Metal Gear Solid 4 will feature psychological effects and battles, according to creator Hideo Kojima, who was waxing lyrical at last weekend's GO3 Entertainment Expo in Australia.
Kojima: "To make it very simple, in the past Metal Gears, Snake was going into enemy environments--so everyone apart from Snake was an enemy," Gamespot reported that Kojima said. "This time it's a warzone, so you have country A or country B, so Snake could interfere with either of the countries. It does not necessarily mean that everyone is an enemy to Snake. This creates a new tension in playing this new hide and seek."
Earlier this year Kojima revealed he had a "strong interest" in working on Xbox 360 and particularly PC. However, Konami remained insistent this morning to Eurogamer that MGS 4 was a PS3 title, though a release date and any other specifics were still to be confirmed.
