Steam Next Fest June 2026: 25 Of The Best Demos You Can Play Right Now

We're spoiled for choice these days when it comes to video games, with hundreds of new titles released each month. What should you play? What's worth a roll of the dice that hopefully won't end with buyer's remorse? Those are questions that Steam Next Fest answers several times a year, and the June Edition of this festival of demos has kicked off. Admittedly, it's impossible to cover every game demo taking part this week, as the June edition of Next Fest has over 4,000 to sample. We’re also not listing any demos that we previously covered in the February 2026 edition of Next Fest, but if you’re curious, you can read up on what you missed through this link. But if you're worried about choice paralysis, fret not, because we've gathered some of our top picks below. Next Fest caters to every taste, from wholesome games to survival-horror, and once it wraps up on June 22, you can look forward to a few more Steam events throughout 2026. If you're also saving your cash for some new games, the Steam Summer Sale will kick off on June 25 and run through July 9. Onimusha: Way of the Sword Capcom's next big game of 2026, Onimusha: Way of the Sword got a demo during Summer Games Week. It's still worth checking out for its hack-and-slash action, plus it's not limited to PC. See on Steam Valor Mortis While you're going to have to wait a little longer to play the full version of this first-person souls-like from the studio behind the Ghostrunner games, you can get an idea of what Valor Mortis is about with this demo. As a former soldier of Napoleon's army, you're flung into a European battlefield full of monsters, creatures that'll test your reflexes, weapon skills, and newly acquired magical powers. See on Steam Toem 2 The original Toem is one of our favorite games thanks to its combination of spotting hidden objects, clever use of photography mechanics, and a beautifully designed monochrome world. The sequel looks like it'll be expanding on those ideas ahead of its release in Q3 2026, and this demo will give you a taste of documenting the world's little wonders. See on Steam Lost in Art Now that we think about it, an art gallery is the perfect venue for a horror game. While Lost in Art doesn't go full survival-horror, the game does use its location to craft puzzles that require creative thinking, hide sinister threats in the shadows, and wrap the entire experience in an eye-catching art direction. See on Steam Outrange Strike While the next Ace Combat is a few months away, you can still take to the skies--and for free--in this demo for Outrange Strike. An ambitious blend of arcade action and flight-simulator elements, it's all about building specialized aircraft and then using them to keep the skies safe. See on Steam Penguin Colony I absolutely abhor penguins for the vile, disgusting creatures that they are, which is probably why I'm hoping things end terribly for the malevolent mammal you play as in this faithful re-imagining of H.P. Lovecraft's At the Mountains of Madness. Developed by Umurangi Generation studio Origame Digital, the game follows the events of the cosmic-horror story, but through the eyes of a penguin. See on Steam The Sinking City 2 Speaking of Lovecraftian vibes, don't forget to check out The Sinking City 2 demo either! Frogwares is dialing up the survival-horror aspects of the sequel, and this demo will show you how the studio is focusing on deliberate dread, devious puzzles, and resource-lean gameplay. See on Steam Hack 95 We all know how modern operating systems kind of suck nowadays, which is why a game like Hack 95 might catch your eye. Inspired by a golden era of operating systems, Hack 95 is a card-based computer-hacking experience where you're tasked with taking down evil organizations. Also, an incontinent virtual pug is there to help you. See on Steam The Old Flesh of Nuraga Dipping back into the pool of thrills and chills, The Old Flesh of Nuraga is a first-person psychological-horror game with an eye-catching art direction. Set in the sands of a creepy desert, players will search the area for strange treasures and keep an eye on their digital grandfather as he descends into madness--which sadly, isn't the '80s British ska band. See on Steam Pulsebreaker We really are living in a golden age for horror games, aren't we? Pulsebreaker describes itself as a classic PS1-inspired survival-horror--and it certainly looks the part--but with a few modern ideas thrown into the mix. It's a blend of old-school exploration, puzzle-solving, and resource management, while the Focus Meter gameplay mechanic is designed to reward precision and composure when you're pressured by hordes of monsters. See on Steam Maximum Thunderness For something more wholesome, you can grab a demo for Maximum Thunderness next. A roguelike sidescrolling co-op action game, you'll get to respond with extreme force to the minor crimes of the sinister SKULL organization in this retro-inspired romp.
