Kojima Productions has said the PlayStation Vita doesn't have enough power to handle one of Metal Gear Rising: Revengeance's key components.
The spin-off features a free cutting system that gives players the ability to slice enemies in any way they wish. However, the Vita can't cope with the mechanic as it doesn't have enough power. Kojima Productions creative producer YujiKorekado said:
"As of now we aren't considering a Vita version. The reason is one of the main appeals of Metal Gear Rising is this option of the free cut. That requires a lot of hardware power, which is only possible with the power of a PlayStation 3 or Xbox 360.
"So as of now, we haven't contemplated bringing it to handheld consoles."
When asked whether Rising would offer any of the stealth or no kill challenges featured in past Metal Gear installments, Korekado confirmed a special in-game challenge that challenges players to kill enemies by delivering the least amount of damage possible.
