Added a new element to Konami's brilliant series: Survival.
Third game in the Metal Gear Solid series, and (in my opinion) the best MGS game, because of the great memories with friends, great story, good gameplay and moving characters.
The game takes place 40-50 odd years before the other Metal Gear Solid games, and puts you in the boots of Naked Snake - An American ex Green Beret turned CIA operator who infiltrates a Soviet jungle to rescue a scientist called Sokolov - like the other MG games, it twists and turns greatly.
You use camouflage to hide in the jungle, CQC to eliminate enemy soldiers, and you hunt for animals and plants to fulfill your stamina from time to time.
I urge anyone to try this game, it may be old, and have a sequel out Metal Gear Solid 4: Guns of The Patriots on PS3. But to me, it's the best one in the series.
I recommend Subsistence.
