Red Dead Redemption is a Western action-adventure video game developed by Rockstar San Diego and published by Rockstar Games. It was released for PlayStation 3 and Xbox 360 consoles in May 2010. It is the second title in the Red Dead franchise, after 2004's Red Dead Revolver. The game, set during the decline of the American Frontier in the year 1911, follows John Marston, a former outlaw whose wife and son are taken hostage by the government in ransom for his services as a hired gun. Having no other choice, Marston sets out to bring the three members of his former gang to justice.
The game is played from a third-person perspective in an open world environment, allowing the player to interact with the game world at their leisure. The player can travel the virtual world, a fictionalized version of the Western United States and Mexico, primarily by horseback and on foot. Gunfights emphasize a gunslinger gameplay mechanic called "Dead Eye" that allows players to mark multiple shooting targets on enemies in slow motion. The game makes use of a morality system, by which the player's actions in the game affect their character's levels of honor and fame and how other characters respond to the player
