If you are looking for a game with terrific graphics and a good story, you should try this game.
Still, there is no game without negative sides. Heavenly Sword is very short; you can easily beat the whole game in one day. Other thing that isn´t so good in the particular game, is loading times. If you die, you have to wait for a long time to get back to the action, and that really eats the feeling.
If only Heavenly Sword would be longer and it would have shortest loading times, I would call it as a one of the best games ever. Now, it´s only okay. But it is still worth of playing. It feels good to play and it looks good. And if you don´t care so much about seeing blood, this is a very good alternative for the God of War.
