Developer announcements on Steam describe festival demos and promotions through early November. Check each game’s requirements, offer deadline and refund conditions before buying.
Steam’s Halloween period is bringing a new group of horror game promotions and demos to players. Developer announcements on the platform describe participation in Steam Scream V, with several listing October 26 through November 2 as the festival window. Individual games can use different offer times, so the date shown on each product page is the relevant check before purchase.
An October 27 Dionous Games press release lists Inner Voice, Cult Vacui, Sleepytime Village and Deep Siren among its participating titles. It schedules Sleepytime Village for October 30 and says Deep Siren has a free demo while its full release remains undated. These are publisher statements, not independent reviews, and festival participation does not establish that every game is discounted or already complete.
Valve’s refund page says games generally qualify for a requested refund within fourteen days of purchase and with less than two hours played, subject to the detailed conditions and exceptions it lists. Checking hardware requirements, supported operating systems and demo availability can therefore be more useful than judging a purchase by the percentage discount alone. The Steam Deck photograph is background platform imagery, not a claim of compatibility for every featured game.
