Steam has opened a limited-time free promotion for Diablo 4, giving PC players access to Blizzard’s open-world action RPG until September 21. The platform has also confirmed Fireside Feelings for an October 2026 free-to-keep promotion, while Crystal Crisis is already available to claim permanently through September 22.
What happened on Steam
Diablo 4 is available to play at no cost on Steam until September 21 at 10 a.m. PT / 1 p.m. ET. The offer arrives as part of Steam’s Free Weekend-style promotions and coincides with Diablo 4’s 30th anniversary celebration. It is not yet clear whether the anniversary promotion will be Steam’s only major free-play offer through that date or whether another title will be added during the platform’s usual Thursday update cycle.
This is a temporary access promotion rather than a permanent giveaway. Players can explore Diablo 4 during the event, but access ends when the promotion expires. Steam is also listing the game at 75% off, reducing its price from $49.99 to $12.49 for anyone who wants to continue playing afterward.
Why the offer matters for players
Diablo 4 remains one of the most visible action RPGs on the market, combining a dark fantasy setting with open-world exploration, class-based character building, dungeons, bosses, and a long-term loot chase. Players can use the free period to test the game’s systems and sample its newer content without committing to a purchase.
The timing is also notable because Diablo 4 Season 15 experienced a short delay before launch. The source indicates that the major problems have been addressed, allowing players to jump into the latest seasonal content during the free period. Blizzard has also confirmed Diablo 5, giving the current game additional significance as the franchise’s active foundation.
What to watch next
Steam’s next confirmed free-to-keep promotion is Fireside Feelings in October 2026. Unlike a free-play weekend, this type of offer lets users keep the full game permanently if they claim it before the promotion ends. Fireside Feelings is a single-player, dialogue-focused cozy experience from Team Empreintes. It centers on conversations held around a campfire, with subjects including memories, fears, personal experiences, and everyday life. Its relaxed, hand-drawn presentation offers a sharp contrast to Diablo 4’s combat-heavy fantasy world.
For an immediate permanent addition, Crystal Crisis is free to keep until September 22. The competitive puzzle game combines falling-block mechanics with fighting-game systems: players match crystals, build a Burst gauge through combos, and spend it on offensive or defensive moves. Steam currently shows Fireside Feelings at 96% Very Positive from 267 reviews, while Diablo 4 has a 73% Mostly Positive rating from more than 21,000 reviews.

Expert View
Steam’s promotion is strongest when treated as a funnel rather than a single giveaway. Diablo 4 offers a high-profile trial that can convert curious players through its steep discount, while Crystal Crisis supplies an immediate permanent claim and Fireside Feelings gives users a smaller, more distinctive game to anticipate. For Blizzard, the free period is a timely way to bring new players into Diablo 4’s seasonal ecosystem without removing the value of the full purchase.
