Steam Winter Sale 2025: 10 Unmissable Game Deals to Grab Before They’re Gone

The Steam Winter Sale 2025 just went live, and yes, it is the annual wallet hazard. You should absolutely grab the stuff on your wishlist, but a few deals are so wild they deserve a siren and a shove to the front of the line. Here are the ones I would not sleep on.

1. Detroit: Become Human — 90% off — $3.99
   Quantic Dream's big branching narrative hit is at an all-time low for the first time, and it is built for anyone who likes their choices to actually matter. You play from the perspective of three different characters, and the ripple effects are everywhere: what you say, what you pick up, which route you take. The game boasts over 40 endings with 85 variations, which is a polite way of saying you will stress over every decision. Grab it on Steam.

2. The Witcher 3: Wild Hunt Complete Edition — 80% off — $9.99
   If you somehow missed Geralt's monster-hunting opus, the Complete Edition gets you the base game plus all expansions for ten bucks. There is chatter about new Witcher 3 DLC in 2026, so this is not a bad moment to jump in or replay. Massive open world, loads of meaningful quests, and enough choice-driven outcomes to keep you busy until spring. On Steam.

3. The Walking Dead: The Telltale Definitive Series — 90% off — $4.99
   The full Telltale collection, including 400 Days and Michonne, with visual upgrades baked in. If you want a top-tier story that smacks you around emotionally, this is it. Plan for roughly 50 hours, depending on how often you pause to decide who to save. On Steam.

4. Hogwarts Legacy — 90% off — $5.99
   It recently went free on the Epic Games Store, but if you missed that window, the Steam sale price is the next best thing. Even if you're not deep into wizard lore, the open-world RPG setup lets you chart your own path and stir up trouble (or not) around Hogwarts. On Steam.

5. ACE COMBAT 7: Skies Unknown — 90% off — $4.79
   Dogfights with a photoreal edge, full 360-degree movement, and that "I am actually in the cockpit" feeling. It is also at an all-time low, and there is a sequel lined up for 2026, so consider this a perfect warm-up. Just know the learning curve will happily fling you into the ocean if you get cocky. On Steam.

6. Planet Zoo — 90% off — $4.49
   Build the zoo you wish your city had. You design habitats, manage the ecosystem, and populate your park with animals from all over the world. The simulation is deep, and you can even research new generations to fold into your carefully curated animal family. On Steam.

7. Assassin's Creed Valhalla — 90% off — $5.99
   This one hit Steam in December 2022, and three years later it is down to six bucks for the sale. You play as Eivor, a Viking carving out a life in the Dark Ages. Yes, it is Assassin's Creed at heart, but the settlement-building and reputation systems add a nice twist to the usual stealth-and-stab routine. On Steam.

8. Fallout 76 — 90% off — $3.99
   The Fallout wasteland, but with neighbors. Set 25 years after the bombs drop, it is a multiplayer spin where you craft your story, make choices that stick, and, if diplomacy fails, there is always the nuclear option. Literally. On Steam.

9. LEGO Star Wars: The Skywalker Saga — 90% off — $4.99
   All nine films retold with LEGO's signature goofball charm. You can tackle the saga in any order, hop between a ridiculous roster of characters, and pilot an equally ridiculous array of ships. It is comfort food with lightsabers. On Steam.

10. Dead Island 2 — 90% off — $4.99
    After a long road to release, it finally arrived in April 2024. Now it is five bucks to own on Steam. Sun-soaked Los Angeles, a zombie survival sandbox, and a build-your-beast loadout system that lets you tailor weapons and upgrades to your playstyle. Co-op is in, so bring a friend and make a mess. On Steam.

That is a lot of game for not a lot of cash. What are you picking up?
