Description
Do you wanna have a bad time? Now you can with this faithful recreation of the genocide route Sans boss fight from Undertale!

This stage features Sans' full attack sequence as seen in his Undertale boss battle, featuring bones, platforms, gravity changes, more bones, and gaster blasters. Play against a CPU for singleplayer mode, or play with other people and try to survive the longest. Hallway intro, flavour text and Sans' dialogue is included as well for the full genocide route experience.

Choose Basic mode for the original Sans battle, or Aether mode to activate an 'Expert mode', where you have less health and can't heal.

Obtain input codes for each character by beating the boss fight on Standard mode. Input the code with the character at the beginning of the match to unlock Survival mode, where you have 2x HP, but the attacks come immediately one after another. Last until the end to beat this mode.
For starters, Zetterburn's code is: down - up - right - right - left - down - down - up.

NOTE: if you find yourself in a black stage with white floor, make sure you are playing in the latest workshop branch, this stage will not work on older branches.

------------------------------------------
Stage info/mechanics (Mild spoilers below)
------------------------------------------

The menu system has been altered slightly to accomodate for Rivals mechanics. The fight button allows you to attempt to hit Sans with a hitbox. Act will perform a check on Sans, nothing special. Item will make you consume a food item, in a set order. There is a limited amount of food, the Item option will not be available once you run out. Mercy will do nothing up until the Spare section, in which you can press it to activate the spare sequence.

Up to 4 players can play on the stage at once, but any CPU players will be put out of the match, allowing you to play singleplayer.

Press taunt during the opening countdown to activate a text skip mode, where some of the opening and spare dialogue will be skipped, reminiscent of how repeat battles against Sans in Undertale have less text.
