteration of the previous one--most notably, his jacket is replaced with a blue hoodie emblazoned with a white crossbones, hence his secret identity's name.
  • Asgore enjoys drinking tea, tending to the flora in Ruined Home, and playing classical guitar.
  • Papyrus does not smoke in Team Switched's Underswap. His original design's cigarette was replaced with a lollipop --- it was inspired by this video, beginning as a joke but then becoming part of the goofy skeleton's character.
  • Papyrus's hoodie is suppose to resemble his battle body. It takes hefty inspiration from a piece of art by Tumblr user lead-namari. [12]
  • Papyrus used to work as a scientist along with Undyne and her predecessor.
  • Sans cannot change the shape of his pupils, contrary to popular interpretation. Though, he did find a pair of star-shaped glasses in the dump one time. This is a reference to the fact that the popular headcanon, cutesy version of classic Underswap Sans, Blueberry, is shown with star shaped eyes.
  • Sans has the ability to use "shortcuts" like his Undertale counterpart. This allows him to perform seemingly-impossible pranks on Papyrus and his other friends.
  • The name "Mettacrit" is the headcanon name given to Mettaton's ghost form in the Storyshift AU. This name is used as the canon name in Team Switched's Underswap.
  • Team Switched's Underswap is perhaps the oldest of all swap takes, having been around since, at the latest, June 14th, 2016.
    • While entirely speculation, it seems that TS!Underswap's transition to a more original project sparked the frequency of unique Underswap takes in the community.
  • Team Switched and the creator of Inverted Fate, Dorked, are on friendly terms with one another. Team Switched has promoted Inverted Fate content (playable battle adaptations, video animations, etc.) via their social media.
    • Dorked has repeatedly stated that TS!Underswap and Inverted Fate are two entirely separate projects, with neither copying from one another.[13]
  • Dorked has made a playthrough of the April Fools 2019 joke demo, Team AAA Underswap (also known as Underswaaap), on YouTube.[14]
