There is no confirmation yet, but console versions of Hades 2 will likely release shortly after the Early Access period on PC is over. This was the case for the previous game where Hades 1 stayed on Early Access for 2 years, and released on consoles after about 10 months.
Hades 2 is expected to have a shorter Early Access period compared to the first game, so it’s expected that the wait for console versions would be shorter as well.
Switch, PlayStation, and Xbox
It’s possible that the Switch version of Hades II will launch alongside the full 1.0 release on PC, just as it did with the first game. The PS4, PS5, Xbox One, and Xbox Series X/S received their ports shortly after. The iOS also received a port of the original game much later.
The Early Access period of Hades II is much shorter, so a simultaneous release on all consoles could also be a possibility. This is taking into consideration the amount of content already available, and the developers already having experience porting to other consoles.
