Icarus, Killing Floor 3, and Metal Gear Solid are among the titles you can play without spending a cent — and deep discounts make it easy to keep them.

Steam's latest Free Weekend promotion is live, and it's a generous one: six games are available to play for free until July 27 at 12 pm CT. Among them are a mix of survival, co-op, and action titles, including,, and. If you've been on the fence about any of these, now's your chance to try them without spending a dime — and if you like what you play, deep discounts are running alongside the promotion.

The Six Games You Can Play for Free

Here's the full lineup for this Steam Free Weekend (July 23–27):

  • Icarus — A session-based survival game from the creator of DayZ. Drop onto a hostile alien world, gather resources, complete contracts, and extract before time runs out. Supports up to 8 players.
  • Firefighting Simulator: Ignite — A realistic firefighting simulation with co-op play. Also available on PS Plus Extra this month.
  • Killing Floor 3 — The next installment in the beloved co-op zombie shooter series. Expect waves of grotesque enemies and over-the-top weaponry.
  • Wild Assault — A competitive team-based shooter with unique animal-themed characters.
  • Unrailed 2: Back on Track — A chaotic co-op railway-building game where you and friends must keep a train moving by laying tracks in real time.
  • Metal Gear Solid - Master Collection Version — The classic stealth-action collection, now available for free on Steam for the weekend. Also part of Xbox's Free Play Days.

Each game can be played for the full duration of the weekend. Given that some titles like Icarus and Killing Floor 3 can be completed in a single session or at least make significant progress, you might even "beat" them without paying a cent.

Why This Weekend Matters

Steam Free Weekends have become a reliable way for publishers to boost visibility and sales, especially during the slower summer months. This particular promotion arrives just as many players are looking for something to fill the gap between major releases. The lineup is notably heavy on survival and co-op games — a trend that's been growing since the pandemic, as players seek shared experiences.

What's interesting is the inclusion of Metal Gear Solid, a single-player narrative classic. It's a rare opportunity for those who missed the series the first time to experience Hideo Kojima's stealth masterpiece without commitment. For comparison, if you prefer story-driven games like Alan Wake, Metal Gear Solid offers a similarly cinematic, twist-filled adventure.

The Discounts Running Alongside the Free Play

If you decide to keep any of these games, the discounts are substantial. Here's the current pricing:

  • Icarus — 80% off until July 30, dropping from $34.99 to $6.99.
  • Firefighting Simulator: Ignite — 50% off, available for $14.99.
  • Killing Floor 3 — 20% off, bringing it to $39.99.
  • Wild Assault — 30% off, priced at $13.99.
  • Unrailed 2: Back on Track — 25% off, now $14.99.
  • Metal Gear Solid - Master Collection Version — 40% off, $19.99.

These deals are valid through the weekend and in some cases a few days after, so you have time to decide.

How the Free Weekend Changes the Calculus

For players, the biggest benefit is zero-risk testing. Icarus, for example, has a learning curve that can be off-putting at full price. A free weekend lets you figure out if the extraction survival loop clicks — and at $6.99, it's a steal if it does. Similarly, Killing Floor 3 is a game that lives or dies on its co-op feel; playing with friends for free tells you everything you need to know about the AI enemy behavior and weapon balance.

For indie developers, the exposure is invaluable. Unrailed 2 and Wild Assault might not have the marketing budgets of bigger titles, but a slot in a Steam Free Weekend can drive hundreds of thousands of downloads and convert a significant percentage into sales. The AI arms race of discovery algorithms means that a spike in concurrent players can boost a game's visibility for months.

Comparisons to Other Free Weekend Offerings

Steam's Free Weekend promotions have become more frequent and more curated. This one stands out for its variety: it's not just shooters or survival games. The inclusion of Firefighting Simulator: Ignite and Unrailed 2 shows that Steam is pushing for niche genres that might not otherwise get a tryout. For those who prefer shorter, cozier experiences, A Short Hike remains a gold standard, but Unrailed 2 offers a similar low-stakes, high-fun vibe with friends.

Meanwhile, Icarus shares DNA with extraction shooters like ARC Raiders, though it leans more heavily into crafting and survival. If you're a fan of that genre, you'll find familiar tension in the "drop in, survive, extract" loop.

A Note of Caution

Not every game in this lineup is a winner. Icarus has a "Mostly Positive" rating on Steam, but some players find the session-based structure frustrating — losing progress after each drop can feel punishing. Killing Floor 3 is still in early access, so balance and content are in flux. And Metal Gear Solid, while beloved, shows its age in controls and camera design. The free weekend is the perfect way to judge these downsides for yourself.

There's also the question of why these specific games were chosen. Industry observers note that free weekends often precede significant content updates or sequels. Killing Floor 3 is still building its player base, while Icarus recently released a major expansion. The timing suggests these publishers are looking to convert new players ahead of upcoming DLC or seasonal events.

What to Play First

If you only have a few hours, prioritize based on your taste:

  • For co-op chaos: Killing Floor 3 or Unrailed 2.
  • For deep survival: Icarus.
  • For narrative stealth: Metal Gear Solid.
  • For something unique: Firefighting Simulator: Ignite.

All six games are available to download and play now through July 27. After that, the free weekend ends, but the discounts linger for a few more days. Don't sleep on this — it's a rare chance to build a library without spending a dime.
