I have taken the liberty of writing the entire script of UNDERTALE. Written in British English. I have looked around and I can only find certain sections but I am writing the entire transcript of the game into a word document. This may be a massive text dump or it may be separated into chapters. I am not sure on which. For now, it will be separated into different places/battles. This will include all phone calls at the end of the game, the major routes (Pacifist, Genocide), and maybe a few neutral routes.

Here are some determination quotes from Undertale found from save points.
