Undertale Soundtrack: Undertale is a 2015 2D role-playing video game created by American independent developer Toby Fox. The game is set in the Underground, a large, secluded area beneath the Earth’s surface, separated from the human world by a magical barrier. The player controls a child who has fallen into the depths and travels back to the surface while encountering various monsters.
The combat system involves the player navigating through mini-bullet hell attacks by the opponent. The player can opt to pacify or subdue monsters in order to spare them instead of killing them. These choices affect the game, with the dialogue, characters, and story changing based on outcomes.
