Innersloth is celebrating eight years of Among Us by doing something it has never done before: making a single-player game. Among Us Story: On Guard is a narrative whodunnit set in the Among Us universe, and its free demo went live on June 15, 2026 as one of the marquee entries in this month's record-breaking Steam Next Fest — landing on the exact anniversary of the original game's launch on June 15, 2018.
Rather than another round of frantic multiplayer social deduction, On Guard casts you as Guard, the Crewmate responsible for shipwide security. Everything aboard is running smoothly — right up until there is a murder. From there it becomes a solo investigation: you sift through clues, interrogate the rest of the crew, and try to unmask the Impostor while clearing your own name.
A familiar world from a brand-new angle
The demo leans into the cartoonish charm that turned Among Us into a phenomenon, but reframes it as a story-driven mystery with multiple endings that hinge on how your investigation plays out. Crucially, it is a standalone game on Steam rather than a mode bolted onto the existing app, signalling that Innersloth wants to grow Among Us into a setting that can carry whole new genres.
Innersloth confirmed during Summer Game Fest 2026 that On Guard is a full spin-off, with the Next Fest demo serving as an early taste ahead of release. A final launch date has not been announced — the Steam page currently reads “Coming Soon” — but the studio is clearly using the festival window and the eighth-anniversary celebration to put the project in front of as many players as possible.
Why it matters
Eight years on, Among Us remains one of the most recognisable games on the planet, and On Guard is the clearest sign yet that Innersloth is treating it as a universe, not just a single title. Pivoting from chaotic group betrayal to a quiet, single-player murder mystery is a bold tonal swing — the kind of experiment a studio can only attempt once it has the audience to back it.
The demo is available now through Steam Next Fest, which runs until June 22. If the reception is strong, expect Innersloth to firm up that release window sooner rather than later.
