He will use it to block your attacks and it will become more difficult to deal any damage to him. You will see a giant bone that will appear in his hand. If you proceed to the second phase, Sans will get more frantic. This is the first choice you need to make – whether to hit Sans or spare him. In the process, the skeleton will also try to reason with you talking about how different his life could have been if not for you and asking why you keep killing everyone. Basically, it’s just a little bit enhanced version of the Sans you remember from Undertale. The first won’t be very complicated since your opponent looks like Sans and uses attacks that aren’t very different from his original capabilities. For your part, you will be playing as Frisk and it will be your choice whether to keep your genocide crusade or see that you’re doing it wrong and change your mind! Sans vs Frisk – who is going to win? And Undertale Last Breathe is yet another one of them you just can’t miss! Here you will play against Sans eager to confront Frisk who has taken up the path of evil and stop him from ruining the monster world. There are plenty of fan-made games created on the base of Undertale.
