Description (written by the developer; not a statement by this register)
[WARNING] be mindful Funny Sans Battle Game is still in beta, A whole lot of intended features are still not in the game yet and a majority of things are subjected to change. FSBG ( Funny Sans Battle Game ) is an Undertale based third person-esque fighting game focused mainly on the character, Sans. This is a game with epic proportions, questionable sense of humor and, most importantly, mortgage payment. This game is best played at a graphics setting above 50%. Type "/challenge (playername)" in chat to challenge someone to a 1v1 •----------=----------• Special thanks to: Up-to-scale tim, Jimmy Jimbleton and all the respective owners of the AUs & theme songs available in the game (you guys rock). Also to Helloburp for inspiring the city map (tprr rocks go play it) This is a fangame of Undertale. All credit goes to Toby "Radiation" Fox & all affiliated members.
