Not the full game, no. Undertale is a paid title on major storefronts, but there is a free official demo you can download to sample the game before buying: official Undertale demo. Do note that the demo’s save data will not transfer to the full game if you later purchase it. For the full experience, you’ll need to buy the game; on Steam it’s listed at $9.99, and GOG offers the same base price as well: Undertale on Steam and Undertale on GOG. From time to time, Undertale also goes on deep sale—in 2025 there was a Steam promotion dropping the price to around $1, which spurred a large spike in players: GamesRadar coverage of the sale.
