The Ascent is the latest Game Pass release to succeed beyond Xbox's service

The Ascent generated $5 million in revenue and topped the Steam global sales chart over its opening weekend. That's according to publisher Curve Digital, which is hyping up the indie hit as a true "triple-A competitor." That success is even more impressive considering many players could get the game at no additional cost through Microsoft's Xbox Game Pass service on console, PC, and the cloud.
