Everything is short in training and multiplayer, but it takes a long time to complete Medium, hard and extreme mode.....
Story:
Well.... There is no story.... Anyways I was just kidding. Anyways, about metal gear solid's story, instead of putting yourself into the battle, you have to collect units along the way. Real good eh? In Portable ops, its between you and yourself aka the radio, but now, its different. You got friends along the way. Well, I like the part, but I wish there was cut-scenes. 9/10
Gameplay:
Kinda good, the graphics are awesome. The camera is good, and I like the mode. At least every character has a skill of whatever they are good at, and it may depend. One thing that Konami did not add is blood, comparing to Medal of Honor, Allied Assault. And another problem is that you cannot "Save your game" that you could play the next time. Instead, put your PSP to sleep mode, and charge it when you go to bed. 9/10.
Sound:
Exact same thing from Metal Gear Solid 3, except that the cut-scenes should have sound. 9/10
Graphics:
They look awesome. It reminds me of MGS3, but different. 10/10
Rating: 9.3/10 - Scoring: 9.5/10
Classification: Could make you lose sleep, so I suggest play this in the morning, it will take you about 10 stages, but may depend. Multiplayer is real good, even with single player, so this game is "A VR mission" to play in.
