”Long time ago, two races ruled over the Earth: the Humans and the Monsters.
One day, a war broke out between the two races. After a long battle, the humans were victorious. They imprisoned the monsters under a mountain with a magic spell.
Many years later…legends say that those who will climb the mountain will never return.”
This is the introduction of Undertale created by Toby Fox. It’s a role-play game.The Players control a human child who has climbed the mountain and fallen into the Underground, a large, secluded region underneath the surface of the Earth, separated by a magic barrier. The human interacts with many monsters while on a quest to return to the surface.
When players encounter enemies, they enter in a battle mode. During battles, players control a small red heart which represents their soul, and must avoid attacks. The player can fight, act or mercy the monster.
