Undertale RNG is a rolling game where you spin for custom auras inspired by Undertale and Deltarune, then complete missions, craft gear, and use aura abilities. Only one tracker currently maintains a fresh list for this game, so no code can be confirmed by two sources right now — the current Halloween codes are listed as worth trying below and are dated to expire on November 5.
