This game grows on you and in every way this has to be the best Metal Gear Solid I have ever played.
The new thing about it is the camera - it's very fun to play with, and it can also help you when in bad situations because in the original Snake Eater it was set in a bird's eye view. It was kind of hard to see what has happening around Snake. The new camera is better though - it gives you a close-up when you want one.
The graphics are pretty much the same as what they were in Snake Eater. The music was great, that's all I can say there. The sound effects were of good quality.
Also, another thing I like about Subsistence is to actually play the original Metal Gear and Metal Gear 2: Solid Snake games, and they were the classic games that I had never played before, which came out before the PlayStation's Metal Gear Solid.
OVERALL: This game is one of the best games that has never let me down. It has never had a bad moment. With the new camera in Subsistence makes this a much better game.
