New on Steam, including a new game from IO Interactive veterans

Welcome to the series that discusses the most important upcoming releases on Steam. This week is gonna be noticeably slower than the last ones, but we can still expect a few cool new releases.

Release of the week: Raiders of Blackveil (Early Access on December 15, 2025)

For the release of the week, we chose Raiders of Blackveil. The title will combine elements of action RPG, roguelite, and extraction game, allowing for solo play or cooperative mode. Each player picks a character from a lineup of humanoid animals, each with their own special abilities, kind of like the heroes you'd find in a MOBA game.

This is the first project of Wombo Games studio, a new team founded by one of the co-founders of IO Interactive. The demo released a few months ago made a very good impression, so we have high expectations for this game.
