Metal Gear Solid 4: Guns of the Patriots, the stealth action game launched exclusively for the PlayStation 3 console was released on the 12th of June 2008 and it is already considered one of the biggest hits of the year. Having in mind that it is the last Hideo Kojima game in the Metal Gear franchise (or so he says), you can imagine it is a masterpiece.

Even though Metal Gear Solid 4: Guns of the Patriots has received a lot of positive reviews from the press, the game was highly criticized especially for the length of cutscenes: there were even rumors (denied afterwards) that we can get 90-minute long cutscenes! All in all, this Konami title brings a lot of gameplay and excitement to its fans and it is probably the best PS3 exclusive Sony has at the moment.

We know that true gamers play all these games just for fun, as they should and not in order to achieve specific point landmarks to prove their friends they are very cool, but we also know that sometimes you just can't live without achieving everything possible with a title you really enjoy. If that's the case and you want to know exactly what to look for, we have prepared a full list of unlockables. Good luck!
