Leaked game files show Xbox One may run Windows RT apps

Xbox One game files leaked in February may have been showing us that the Xbox One is capable of running Windows RT apps all along. A screenshot of Homefront 2 files shows the launcher executable alongside a Windows RT AppsManifest.xml file.

It is not quite news that Xbox One games can be built as Windows 8 apps, and run on Windows as a platform, however today's revelation, highlighted by Justin Angel on Twitter, seems to have excited more developers who will find it even easier to port games, and make the most of the Xbox One's recently announced self-publishing platform. Microsoft first hinted at support for Windows 8 apps at Build 2013: 

If you want to know about how to get a head start about thinking about developing for Xbox One, the logical thing to do is go build Windows 8 applications.

While screenshots like these can be forged, the original source, SuperDaE, has previously been reliable when handling similar leaks. The screenshots first came from Kotaku, who spoke to this hacker, responsible for detailing developers' secret operations. He has since been chased down by police, and has refused to corporate with the authorities.

The Xbox One has been under much controversy since its launch, as Microsoft have been forced to backtrack on certain policies, and rumours suggest games will be 50% less powerful than PlayStation 4 games. The launch is expected by the end of this year, so we must now sit keenly in anticipation until then.

Shouldn't the Xbox One run Windows 8 apps as opposed to Windows RT apps (although they are both "modern" apps and both will be identical)? The Xbox One has an x86 architecture. Windows RT apps are designed for the ARM architecture. What I think you should really say is that the Xbox One is capable of running modern apps.

Its about the Windows Runtime, not really Windows RT
Windows Runtime (or WinRT) apps run on both 8 and Windows RT. And the XBO will come with Windows 8.

Can be very confusing.

Oh my God, please no... Win RT apps are rubbish at best...

I could be wrong but I would imagine that's because there aren't that many users to justify the cost in development time. If you start to add the millions that will more than likely buy an xbox and with win 8.1 a more positive OS then dev's may start to put the effort in.

I disagree but even so, its stil awesome. It isn't just that it could run the current selection of modern apps. It means it runs the same apps as Windows. Making your Xbox a real living room PC. As someone who doesnt game all that often, and has Windows 8, this could be the selling point that convinces me to get an Xbone.

However Windows RT is for touch while X1 is not.

May be if MS manages to mimic the touch screen using Kinect but, i doubt that MS will do that.

We're talking about modern apps here, those aren't just for Windows RT but for Windows 8 as well. True enough they are build for touch first but they also work with keyboard & mouse. So a controller could work out of the box.

However I suspect Microsoft will have a 'Xbox vertified' label for apps that are build to work flawless on Xbone as well. And why wouldn't they use Kinect for this? Kinect 2 is accurate enough to see hand movement and gestures. So you could make swipe moments to browse through an app and push movements to select.

Guys, they all but flat out said that the Xbox One will run WinRT apps at BUILD. They showed a game running then it's code and at the top it had Xbox calls. WinRT is what indies will use to self publish apps and games to the Xbox Store like they do now on the Windows store, and basically on WP as well.

The end game has always been to write once and run anywhere, and though they're not quite there yet, around 90% of your app/game code on WinRT can be shared between Windows, WP and looks like Xbox One as well. With 8.1 and probably 8.2 next year that could be very close to 100%.

"He has since been chased down by police, and has refused to corporate with the authorities."

why would he want to start a corporation w/ the police?? or did you mean cooperate? lol

Huh? How is this ever been in doubt? It's running Windows 8 or 8.1 64-bit Kernel and running the same API's so of course Windows RT API apps will run.

Sometimes, I don't know about you guys. News at 11, the Sun will come up tomorrow! Really?

Come on NeoWin, let's get it together.

What about the game having an "AppxManifest.xml" file means it's Windows RT?

You're right, but for the wrong reason.

What AppxManifest.xml really indicates is that the Store infrastructure is being reused. As you say, it does not necessarily indicate that WinRT is being used.

Microsoft appears to be using AppxManifest.xml as a package metadata format in non-WinRT contexts. For example, Office 365 has a file called AppxManifest.xml, even though it is a non-WinRT application. If you look inside the file, 99% of the XML tags are from a different namespace (appv rather than appx). Only the metadata -- name, description, language, etc. -- uses the default appx namespace.

This suggests that the Store infrastructure may be leveraged to sell Office 365 at some point in the future, or at least that Microsoft wants to future-proof against that possibility. Similarly, it suggests that the Xbox One Store will leverage the Windows Store infrastructure.

To prove that Xbox One will run WinRT apps, we would need to see proof that one of the DLLs is calling into WinRT APIs.

Now, as for what you said about Windows application manifests:

Anaerin said,

Standard Windows applications (can) use an AppManifest.xml file: http://msdn.microsoft.com/en-u.../aa374191%28v=vs.85%29.aspx

Actually, standard Windows application manifests are unrelated to WinRT package manifests. They use an entirely different XML schema from WinRT package manifests. They also do not use the AppxManifest.xml filename (note the "x") -- as stated on the MSDN page that you linked to:


The name of an application manifest file is the name of the application's executable followed by .manifest.

Didn't they already claim it will run both Windows 8 and Xbox OS?
And with Windows 8 automatically comes RT apps?

EDIT: Oh its actually being mentioned plenty below here

I know right, I see this article make the exact same mistakes as the fools on NeoGAF. WinRT = Windows RunTime (which this is about). All current MS platforms will support WinRT as it is an easy way to make multiplatform programs.
Windows RT is Windows on ARM hardware.

WinRT != Windows RT.

The article needs to make this clearer though.... The title needs to be changed to "Windows Runtime" apps. Windows Runtime is often referred to as WinRT by Microsoft. Where as Windows RT is a OS. Confusing i know, but thats MS for you.

So just to make it clear to people... Windows Runtime is the environment that all Metro apps use on both Windows 8 and Windows RT. It's also what the Xbox One will use for apps.

The Xbox One has been under much controversy since its launch, as Microsoft have been forced to backtrack on certain policies, and rumours suggest games will be 50% less powerful than PlayStation 4 games. The launch is impeding, so we must now sit keenly in anticipation until then.

50% less and 50% more are two totally different things. Ps4 is rumored to have 50% more raw power, not xbox one is rumored to have 50% less power. 1.2tflops + 50% = 1.8tflops. 1.8tflops - 50% = 0.9 tflops. xbox one is 1.2, ps4 is 1.8

That is just meaningless nonsense as well.

of course it is. current progress shows the opposite happening. xbox one games running at 1080p60 beautifully while ps4 games running sub 30fps with bad image quality. source:digital foundry

What "real world" tests are you talking about? The ones Eurogamer did the other day by using approximations of the hardware? Yeah, they don't mean jack.

Not that I'm disagreeing with you here, I don't think we'll see a huge difference between the consoles, but claiming that "real world" tests have been done is just ludicrous.

Real world specs show a significant difference.
