Konami Europe today announced that Metal Gear Solid 4 : Guns of the Patriots has shipped to retail in the UK. The game features an aging and exhausted Solid Snake in the middle of a futuristic battlefield. In spite of his failing body, Snake is equipped with a crucial new device tentatively known as "OctoCamo", a high-tech suit that dynamically transforms its texture based on Snake's surroundings. This new gameplay mechanic allows him to seamlessly blend into the environment, providing him with the means to stalk his enemies like never before.
