As Phoenix Labs announced, Dauntless will arrive to Xbox One, PS4, and Nintendo Switch in 2019.
The beta launched earlier this year on PC and it will arrive to Xbox One and PS4 in April 2019. The Switch version will come a bit later. We don't know exactly when yet, but it shouldn't be too long before we see it on Ninty's console too.
Dauntless is heavily inspired by Monster Hunter. You take control of a slayer (yes that's the name of the characters) and you need to hunt down various abominations called Behemoths. The name is chilling, but they're not that tough really.
