About the game
A beloved indie RPG in which you fall into an underground world of monsters and decide for yourself whether to fight or befriend everyone you meet. Its clever bullet-dodging combat, sharp humor and unforgettable soundtrack made it an indie landmark.
Did you know?
Undertale was created almost entirely by one person, Toby Fox, who also composed its entire soundtrack.

These are not ordinary keys. A gift is usually region-locked and arrives through someone else's account — if the region does not match, the game will not activate. An account means you get someone else's login: the game never becomes yours, and it breaks Steam's rules. A DLC or a bundle is not the base game. That is why none of them count towards the price at the top of the page.

The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.
