Stealth kills, Ninja action, and repetition.
On the down side. The game is VERY, very repetitive. You'll find yourself doing the same thing over, and over through stages that repeat themselves several times. Which is assassinating someone who's wronged Lord Goda somehow. Occasionally you'll run into a variable, such as collecting bombs, eliminating all enemies, and in one missions tracking Echigoya without being seen. The AI is absolutely awful, your enemies will see you but never really chase you making escaping nothing short of running around the nearest obstacle. There is a large lack of boss fights because you can kill most of the targets by stealth. There is a large variety of items, but you don't get very much use out of them being that all you need is your sword and a few select abilities if you tune your character correctly. The game felt very lazy, so much more could have been done stealth wise to make this game take stealth action to the next level. All in all if you love tenchu, this is another title for you to get your favorite old thrills out of. If you're new to the series you'll find this game hard to swallow. For those of you who are looking for gamerpoints the achievements (most of them anyway) are straight forward and easy to get so long as you have the patience to go through 50 missions on every difficulty.
