This is the story of an evil ruler, Bohan who is on a quest to collect mystical weapons as trophies. He will slaughter all who stand in his way. This quest leads him to the clan of Nariko and her people. They have been guardians of the Heavenly Sword, once wielded by a deity and known to claim the life of any mortal that uses it. Nariko is the daughter of the leader Shen and tasked with protecting the sword. When given the choice between handing the sword over to Bohan or surrendering her father's life, Nariko decides to use the sword instead. She is helped along the way by Kai, a catlike woman that is an expert with a bow that is a lot like a mini gun. When Nariko ultimately loses the sword she must fight to not only regain it but also save the lives of the rest of her clan.
This game is perfect in every aspect. It is a wonderful and layered story. As such, even though you know the ending you will want to revisit it often. The animation, especially on the PS3 is phenomenal and I can honestly say that in the cut scenes I have not seen the equal, even to this day. Ninja Theory designed the crap out of this and the best feature they came up with is the after touch. This allows you to slow down projectile weapons and by tilting the controller direct them where you want them to go. This comes in quite handy with the catapult and the bow.
I have played through this game more times than I can remember and it is the only reason I still have a PS3. Everyone that I told about this game and let borrow my copy ended up buying their own. Yeah it is that good. If you have a PS3 still and have not yet played this, then do it. If you do not have a 3, go get one along with this game.
