Epic Finally Discovered Linux (Valve Made It Pay), and Bungie Still Won't Flip the Switch for Marathon

Epic spent a decade treating Linux like a rounding error. This week it shipped a Linux launcher and EAC Linux v2, riding the ecosystem Valve built. Meanwhile Bungie, sitting on a dwindling Marathon, still won't let Linux players in.

Epic Finally Discovered Linux (Valve Made It Pay), and Bungie Still Won't Flip the Switch for Marathon

October 14, 2026. The wire starts rattling, and Epic Games, the same company that spent ten years telling the Linux faithful to go die quietly in a forum, has just discovered the Lord. Not the real Lord. The other one. The one with a shopping cart. It shipped a Linux launcher and a rebuilt anti-cheat called EAC Linux v2, and now it wants a parade. Fine. But the real crime this week is happening down the hall, where Bungie is watching its newest game drown while it sits on the one switch that could save it, and refuses to flip it.

Let me set the scene, because you need to understand the sickness before I show you the patient.

For years, Epic Games treated Linux the way a landlord treats a leaking basement: aware of it, in the way you are aware of a smell, and emotionally committed to never doing one single thing about it. The Epic Games Store had no shopping cart. Say that out loud to somebody who was not there and watch their face. The launcher was a slow, janky storefront stapled to a game runtime, and every time Linux came up, the official answer was some soft corporate noise that translated, in every language, to "we will look into it" and then never look.

Then Valve took the platform seriously, and the arithmetic changed overnight. The Steam Deck shipped. Proton grew teeth. The next wave of Steam hardware, the Steam Machine and the Steam Frame and the new controller, sold out and slid into backlog. Suddenly, for the first time, ignoring Linux carries a price tag a shareholder can read. Epic noticed. Epic always notices, especially money. There is no other kind of noticing at this scale, and pretending otherwise would be the most generous sentence ever printed on a website this small.

What Epic Actually Announced

Two posts, same day, and the first one is a gift from God.

It is a new Epic Games Launcher Preview build, and here is the opening line, verbatim, from the company's own news post: "Programming is hard. So, instead of doing that, we vibe coded a new Epic Games Launcher that's way faster and more responsive than the current one." Then it admits the thing is "light on features," calls it "a speedboat and not a yacht," and jokes, I am not making this up, that it does include "advanced digital commerce technology such as a shopping cart." That is Epic, in the year of our Lord 2026, selling you a shopping cart as a revelation. The build runs on Windows, macOS, and, in their words, "for the first time, Linux."

The second post is where the blood is. Epic is rebuilding its Linux anti-cheat into EAC Linux v2. Their framing, for once, is almost honest. EAC has technically supported native Linux since 2014, and Wine and Proton since 2021, but the whole thing is opt-in per game, and most studios never opted in because the Linux version offered weaker protection than the Windows one. That weakness, by Epic's own admission, is the reason Fortnite has never run on Linux. Now, they say, they are closing the gap.

Epic Is Riding the Rails Valve Laid

Let us be cold about the credit, because Epic will not be.

Epic is not pioneering anything here. Proton is Valve's. SteamOS is Valve's. The only reason a Linux anti-cheat announcement is commercially interesting in 2026 is that Valve spent a decade dragging Linux out of the basement and into a storefront with a hardware roadmap. Epic is arriving late to a party it did not throw, in a jacket it borrowed from the host.

Strip the varnish off the new stack and you get a list of Linux features that already existed: signed kernels and signed kernel modules, TPM 2.0, Secure Boot, measured boot, IOMMU, kernel lockdown in integrity mode, kexec disabled, and BPF LSM hooks. No kernel driver. No always-on watcher. Just eBPF and a systemd service that wakes when a protected game opens and dies when it closes. And Epic, to its credit or its marketing department's, nods straight at Valve, promising to keep its "open line of communications with Valve to support Steam Hardware devices to the maximum extent technically possible."

So here is the awkward little truth at the center of the celebration. Epic spent years dismissing the platform, and is now showing up to a market Valve built, carrying a rebuilt anti-cheat that only stands up because other people poured the foundation. Late support is still support. A rising tide lifts all launchers. But do not let anyone in a nice suit call it foresight.

And this is where the party gets ugly. The single most popular Linux gaming device on the planet cannot use it. Epic's own FAQ, verbatim: "The Steam Deck does not support the required features for our EAC v2 solution, but we are actively talking with Valve and hope to support it in the future."

Read that again, slowly. Epic announces Linux support and, in the same breath, confesses that the Steam Deck, the machine that made this conversation possible, the handheld that put Linux gaming in millions of backpacks, is shut out on day one. The "well-known" signing keys read like the guest list for the desktop Linux elite: Canonical, Fedora, Universal Blue, Debian, openSUSE, SUSE, Rocky, AlmaLinux, and Microsoft's own UEFI CA. Bazzite, the distro that feels most like a console, sneaks in through Universal Blue. The Deck does not. Epic is romancing the Linux desktop while stepping over the handheld that millions of people actually game on.

Which Brings Us to Bungie

Now. Pour something strong and sit down, because I have to tell you about Bungie.

Bungie, the great and fallen house of Destiny. Bungie, who has never once, in any year, in any capacity, opened the door to Linux. Not a crack. Not a sliver of light. The online service never supported it, and neither did anything else they have ever built.

And here is the obscenity, the little detail that made me put my head in my hands and laugh like a man watching his own house burn: they already own the key. Destiny 2 runs on BattlEye, and BattlEye has offered Proton and Linux support for years. The switch exists. It works. It is sitting right there, humming, and Bungie will not flip it. There is no heroic engineering saga standing between Bungie and Linux players. The vendor already did the work. Bungie simply keeps the light off.

And look at where the studio is standing while it does. Marathon launched in March 2026 to a shrug and a scattering of praise, and its player counts have been draining ever since. Season 3 is delayed. The strict seasonal schedule is being dismantled. There is a promised pivot toward PvE, with the Symbiosis update in December 2026 and a major drop in March 2027. Over on the Destiny 2 side, the story reads like a morgue report: layoffs, a walked-back plan to end development, and a recovery tour that now includes restoring vaulted content.

So here is the portrait. A live-service game with a shrinking audience, and a studio refusing to open the door to an entire platform of players. Not because it cannot. Because it has not chosen to. Standing in the middle of a house fire, holding a hose, admiring the water.

The Switch Is Right There

Nobody is asking Bungie to port an engine. Nobody wants a bespoke Linux client or a rewritten netcode miracle. They are asking the studio to opt into anti-cheat support that already exists, on a platform Valve has been sharpening for a decade. Flip it. Test it. Then watch a chunk of the Steam Deck install base that already wants to play your game walk through the door you have been bolting shut.

For a game in Marathon's condition, that is not a nicety. That is new players, for free, at the exact hour the studio needs them. Every month Bungie leaves the switch down is another month of a thinning matchmaking pool, a quieter launch for the December update, and a smaller room full of people who might buy the next thing.

And I will say the quiet part in plain daylight, because nobody else seems to: I like Marathon. It is a game for adults and for patient people. Its art direction is ugly and dystopian on purpose, not by accident, and there is real craft buried in it. Watching it bleed out while the studio sits on an unlocked door is not funny. It is the specific frustration of watching someone you respect refuse the easy thing. At this rate, free to play is not a question of if, but when. That is the lever these studios always grab last, long after the cheaper and better one was sitting there, warm, ignored.

Almost nobody is still talking about Marathon. The discourse moved on. The coverage thinned out. The game is sliding, quietly, toward the point where no amount of marketing drags it back. Which leaves a tucked-away corner of the internet, this one, as one of the last rooms where the name still gets said out loud. Maybe some algorithm notices precisely because somebody bothered. Maybe a dying game finally earns a headline out of sheer stubborn repetition. I would not hold my breath. But I also would not be the first nobody with a blog to accidentally matter.

The Bottom Line

Epic's Linux news is good news, even if it took Valve turning Linux into a real market for Epic to finally look up. But here is what the good news actually does. It sets a bar, and then it exposes everyone still slouched underneath it. Epic, of all the companies on this earth, is now shipping a Linux launcher and rebuilding anti-cheat for the platform. Bungie, sitting on a game that needs to survive, with an anti-cheat vendor that already supports Linux, still will not reach up and flip the switch.

And when it is finally over, when the servers go dark and some archivist of dead shooters asks who was still yelling about Marathon in the last ugly weeks, I want the record to be specific and unflattering: it was a nobody with a laptop on a website the size of a phone booth, at four in the morning, hoarse, and somehow still right.
