Epic Games just announced a big upgrade to Epic Online Services, which will now include a full toolkit to enable developers to do cross-play.

Currently, the initial release of the new tools in the EOS SDK supports "PC" (they mean Windows), but they fully plan to support Linux and macOS as well. They already support Epic and Steam directly with more stores coming and consoles / mobile support coming later. EOS includes a special overlay (like the Steam Overlay) that brings together Steam and Epic friends and all the integration into a single list.

For game developers, this sounds thoroughly useful.

What it includes:

  • All friends, one place. Steam and Epic Games Store friends merge into one overlay allowing players to see all friends in a single list.
  • Integrated game invites. In-game, players can search and send invites to friends across Steam and the Epic Games Store, making connecting and playing together easy.
  • Account linking. Onboarding without emails or password prompts. With just a few clicks, Steam players can jump into a game while an Epic Games account is created under the hood for their Steam account.
  • Update-free improvements. When games are installed, the crossplay features are distributed via a self-updating in-game overlay. Players can enjoy new features and improvements without needing to update anything themselves.
  • Plug-and-play SDK. Each Epic Online Services toolset is self-contained, so developers can mix and match the services they want to implement, incorporate the things they want, and leave the rest. Crossplay tools are no different.

Hopefully people will use this over Vivox, which still doesn't support Linux and can be quite problematic with Proton too. Even if you don't particularly like the Epic Games Store, what they offer with Epic Online Services seems pretty great.

Having no EGS friends and not playing mp parts of games, I hope this isn't forced.

Epics "support" of Linux truly has no equal.

I hate the persistent questions in Rocket League (Steam) to export my friends list.

Epic stands for the diablosation (derived from Blizzard's Diablo) of the gaming sector. Formerly good games are adapted to this. If you just give people the games for free, it's clear where the money has to come from. From people who fall for such money grabs. It rarely makes the games better, even if you don't pay.

Normal games are now only giveaways and are devalued.

That's all true and I feel the same, yet if Linux gaming is supposed to grow and maybe even to stay as relevant as it is, we need compatibility with these annoying services and launchers. See the SteamDeck forums for reference. A lot of users already bought into these ecosystems and for them to join us on our lovely OS of choice, transition needs to be as painless as possible. That's why this is good news. It's less of a "I can now" then "Those who *need* this can now use Linux"

No thank you! I had an account many moons ago to help test Unreal Tournament 4. Deleted it when it became clear that they were not going to work on it further. Developments since then, such as casting themselves as the saviors of PC gaming while poaching games as exclusives when they were about to release and NFT nonsense, have contributed to my dim view of them. To me this is just another attempt to buy their way into market share by boasting that they have "x amount of users!" same as they've done with their giveaways.

This is theoretically better than GOG's own attempts given that Linux is claimed to be supported. But, well, seeing is believing. Hope it's actually easy to use and seamless for both devs and users.

Epic's opinion of Linux is made clear in the fact that Fortnite does not have a native Linux version. Not that I have any interest in Fortnite, but it is Epic's biggest game at the moment and the only one they are actively developing. There's also the fact that while Unreal Engine technically does have Linux support, it lags far behind Windows (you have to compile the source code yourself!).

Disgusting methods.
threetwo 17 Jun 2022
awesome, the more compatibility the better
denyasis 17 Jun 2022
Very nice they are adding support! We need more stores with more support. Hopefully they continue improving it!

They're also actively developing Rumbleverse too. And EAC, and Unreal 4/5, and overseeing Rocket League and Fall Guys.

Epic's opinion of Linux has always been that they support it, its comments like these just try to downplay this because it's easier to be negative toward the company than even giving them a little credit where its due.

Also, unless i'm missing something here, isn't the base source code for UE4's code the exact same as it would be for Windows? If anything, that makes it more up to date than the precompiled versions you'd use on Windows/ MacOS otherwise.

Don't get me wrong, Epic really should do precompiled versions of UE4 and 5 for the popular Linux flavors too.

This doesn't change the fact that I won't be supporting them but, I'm glad they'll be supporting GNU+Linux. Newcomers and fans of their games will be able to migrate over.

Epic Game Store doesn't have a Linux version. None of the games they sell are for Linux, nor do they offer their own solution for Linux compatibility like Valve's Proton. Their biggest game has no Linux version. And asking Linux customers to compile their own source code of Unreal Engine with all the complications and pitfalls that are inherent to such a process can hardly be counted as meaningful support when Windows users can simply download the binary and be done with it. I'm also not sure how Epic "overseeing" other projects that also don't have any kind of Linux support helps your argument. When you say that they "support Linux", I think what you mean is that they pay lip service to supporting Linux without actually supporting it.

Bottom line: By their actions, Epic, like GoG, is telling us they really don't care if they have any Linux customers or not.

Yes, well, I'll be significantly less un-excited when they actually do support GNU+Linux, rather than just planning to.
Chronarius 19 Jun 2022
I couldn't care less. Epic "Fail" Games is the worst Company ever. A few weeks ago they got me to create an account with a free "Borderlands 3" and before I could download the game they locked account . Without any information what I did wrong?!?! The only information I got was: Can not be reactivated! What the hell?!?! 🤬

Well, they can keep their 💩💩💩 and rot in hell!!!
