Metal Gear Solid: Ground Zeroes is neither Metal Gear Solid 5, or Kojima's long-teased 'Project Ogre', CVG sources have suggested.
CVG claims that a source close to the matter has claimed that Project Ogre is a codename for what is believed to be Metal Gear Solid 5, not Ground Zeroes.
Unveiling Metal Gear Solid: Ground Zeroes at a 25th anniversary event last week, Kojima revealed that he is currently working on more than one FOX Engine project - one for current gen, and others for next-gen. Ground Zeroes is the current-gen project.
That also leaves Kojima's Zone of the Enders project and - if CVG's source hold up - Metal Gear Solid 5. Kojima also confirmed that Ground Zeroes is a prologue to something bigger - possibly MGS 5 again.
