Exactly what I'm sayin buddy... it could be an exploit to somehow get a connection to a LAN computer. Either that or this guy is really good with after effects, I mean with todays technology, you could possibly just add a video to another video, consdering the camera is in the same exact spot, it could be a possibility and after he clicks on mount game he could have changed the video.
As many have stated... the video is way too broad and not too much detail was represented. When people upload, they have to see that there's tons of criticism and you can't just post videos and expect people to believe it right off the bat, prove us wrong and show us that this video is infact real. If your gonna release an article about your success, then you need the evidence to back it up.
