Metal Gear Solid: Peace Walker will be Hideo Kojima’s 4th game on the PlayStation Portable, developed by the Metal Gear Solid 4 team, the title is set to be the “Metal Gear Solid 5 inside” Kojima. The game, which is being directed by the gaming legend, is currently known to have two control systems, an action style and a shooter style, but now rumors point to another, even better, system in the game.
According to leaked reports out of Japan, Kojima has said in the Japanese gaming magazine Famitsu:
“There’s an unannounced system that will surprise you. It will make you want to rush out and buy a PSP.”
Kojima is no stranger to teasers, often creating hints to his future projects, that serve only to add more mystery to the web of secrecy that surround his games.
