At one point during its development, Metal Gear Solid 4: Guns of the Patriots was “running beautifully and smoothly” on Xbox 360.

That’s according to the game’s assistant producerRyan Payton, who shares the revelation in Steven L Kent’s bookThe Ultimate History of Video Games Vol 2(viaTime Extension).

PS3 exclusive Metal Gear Solid 4 was once ‘running beautifully’ on Xbox 360

In an interview for the book, Payton claims that there was no exclusivity deal to ensure the game was only released onPS3, and that the decision instead came down to the choice of disc format used inMicrosoft‘s console.

Payton says that at one pointKonamiset up a team dedicated to seeing if the game could be ported to theXbox 360.

“Despite how downtrodden my colleagues were with developing on PS3, most of them were still hardcoreSonyfans and were not in favour of spending resources on such a test,” Payton explains in the book.

“They believed Metal Gear Solid 4 would look and run terribly on Microsoft’s older and inferior hardware.

“One fateful day, the Konami R&D team hosted a meeting where we got to see the fruits of their labour – Metal Gear Solid 4 running beautifully and smoothly on an Xbox 360.”

According to Payton, although the port was possible on a technical level, it wasn’t practical on a physical level.

Because PS3 games came on BD-ROM discs which could hold up to 54GB of storage, and Xbox 360 games came on DVD-ROM discs which could only hold up to 8.3GB, bringing Metal Gear Solid 4 to Xbox 360 would have required putting the game on numerous discs, something Konami wasn’t willing to do.

This was backed up at the time by Sony’s Jack Tretton, who once stated: “Metal Gear Solid [4] is not only exclusive on PS3, it’s only possible on PS3 thanks in part to Blu-ray.”
