Red Dead Redemption is an open-world adventure game, set in the Wild West at the beginning of the 20th century. A well-defined main character and a strong narrative provide the structure for mission-based progression through the adventure, but the sandbox-style game world allows players to explore and interact as they wish, moving from town to town through the harsh wilderness on horseback, by stagecoach, or on a train. Throughout their travels, players can hunt and skin wild animals, gamble, capture bounties, engage in duels, search for treasure, and help those in need. The game is built on the same Rockstar software engine that runs Grand Theft Auto IV, and the user-directed action-adventure playing style is similar to that of GTA4 as well, although the setting is very different. More of a successor than a direct sequel to 2004's Red Dead Revolver, Redemption puts players in control of a former outlaw looking to make good. John Marston is on a mission to bring an old ally to justice, and perhaps to bring a little law and order to the outposts and boomtowns he passes through along the way. Marston once rode with a gang of outlaws who robbed trains, held folks for ransom, and killed nearly anyone who got in their way, to take whatever they wanted. Now, as part of a bargain to protect his own family back home, he must use his violent skill set to apprehend or gun down a former partner called Bill Williamson - a bandit at least as ruthless and deadly as Marston ever was. The "Game of the Year" edition includes the full original game, the zombie-themed Undead Nightmare Collection, the "Legends and Killers" and "Liars and Cheats" multiplayer packs, the "Outlaws to the End" co-op mission pack, the "Myths and Mavericks" bonus pack, the "Solomon's Folly" single-player gang hideout and challenges, and all of the pre-release pre-order content.
