The next game from Supergiant Games, the creators of Transistor, Pyre, and Bastion, was revealed at The Game Awards 2018. Hades is coming, and it is already available on The Epic Games Store as an Early Access title. It is $19.99. (Though, when you first visit the site, it might initially say it is free.)
Here is the Hades Early Access trailer.
Hades is a rogue-like dungeon crawler. People will attempt to get out of the underworld and will apparently start back at the beginning after they die. As it goes through Early Access, it will get new characters, events, features, and powers.
Hades is immediately available on PCs.
