Metal Gear's main man huffed on Twitter that he was "sick and tired" of people asking if the games are one and the same during PAX Prime. We guess that's a "no", then.
While I am happy to know people liked "MGS Ground Zeroes", I'm sick & tired of people keep asking me like "is that project Ogre?" here in Seattle everyday. Project Ogre is what the project that Ogre appears. Ogre does not appear in "MGS Ground Zeroes" trailer.
Project Ogre remains a mystery, but at least we've got plenty of time to re-watch that first gameplay footage of Metal Gear Solid: Ground Zeroes while we wait for more information.
