Warner Bros. and developer Monolith's upcoming attempt to make you a heroic Nazgul, Middle-earth: Shadow of Mordor, is apparently coming along well enough to earn a rare release date bump: instead of October 7, the game will release on September 30 for PlayStation 4, Xbox One, PlayStation 3 and Xbox 360, followed on October 2 by the PC version (via Steam).
The game's PR team says that's because of "fans' excitement." I'm speculating, but I'd wager the more likely reason is that Tuesday, October 7 was a little crowded. On that day, we'll see major releases like Driveclub (PS4), Alien: Isolation, NBA 2K15 (the latter two for PC, PS3/4 and Xbox 360/One), NBA Live 15 and Project Spark (Xbox One). That, and two days prior, Activision's Skylanders Trap Team hits. So I'd wager Warner Bros. and Monolith backed up to September 30 because it's wide open: the only major rival that day is Forza Horizon 2 (Xbox 360/One).
Middle-earth: Shadow of Mordor is about zipping around Tolkien's "land of shadow" just after Sauron (nee The Necromancer) shows up and wreaks demigodly havoc. You play as Talion, a raised-from-the-dead ranger who can thus tap the same sort of eldritch otherworldly powers the Nazgul could (and since this is a game designed to make you feel ridiculously formidable, plenty more besides).
The twist involves something called the Nemesis System, which is developer Monolith's way of making its world and the things you encounter in it feel procedural. Each adversary you encounter has unique attributes that feed an elaborate ecology of behaviors, and your encounters ripple through that ecology, changing your relationship to other enemies and ultimately creating your own personalized bosses. Every time you play, that deck reshuffles.
Whether the reshuffling feels lively and organic in the playing or too obviously generic remains to be seen, but expectations are high, as they ought to be, given the level of affection and esteem for Tolkien's world.
