According to the announcement, the game will be available via the Nintendo Switch eShop for the Americas, Europe, Australia, and Japan on that date, so you’ll want to mark down that date on your calendars if this is a game that you’ve been anticipating, a game which we should mention won the Best Indie Game at the Golden Joystick Awards in 2016.
The description of the game on its website reads, “The year is 1989 and you’ve just taken a job deep in the Wyoming wilderness. Alone for the summer with nothing to do but spot fires, your supervisor Delilah is always just a call away on your radio—and as you’re pulled out of the tower into the dense forest below, she’s your only contact with the world you’ve left behind.”

Also earlier this year, it was announced by the developer that they had been acquired by Valve, which from what we can tell technically makes it the first game under Valve’s banner to be released on the Nintendo Switch.
