Chapter 1 for free, others not so free
It turns out the excellent Undertale spin-off/sequel, Deltarune, will be heading to Nintendo Switch soon. The first chapter will be hitting the eShop on February 28, 2019, for free. The teaser trailer confirmed that the rest of the game will be coming, as well: it just won’t be free.
I don’t know a whole lot about Deltarune, but the teaser is sufficiently spoiler-free. If you want to take a gander, feel free to watch the clip and then patiently wait for the game to arrive.
