Sans Simulator

A free-to-play fighting game created by fans called Sans Simulator. It is based on the well-known game Undertale. Players assume control of Sans for the fabled last stand as they attempt to eliminate the human character.

What are the features of the game?

The cult classic’s peculiar and sometimes peculiar humor, branching plotlines, and several endings left a lasting effect on fans. In one game’s finale, the player faces off against Sans in one of the game’s most brutal battles while evading unavoidable explosives.
The hero encounters several foes and allies throughout his explorations of the vast Undertale tunnels. And just as in the real world, the player’s actions — be they friendly or aggressive—determined how they interacted with these humans and creatures. However, the connection did not work out right away with Sans, one of the most formidable warriors in the underground, so you had to battle him. There is, however, always room for discussion.

New additions to an old favorite game

Sans Simulator flips the conflict such that the player is attempting to win against the human character. To try and reduce the opposing player’s heart rating to zero and ultimately win, they unleash a variety of explosives and attacks. One player controls each character in the game’s local cooperative mode.
Even though it’s a short and enjoyable game, fans of the series will likely find more interest in it because there isn’t any substantial character development or extra material.
