Supergiant Games announces Hades, a new hack-and-slash game from this studio that created Bastion and Transistor. The Hades Website is live, revealing that this is available right now in Early Access. They have an Early Access FAQ to explain the process, and an Early Access Trailer to show off the game. This is offered through the new Epic Games Store, so there's another adventure to be had along the way for those who want to visit the underworld. Supergiant Games offers this brief description:

Hades is a rogue-like dungeon crawler in which you defy the god of death as you hack and slash your way out of the Underworld of Greek myth. Now available in Early Access.
