InfoUnderground Location is an Undertale AU created by GoldenDust66. It is mainly based off of FNaF: Sister Location with some elements from the other FNaF games.
Michael Afton takes the Player/Protagonist Role. He goes down to the Underground via elevator. When he gets down there, the elevator breaks. Now, he must choose a path. Either go Pacifist to free them all, or turn them all to scrap metal.
Rainbow takes the Empty One Role. She tries to trick Michael with 'friendliness pellets', which are actually harmful bullets.
HandUnit takes the Caretaker Role. He guides you through the [RUINS]. Instead of fireballs, he uses electric shocks.
