Boosteroid has added selected Next Fest June 2026 game demos to its cloud gaming service, letting you sample part of the demo event through the cloud. The main planned demo list includes 24 game names, with Mortal Shell II, Mistfall Hunter, and Onimusha: Way of the Sword listed separately through Boosteroid’s Install section.
Next Fest ends on June 22, 2026, but Boosteroid plans to keep selected demo clients open through the end of July when developers keep those demos available. That leaves this June batch with a longer access window than the event itself. Availability can still change from demo to demo.
Boosteroid Adds Selected Next Fest June 2026 Demos
The June list is mostly about quick sampling. Next Fest puts a lot of upcoming PC demos in front of you at once, and Boosteroid is making a smaller group available through cloud access.
Demo access depends on the event window, developer availability, and whether each demo client keeps working through the cloud after the festival week.
To access the demos, open the Next Fest session in Boosteroid, go to your Steam library, filter for “Demo,” and choose one of the listed games.

Three More Next Fest Games Appear In The Install Section
Boosteroid also points to three Next Fest games in its Install section. Those are Mortal Shell II, Mistfall Hunter, and Onimusha: Way of the Sword.
Those three games are connected to Boosteroid’s Next Fest coverage, but they aren’t part of the 24-game demo list above. If you’re checking Boosteroid during Next Fest, look for Mortal Shell II, Mistfall Hunter, and Onimusha: Way of the Sword in the Install section instead.
Boosteroid Plans Demo Access Beyond Next Fest
Next Fest ends on June 22, 2026, but Boosteroid plans to keep selected demo clients open through the end of July. Continued access depends on developers keeping those demos available.
Some demos can change during or after Next Fest. Others can become temporarily unavailable or need extra work before they play properly through the cloud. Updates made to a demo can also affect whether it remains playable through Boosteroid.
If one of these demos is on your play list, don’t wait until late July to try it. Boosteroid plans to keep selected access open after Next Fest, but the demo clients still depend on developer availability.
