Metal Gear Solid: Ground Zeroes definitely isn't Project Ogre, Hideo Kojima has confirmed. He also wants you to stop asking him what it is.
Kojima tweeted his displeasure at fan questioning while at PAX Prime in Seattle.
He said, "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."
So there you have it, Metal Gear Solid: Ground Zeroes isn't Project Ogre, shadowing CVG's report this morning that it is, in fact, Metal Gear Solid 5.
We'll have more as it happens, but for now, visit our Metal Gear Solid: Ground Zeroes all access page for every rumour, fact, screen and trailer from now until the game comes out.
