Metal Gear Solid is a title well known to most gamers worldwide. Metal  Gear Solid PW(Peace walker) is literally the longest and largest MGS game to date on both console and handheld. hideo Kojima was quoted as saying prior to the games first release that he wanted to create his largest creation on Sony's smallest system and with PW he delivered. This game boast hundreds of hours of game play, over 150 missions, lots of weapons to find and upgrade, an upgradeable base and crew, and an extensive multiplayer, both co-op and versus. On a side note the game has since been re-released on several consoles and pc  via steam and the multiplayer in online in those versions while the psp version is sadly only ad-hoc. 
   
   As far as game play is concerned, the controls are the same as they are on the other handheld mgs games which means it does take a little getting use to. Missions are fun as you sneak around and know out or subdue and capture enemies to build up your base to get better weapons and gear. Tank battles are pretty fun too. Thing is you don't have to sneak if you don't want too. The game offers several different play styles and rewards you with a title base on how you play.
