Metal Gear Solid 5: Ground Zeroes, the open world prologue to Metal Gear Solid 5 that's headed to both current generation machinery and the PlayStation 4 and Xbox One, is shooting for 60 frames per second on next-gen.

"For current gen we're aiming at 30 fps and for next-gen it's 60 fps," Hideo Kojima told Eurogamer at the Tokyo Game Show.

Kojima's using the show to debut the next-gen version of Ground Zeroes via presentations on Sony's stage, with the demo he showed two weeks ago running on hardware equivalent to the PlayStation 4 and Xbox One.

Kojima expressed some caution about the next-gen versions, though. "This game was originally developed for multiple platforms, multiple devices and multiple generations," he said.

"Fox Engine was created with the current generation in mind. Maybe with other games that are being created exclusively for next-gen it might look a little behind."

The next-gen versions of Ground Zeroes will provide noticeable improvements, though.

"Of course for the next generation the resolution and the lighting will look much better," Kojima said. "Gameplay wise it will be the same - we're trying to make it as close as possible. The gameplay experience won't be affected whether it's next gen or current gen."
