Middle-earth: Shadow of Mordor is a 2014 action-adventure video game developed by Monolith Productions and published by Warner Bros. Interactive Entertainment. An original story based on the legendarium created by J. R. R. Tolkien, the game takes place between the events of The Hobbit and The Lord of the Rings film trilogies. The player controls Talion, a Gondorian Ranger who bonds with the wraith of the Elf Lord Celebrimbor, as the two set out to avenge the deaths of their loved ones. Players can engage in melee combat, and use wraith abilities to fight and manipulate enemies. The game introduces the Nemesis System, which allows the artificial intelligence of non-playable characters to remember their prior actions against the game's protagonist and react accordingly.
The game's development began in 2011. In order to create an accurate environment and be consistent with Tolkien's books, the developers consulted many people from Warner Brothers, as well as Peter Jackson, director of the film trilogies The Lord of the Rings and The Hobbit. They also received assistance from Weta Workshop, who advised on the special effects. Christian Cantamessa served as the game's lead writer, while Dan Abnett was recruited to write dialogues for the orcs featured in the game. Monolith focused on the development of the PC, PlayStation 4, and Xbox One versions, while the development of the PlayStation 3 and Xbox 360 versions was outsourced to Behaviour Interactive.
