Gears of War 3, Hackers and PlayStation 3
Gears of War 3 was developed exclusively for Xbox 360. Are you sure? A former hacker presented a long gameplay version of the working (with some problems, but still) version on PlayStation 3. As he says, he has no idea why it was developed at all.
A former hacker known as PixelButts posted a long gameplay from Gears of War 3 on YouTube. What's so special about it, you may ask? Well, it was running on PS3. As the user writes, he has no idea why this version even exists and assumes he's the only one who has it. As you can see, this "build" is not complete, with a variety of artifacts and visuals errors that are particularly striking. Also noteworthy is the unstable number of fps and button symbols from Xbox 360 controller. Despite the presence of the latter, the editors of Kotaku managed to get a confirmation from the author of the video (in the form of a screenshot from the PlayStation 3 menu) that it is actually a version for PS3.
