Undertale Yellow is a fan-made prequel to Undertale where you play as Clover, the human with the yellow soul of justice who falls into the Underground. It expands on the original's story with new characters, regions, and music while keeping the same heart, humor, and emotional depth. The game introduces fresh mechanics and creative bullet-hell encounters that honor Toby Fox's style while standing on their own.
