Red Dead Redemption is story set in 1911 when the wild west is dieing. In the story you’re playing as a bad-ass cowboy called John Marston, a former out-law that is trying to go straight but his past simply wont let him. Carrying on in the story the government are blackmailing him by taking away his wife, Abigail, and his son, Jack. They wont let them go until John kills all of his former gang members. So he makes friends with the Sheriff and they create a posse of their own. They start to hunt down the gang. A character they find on there way is Seth, a man that is searching for a map of a unknown mystery.
Red Dead Redemption is a free world game, so you can roam the wild west. You can choose to be a nice guy that means no harm to others… or you can be a cruel, evil, manipulated murderer. But like in Grand Theft Auto if you kill someone you will be wanted, but in RDR, you can either kill or pay the witness to not tell the cops/sheriff.
