Steam’s Free-to-Keep promotion is giving away IQ Under Construction, Moonrise Fall, and Drift86 at no cost. Claim all three before their deadlines and they’re yours permanently.
Steam’s Free-to-Keep promotion is currently offering three games at no cost: IQ Under Construction (normally $2.99), Moonrise Fall (normally $9.99), and Drift86 (normally $1.99). Together, that is $14.97 worth of games you can claim for free and keep permanently. Each title has a different expiration window, so acting quickly matters. Once added to your account before the deadline, they stay in your library forever.
Which Games Are Free and When Do They Expire?
All three titles are part of Steam’s rolling Free-to-Keep promotion, but their claim windows end at different times:
- IQ Under Construction: Free until June 1, 2026 at 10:00 AM PT / 5:00 PM UTC.
- Moonrise Fall: Free until June 2, 2026 at 10:00 AM PT / 5:00 PM UTC.
- Drift86: Free until June 3, 2026 at 9:00 AM PT / 4:00 PM UTC.
IQ Under Construction has the tightest window. If you are reading this on June 1, claim it immediately. Moonrise Fall and Drift86 give you a bit more breathing room, but there is no reason not to grab all three right now in a single session.
What Is IQ Under Construction?
Developed by PoseidonPlay and released on June 19, 2025, IQ Under Construction is a chaotic multiplayer platformer built around teamwork and precision jumping. Players are connected by an invisible energy tether: stray too far from your teammates and everyone gets sent back to the beginning. It supports up to 4 players in online co-op, and solo play is also available. Think of it as a mix of Chained Together and Only Up!, according to OpenCritic’s comparison. Built on the Unity engine, the game has modest system requirements: Windows 10, a 3.2 GHz dual-core CPU, 4 GB RAM, and Intel HD Graphics.
The game currently sits at roughly 45% positive across 317 Steam reviews on SteamDB. Mixed reception aside, the price tag of zero makes it well worth trying, especially if you have a group of friends who enjoy cooperative platforming chaos.
What Is Moonrise Fall?
Moonrise Fall is an atmospheric exploration puzzle game developed by Made From Strings and published by GrabTheGames. Originally released on May 31, 2019, it tells the story of a boy who becomes lost in a supernatural forest after losing both parents in a car crash. Armed with a clue-filled journal, a camera, and a lantern, players unravel the forest’s mysteries and photograph the cryptids dwelling within it.
Critics received it warmly: Adventure Gamers gave it 4.5 out of 5, The Indie Game Website awarded 8/10, and Gamewatcher also scored it 8/10. On Steam, 88% of 25 user reviews are positive. The game features a dynamic day-night cycle, a playable in-game Kalimba instrument, procedural music layers, and varied puzzle types across caves, mines, and otherworldly locations. System requirements are extremely low: Windows Vista, 4 GB RAM, a DX9-compatible GPU, and just 600 MB of storage.
What Is Drift86?
Drift86, developed by RewindApp and fully released in November 2019, is a drift-focused arcade racing game. It offers over 40 different cars, more than 30 maps, an addictive drift combo system, and Eurobeat-fueled soundtracks. Both single-player and online multiplayer modes are available, along with Steam Achievements, Trading Cards, and Leaderboard support. Xbox controller compatibility is included.
With 5,286 total reviews and a “Very Positive” overall rating (90% positive), Drift86 is comfortably the best-reviewed of the three free titles. Recent reviews from the last 30 days sit at “Mostly Positive” with 78% approval from 28 reviews. Minimum requirements are light: Windows 7 or later (64-bit), a 2 GHz processor, 4 GB RAM, Intel HD Graphics, and 2 GB of storage.

How Steam’s Free-to-Keep Promotions Work
Unlike the Epic Games Store’s weekly giveaway schedule, Steam’s Free-to-Keep promotions do not follow a fixed calendar. Developers and publishers opt into the promotion at their own discretion, and Steam features these deals on SteamDB’s upcoming free games tracker as well as directly on store pages. Once you claim a Free-to-Keep title before its expiration, the game stays in your account permanently, even after it returns to its normal price.
This is different from Steam’s “Free Weekend” events, where you can play a game temporarily but lose access once the weekend ends unless you purchase it. Free-to-Keep means the game is yours for good, no strings attached. According to SteamDB, at least five more Free-to-Keep titles are expected on Steam during June 2026.
Which One Should You Claim First?
Prioritize IQ Under Construction since its deadline is the earliest (June 1). Then grab Moonrise Fall (June 2) and Drift86 (June 3). The entire process for all three should take under five minutes. Even if you are unsure whether you will play them, there is no cost to adding them now and deciding later.
Things Worth Knowing Before You Claim
Do I need to install the games right away? No. Adding them to your account is enough. You can install them whenever you want afterward.
Can I play these on Steam Deck? Yes. IQ Under Construction and Drift86 both show Steam Deck play data on their store pages. Moonrise Fall’s low system requirements also make it a strong candidate for handheld play.
Are there any hidden costs or subscriptions? None. A free Steam account is all you need. No payment information is required to claim Free-to-Keep titles.
Where can I track future free game deals? SteamDB’s free promotions page, GamerPower, and community groups like Free Games Finders on Steam are reliable sources for spotting upcoming giveaways.
If you are looking to expand your Steam library beyond free promotions, GamerMarkt’s Steam Accounts marketplace offers a range of pre-loaded accounts with large game collections. Whether you want to buy an account with specific titles or sell one you no longer use, the platform provides a secure environment for Steam account transactions.
