About Us

Sans is one of the main heroes in Undertale and everyone’s favorite monster. It’s hard not to feel sympathy for this kind-hearted skeleton who believes in justice, peace and love. In this fighting simulator based on Undertale, you will be able to play as Sans fighting against Frisk who has gone evil and chose to kill rather than to rescue!

Guide Sans into the battle!

You’ll have a bunch of special tricks at your disposal that you can use against your enemy. Since Sans is a skeleton, they all have something to do with bones. You can throw and shoot bones, use them as a shield or even to set up traps for Fisk. In the process, you will be able to increase your level and improve your parameters which will come in handy since Fisk will start already from the highest level. Enjoy this great battle simulator on Fun Site!
