VGA had a trailer for phantom pain from unknown developers moby dick studios. But could this be all a lie? Time to discus!
In the words of many believers, IT'S A CONSPIRACY! I haven't played MGS in a while, though. I miss Portable Ops LAN games.
I can see it being a metal gear game and the is a lot of hidden stuff. I played all of them and beat all but mgs2. Could it be big boss? Personally I think no. Ground zeros is about him and 2 games about 1 guy at the same time does not make sense with a huge character list. Plus big boss never lost an arm unless he is dreaming it. Some people claim that it is big boss and his arm gone because of the cloning DNA of the 3 snakes. But in timeline the cloning happened between mgs po and pw.
Its not two games. They just want you to think its two games. Its just Hideo and team having fun as usual. Not to be taken seriously. Hideo Kojima was at the VGAs and there was no MGS announcement, just that Phantom Pain. I think the whole missing arm thing is a reference to Liquid/Ocelot. Again, its just a fun video like this one: MGS4 trailer - E3'05 - Raiden vs Fisher - YouTube
