The word 'delay' has become somewhat synonymous with the year 2014. The list of games getting pushed back is getting quite long, and now Middle-earth: Shadow of Mordor can be added to the list, although the delay isn't as drastic.
The PlayStation 3, Xbox 360 and PC versions have all been pushed back to November 18 in the US, and November 21 in Europe. The PlayStation 4 and Xbox One versions remain unaffected and will still be releasing on their original release date, September 30th.
No detailed reasons were given, however, the only thing that PR has stated was that "it will take more time in development." Perhaps that means optimizing the game to run smoother on last-gen consoles and the PC.
Middle-earth: Shadow of Mordor delivers a dynamic game environment where the player orchestrates their personal plan of vengeance as they bend Mordor to their will. The game begins on the night of Sauron’s return to Mordor, as his Black Captains brutally execute the Rangers of the Black Gate. Players become Talion, a ranger who loses his family and everything he holds dear, only to be returned from death by a mysterious Spirit of vengeance. Based on the player’s actions with the in-game Nemesis System, every enemy encountered is distinct and can evolve to become a personal archenemy through the course of the game. As Talion’s personal vendetta unfolds, players uncover the mystery of the Spirit that compels him, discover the origin of the Rings of Power and confront the ultimate nemesis.
