Metal Gear Solid: Ground Zeroes director Hideo Kojima has revealed at the Eurogamer Expo that the Mother Base mechanic seen in Metal Gear Solid: Peace Walker will be appearing in Metal Gear Solid: Ground Zeroes. The base allows players to develop weapons and equipment, hire personnel, and even expand the structure itself.
According to Kojima, “We liked the concept of developing weapons and creating new things at your base, and how that influenced the gameplay. That was a really cool idea, and something that was very popular."
However, instead of just being a menu screen, the Mother Base will become an area that players can wander around.
"I can’t reveal too much about what happens after you get in your chopper, but you get in and fly to your base. Then you can walk around your base all in real time,” Kojima described. "It's the base that you create. But if you want to focus more on the main missions, you can do that, so you don’t have to customise the base if you don’t want to."
Kojima also revealed how the helicopter will work in the game.
“You can call in a chopper anytime, anywhere you want, and the way the game system will work, is that when you call in a helicopter, you can return back to your base, or head to another mission. It is also possible to use helicopters for support as well,” he explained.
The game will also feature a day/night cycle. "Later on in the game, time will pass in real time, so depending on how you travel between one stage to the next, that travel time will affect the time of day when you arrive at your destination.”
