It's not revolutionary but it is close to it. About as close as you can get. It's Incredible Action Adventure game.
Story:
The story of Rapture was great but what dissapointed me was that it didn't tell basically anything about your charactor. His name I heard once and I think it was Doyle. But still I love the story about the city of Rapture.
Sound: The sound is abosolutely the best I have ever heard in a game. The voice acting on the audio diaries sounds so real that you coudn't tell the difference if the person was acting or not. The music did seem a little to old but it was still good.
Graphics:
Awesome. There are a few bad textures but it does look great especially the city of Rapture. That city looks beautiful.
Entertainment:
One of the most exciting and grusome Action Adventure games you will find. Melee attacks are sadly more fun than shooting your guns. I wish that there were more boss battles. There is only about three or four and all of those bosses are easy to defeat. The last boss is definetily a dissapointment if you are one of those that is looking for a challenge. But the boss thing is minor and the game easily does a great job of making you have fun
Overal I would recommend this game to anyone that likes action games. Go out and BUY IT TODAY!
