Revealed back in February to release in August, Middle-earth: Shadow of War has been delayed to deliver the "highest quality experience." The announcement of the game's delay came from the Warner Bros. game forums and came with a note that the release date in some territories, including Australia, New Zealand, and Japan will have a different release date.
The new release date has the game releasing this year on October 10th. The delay is quite sudden but puts the game in line with Project Scorpio's Fall/Holiday release. The developer has already noted how they are experimenting with the Scorpio so it wouldn't be too much of a surprise to see the game become a Scorpio launch title.
"Middle-earth: Shadow of War expands gameplay in every dimension, including the massive open world, the story, the RPG systems, and personal player stories of the Nemesis System. As with Middle-earth: Shadow of Mordor, Monolith is committed to delivering the highest quality experience. In order to do this, we have made the difficult decision to move our launch date to ensure that Middle-earth: Shadow of War will deliver on that promise.
"We understand that it might be disappointing to have to wait a little longer for the release and are sorry for the delay, but we are working hard to make an amazing game. We’re excited to show more at E3."
The silver lining here is that the Shadow of War will be shown off at E3 2017.
