Without any question my favorite Stealth Game of all times.
It got everything you want in a game, an awesome Story, really good graphics (especially for 2005) and it just makes fun. You can play it a hundred times and it won't get boring.
Sneaking with Sam Fisher around the world, from Peru to Tokyo, is extremely fun and I can't stop loving this game, with it's awesome lightning, great characters and a cool Soundtrack.
"In June 2007, tensions are running high between China, North Korea, South Korea and Japan, due to Japan's formation of an Information Self Defense Force (I-SDF). Considering this to be a violation of Article 9 of the post-World War II Constitution, and blaming the I-SDF for information warfare attacks against their countries, Chinese and North Korean forces establish a blockade in the Yellow Sea against Japanese shipping. Because Japan is an ally of the United States, and thus the NSA's Third Echelon, the U.S. Navy dispatches a highly-advanced warship, the USS Clarence E. Walsh (CG-80), to the Yellow Sea with the hopes that China and North Korea will back down at its presence."
If you are into Stealth Games...what am I saying...even if you're not, try it out. It is one of the best Games ever created. I love Ubisoft Montreal for that. It makes me happy, I love it.
You have to buy it. It is worth every single penny.
