From Valve:
We host Steam Next Fest three times a year to help developers connect their not-yet-launched games with an audience, and the first one of 2026 is upon us:
The February edition of Steam Next Fest starts February 23rd at 10 a.m. Pacific, kicking off a full week of free demos of games from all genres.
Play as many demos as you want, and wishlist the ones you like so you can stay notified the moment they officially launch! You'll also find developer chats and livestreams throughout the week.
Steam Next Fest: February 2026 is February 23rd through March 2nd at 10 a.m. Pacific. See you there!
