The indie RPG Undertale is getting physical copies on Nintendo Switch, including a hefty collector's edition loaded with goodies for fans. An Eshop release is also planned for release in September, and Fangamer is putting Undertale merchandise on sale throughout August in the lead-up to launch.

An Undertale standard physical edition for Switch will be $29 and come with a 24-page story booklet. It will be sold online through Fangamer and at Best Buy retail stores. A separate collector's edition will be $69 and available only through the Fangamer site. That one includes the game and art booklet, along with a 14k gold-plated brass music box locket, a 2-disc soundtrack CD, a booklet of Undertale sheet music, and a collector's box with slipcase.
