Amnesia: A Machine For Pigs Discussion Topic Part 2

[Bridge]

I can only find a program called AmnesiaKeygen.exe or something similar, and no working download links to anything that could conceivably be the full game. There are sites that claim to have it if you complete some surveys and download a program, but I hope nobody here is stupid enough to fall for that.

What I am interested in however, is whether or not this image is actually from the game (potential spoilers - you've been warned):

Spoiler below!

EDIT:

There is nothing on Pirate Bay, but the most notorious pirate sites like Razor or IsoHunt are offering it, I still do hope this is a hoax.

EDIT: Can someone explain to me, how is this possible, how could it leaked several months prior to release?

Somebody hacked Frictional Games' or tcr's servers? Presumably they need to keep the almost-finished copy somewhere?

And I found a copy on isohunt, but I am unsure of whether it's valid. Regardless, I stay away from torrents so I'm not touching it.
