This is very reminiscent of the Crysis 2 PC leak that happened not too long ago. Before you get all mad and upset about not getting a chance to play, you'd need a JTAG XBox 360. If you have to ask what that means, I am not the person to tell you. Over on the NeoGaf forums the community is all over this leaked news. Most of the videos have been pulled down by Microsoft or Epic games already. My question is "Who is actually watching these videos?" Most players want to play the game to play the game, not watch someone else do it on their computer.
If you do not have a JTAG XBox 360 avoid youtube. I mean it. Like the plague. Now, for those of you GoW fans that want to be in the know, and see the latest video that isn't blocked check out the link below. Consider it my gift to you. According to the infamous Cliffy B on Twitter: "Here. Please stop asking me about it. Upsetting enough to hear and making more news about it only draws attention. Sad."
So there you go. Something to salivate over until September. But until then, stay away from youtube! Or watch every second, the choice is yours...
