Undertale

Welcome to a thrilling game, where you will become a little girl who occasionally found herself in the underworld. This place is full of all kinds of monsters who were trapped here after they lost a war to humans. You will have to both fight the monsters and try to make friends with them. Multiple tests, traps and other adventures await you here. And the most important this is to take the final decision in the end of the game - to defeat the monsters completely or give them a chance for a new life.
