First piece of news I've seen since opening my PC this morning. Aparently it was a human error on Microsoft's end which resulted in everyone that signed-in for the new dash upgrade also got this.

Here's the oficial message on BioWare Social Network (aka forums) :

EDIT: Some screenshots and videos (damn amazing stuff they've got !) : http://www.neogaf.com/forum/showthread.php?t=451016

So, first thing that comes to mind : has anyone gotten a hold of the leak ?

Nope i would like to get it, i'm in the dash preview but did not read about it until after it had been taken down sadly.

Anyone know if the code was compiled with the demo flag? If so, anyone should be able to run the files.

I hope I'm misinterpreting what people have posted, but apparently EA has taken down the beta server rendering the demo useless (my interpretation is MP and SP. Controlling SP with a server doesn't seem right though...)

I heard that some server had been taken offline rendering it unplayable.

The demo could be modified though making it playable on Jtag or Reset Glitch hacked Xbox 360.

Someone is uploading it to me, its not going to be done for another 12+ hours though. If no one has done so before then ill upload it to the BA FTP.

I wouldn't be surprised. According to EA's EULA, their programs "call home" sending usage statistics and platform information (PCs only I believe; wouldn't make sense for consoles). You also probably have to register with Origin, so to a certain degree your entire game is hooked up to their servers, regardless of MP or SP.

Hell, if anyone'll get it working on jtag'ed xbox I'd be so jealous... (still in warranty and don't want to lose it)

there's ways to get around that i suppose, if they got the source code someone could modify it

Has there been any confirmation if this requires the new dash to run? I know that modifying flags and resigning/rehashing some stuff in programs like Modio can open the door for a lot of fun things

The only way that could ever happen with this type of system is if an employee purposefully uploaded the code, build tools, and assets (which would, in all, be much larger to this) to ruin his career and go to jail. That would also only make sense to release to PC's not XBOX's anyways.

I heard the news on Neowin that BioWare pulled the game off XBOX Live and apologizes for the leak.

and apologizes for the leak...

Shouldn't they be apologizing for pulling it off.

BioWare apologizing ? Judging from their forums it was MS who "messed" it up.
Also, it seems that you have to pass through a EA login screen before even entering main menu, so unless someone can spoof a Origin server we're out of luck.

Then again, I'm hearing lots of people who argue that this leak has had a bigger impact than any marketing efforts up-to-date.
Someone should do some cullings inside the marketing department (starting with Mr. Awesome Button).

the whole thing could just have been a gimmick to bring more attention to me3, making more people want to buy it haha

Wouldn't be the first time he he...

So was anything substantial leaked?
Game files?

The entire game (in whatever dev stage it was) leaked. Sadly you had to be authenticated by EA's servers before even entering the game. When the leak was discovered, EA pulled the plug and whoever still has the beta is left with a useless app (unless someone hacks it).

Which I seriously hope they do as their is probably some real treasures in it

Well, its probably the only leak of Mass Effect we'll ever see, at least as far as Cmd. Shepard's story is concerned. JTAG'ed dudes will probably have a higher chance of breaking into main menu.

ME3, really the only game I'm looking forward to after DX: Human Revolution. I remember the good ole days at the bioware forums and how most everyone was recently up in arms when the underwhelming Dragon Age II was released.

take a look at this unready cutscene of ME 3:

Where is this leak..? I don't see any link...

It's on our FTP which you don't have access to.

What i should do to have that access..?

Read the Contribution Rules...

Wh..wait.. we have it on the FTP ?! Damn ! Does anyone know how big it is, content-wise ? Is it just the Earth intro and Sur'Kesh ?
