Metal Gear Solid: Peace Walker is an action-adventure stealth video game developed by Kojima Productions and published by Konami for the PlayStation Portable in 2010.
The story begins in Costa Rica. The year is 1974, ten years after the events of MGS3. An unknown, well-armed army has invaded the helpless country and brought a nuclear-missile launching capable giant AI-controlled machine called “Peace Walker”. Some other AI machines along with them. Big Boss, the hero of MGS3, has the mission to save the country and his mercenary unit “Militaires Sans Frontieres” (Soldiers without borders). The plot is good and has some pretty good twists, although it isn’t as good as in previous games. It still beats the usual stories of PSP action games. You must play MGS3 through so that you can understand the game. Otherwise, you’ll be entirely lost. MGS: Portable Ops isn’t really needed, although it’s a good game too.
If you have played Portable Ops, you probably remember a system for hiring soldiers to your base. You had to drag soldiers to a truck that was usually in the corner of the map where you started the level. It was pretty frustrating to remove them there from the other corner of the plan. The recruiting is still there, but it has been significantly enhanced. Now you use an item called “Fulton Recovery.” You attach a balloon to a soldier, and he flies to the air with your friend in a helicopter.
You have a limited number of Fulton recoveries permission, but it’s usually enough. You can hire the recruited soldiers to combat, research, develop medic, and spy teams. The game is also now mission-based. There are a few dozens of story missions that last together for about 17 hours. Then we have “Extra Ops.” There are incredibly many, 128 extra missions that unlock while doing old ones and main ops. It took me about 150 hours to clear all the assignments, making this the longest PSP game I’ve ever played and one of the most extended games on the PSP system.
There’s also a ranking system. The ranks are from down to top C, B, A, and S. By getting S-rank on missions. You sometimes get rewards like blueprints for a gun that your research and development team can make or new camouflages, etc. The game has dozens of firearms, and they’re all a little different from each other. There are also many different camos. You select a camo at the start of the mission, and it’s wise to check out where the mission’s located (mountains, forest, etc.) before selecting your camo. Some camos have special effects too, like your footsteps don’t make any noise, and you can knock people down by rolling into them.
