10 Rarest Video Game Costumes NOBODY Unlocked

Metal Gear Solid 4: Guns of the Patriots has a very fun costume to unlock; a costume that started as an April fools joke from Hideo Kojima to the fans.

The outfit in question was the cloak and hood worn by famed assassin Altair from Assassin's Creed. This joke then quickly became reality, much to the delight of fans everywhere, when Kojima actually placed Altair's cloak in the game as an unlockable outfit.

To get this marvellous outfit added to the collection, you are going to have to undertake quite the task.

Firstly you'll need to beat the game under any difficulty that pleases you, which sounds easy enough. Alongside though, you also have to perform 50 kills with the knife, perform a CQC hold on 50 different people, and finally, the real challenge of getting 24 or fewer alerts, all in a single playthrough.

Do all of this and you will be rewarded with the outfit after the credits finish.
