Steam Next Fest starts Monday: two demos show the range ahead
Ball-Aqua tests momentum and Submundus turns injuries into cards. The October festival begins at 19:00 in Italy, with a clock-change wrinkle at the end.
Steam Next Fest's October edition starts on Monday, October 19, at 19:00 in Italy, opening a week of demos for upcoming PC games. Two available demos already illustrate the range: Ball-Aqua turns momentum into a cooperative obstacle course, while Submundus makes hunger and injuries part of a deck of cards.
Valve's official schedule runs from October 19 at 10:00 PDT to October 26 at the same Pacific time. There is a small calendar trap for European players: clocks change during the event, so it ends at 18:00 CET in Italy, an hour earlier on the local clock than it begins.
The festival is still ahead
The press preview began on October 8, and individual developers can make demos available before the public festival. Neither means the main event has already started. That distinction explains why a playable demo and a “coming to Next Fest” announcement can appear together this weekend.
Next Fest is organized around upcoming releases. The demo is a sample of a game still being developed, not proof that the finished product is available. Valve allows a title to participate in one Next Fest, so the timing also represents a developer's choice about when to put a playable build in front of a larger audience.
There is no single official livestream to wait for. Valve moved developer broadcasts into a separate tab in an earlier revision of the event. Watching a stream and downloading a demo are therefore independent ways to explore a game.
Ball-Aqua: learning the weight of a rolling world
Dreaming Saints' Ball-Aqua store page offers a free demo now and lists the full game's planned release for February 25, 2027. Its central action is rolling a ball through tropical courses, preserving speed, jumping gaps and negotiating obstacles. Online co-op sits alongside solo exploration.
The full-game description includes Race, in which players add a building piece before a round, and King of the Hill. It also describes a level editor and Steam Workshop sharing. These are the project's advertised features; the store page should not be read as a guarantee that every listed mode is present in the current demo.
Momentum-based platforming is particularly suited to a playable sample. A trailer can show the route, but the appeal depends on how steering, acceleration and recovery feel under the player's hands. A few attempts can answer whether correcting a near miss is satisfying or frustrating far more directly than another minute of footage.
The page lists an Italian interface and controller support. Those details help narrow the practical audience without treating the demo as a finished-game review.
Submundus: damage that changes your next hand
Tabula Forge's Submundus page also provides a demo. Its dungeon-crawling design represents wounds, hunger and exhaustion as cards added to the player's deck. Survival problems therefore affect the composition of future hands rather than only reducing a separate health bar.
Time advances through deck cycles, linking the size and contents of the deck to the pace of survival pressures. A harmful card can occupy space that might otherwise offer a useful action. That creates a different kind of resource problem from simply finding the strongest attack: keeping the deck functional becomes part of keeping the character alive.
The main game is listed as coming soon to Early Access, without a firm release date. Its current language list includes English, Spanish and Portuguese, but not Italian. The developer expects an unfinished release to grow through feedback; that intention is separate from a promise that all planned content will arrive on a fixed schedule.
These two demos are starting points, not a ranked list of winners. One asks the player to manage physical motion; the other turns bodily setbacks into tactical clutter. Their contrast is a useful reason to try a sample outside a familiar genre. For the wider PC gaming audience, the festival's practical value is the opportunity to replace a wishlist assumption with an actual experience of the controls and systems before buying.
