When I got peace walker, it was mainly based on the reveiw by IGN, who's reveiw made the game seem overated with its constant praise, but it turns out, it was very deserving of that praise.
This is a great on the go stealth sci-fi, the gameplay is top notch and there are several controll types for people who prefer to do things their own way.
As a noob to the metal gear sereis, I thaught I would not understand the storyline, but unlike some metal gear solid games, this one actually made sence. This game's story could be a stand alone title, as the flashbacks and references to other titles would fit in even if this was the first.
The visuals and audio are fantastic for a psp. You can sneak around the jungle holding people up and kidnapping them instantly, or you can choose to take on a tank in a train yard, this is however set in an area near to the equator, so the main of the environment will stay the same untill you near the end of the story ( that took me 17 hours to complete, not including the fantasticly laid out extra ops missions). The audio is fantastic, there was a part when I had to listen to find a birdsong and I realised how outstanding the audio was and as for the visuals, there were areas when I completely thaught this game updated my screen
This game focuses heavily on co-operation (2 players). This will be a pain for british users as PSPs are not very popular here, but there is a little thing called AD-HOC party for the ps3, which creates a server so you can play online with people. This may eventually become the case because there are a few weapons and items which can only be used with 2 or more people, and the missions are very difficult to play alone. AD-HOC party is thankfully free, so if you have both systems, this is greatly recomended.
Parents do not worry, there isn't any blood, guts or gore in this game, and it genraly discourages violence. The rating is there for a reason, but it is quite a soft 15, and is only there in case a player is not to stealthy.
Another thing I would like to point out is that this is not a shooter. If you want a shooter game then turn around, this is one of a stealth series, which punishes players that run through and ignore the main aim, and you will also be frustrated by the guages and colours that appear that are to do with stealth. If you like the splinter cell sereis however, you will enjoy this.
Other features difficult to mention however, are making your own gigantic robot, and developing your own base in the sea so you can make those exclusive weapons I was talking about.
Once you pick this up, you won't want to put it down
