Welcome to UNDERTALE. In this RPG, you control a human who falls underground into the world of monsters. Now you must find your way out... or stay trapped forever. ((Healthy Dog's Warning: Game contains imagery that may be harmful to players with photosensitive epilepsy or similar condition.)) features: • Killing is unnecessary: negotiate out of danger using the unique battle system. • Time your attacks for extra damage, then dodge enemy attacks in a style reminiscent of top-down shooters. • Original art and soundtrack brimming with personality. • Soulful, character-rich story with an emphasis on humor. • Created mostly by one person. • Become friends with all of the bosses! • At least 5 dogs. • You can date a skeleton. • Hmmm... now there are 6 dogs...? • Maybe you won't want to date the skeleton. • I thought I found a 7th dog, but it was actually just the 3rd dog. • If you play this game, can you count the dogs for me...? I'm not good at it.

Where to buy Undertale cheap
Undertale launched at $9.99 in 2015. On the canonical US/USD baseline, the lowest confirmed-unrestricted total is $8.27 at Kinguin, which is 17% off the recommended price.
On that same baseline, official stores start at $9.99, so the keyshop route saves $1.72 on this title. That saving comes with a trade-off: keyshop listings are resold keys, and a listing marked as a gift is not a standard key. The key type column above tells you which is which.
Feed update times differ by store. Confirm the current price, product type and activation region on the store page before completing the purchase. Our comparison methodology explains matching, ranking and checkout-fee limitations.
