The basic point of this game is to remain unknown. Never be seen, never be heard, kill and hide the evidence. This game is full of hard levels, that are exceptionally fun to figure out how to be the mastermind. I personally suck at being obscure and hidden, I always end up having to kill whoever's in my way instead of sneaking by. But it's up to you to decide the best course of action and save the missing agents, which makes the game all the more free and in your hands. What I like about this game is that the shadows are your best friend. If you want to keep yourself safe and undercover, everything you do has to be covered up and hidden in the shadows. Plus, Sam Fisher, the spy, can do a whole load of special moves, like land quietly or go down zip lines with ease. The ruffle of leaves will determine whether or not the guard heard you, and if you don't do a certain part of the mission needed, you start all over. But that's okay, because the game is great fun. I recommend it, anyone but anyone can find this game awesome.
