50 Most-Played Steam Next Fest Demos Are Heavy On Horror And Adventure

We’ve had our eye on Marvel Cosmic Invasion for a while, so it wasn’t too shocking to see that on the list. However, Star Trek: Voyager – Across the Unknown, was unexpected and it offers an intriguing glimpse at a chance to rewrite some of the stories that took place on that series.

Most of the games that made the list either have active demos that can still be downloaded, or they’re already in early access. The next installment of Steam Next Fest is scheduled for February 2026, but the complete list of the 50 most-played demos from this month’s event is reproduced below.
