Description (written by the developer; not a statement by this register)

Welcome to Undertale Fighting Arena 2. Choose from a variety of fighters, from Gaster Sans to INSANITY! Sans to Fatal Error all the way to ERROR 404. There are 4 stages: The Starter Playables, The Higher Playables, The Anti Void, and then finally the TRUE BARRIER. To get to each level, you must level up SOULs by killing people. If there are any bugs or something you do not particularly like about the game, contact the creator on their communications server with your complaint/report and try to use correct grammar and spelling please.
