It's a PS3 game from Quantic Dream, in which you control four different characters who all get mixed up with a serial killing case: one is a private eye, one an FBI agents, one is a reporter and one is a dad who's trying to save his son. It's a very cinematic game and uses a lot of quick time events, but the story is good and the choice of freedom is very impressive. There are multiple endings and everything you do affects the game.
Got one or two of your characters killed? No problem: they'll stay dead and you'll just play as the other characters. The story will change but it's still okay. It's really beautiful, while still grotesque. It's actually rated 18 over here which means it's not really for children, which I can very well understand. It's still awesome.
