Gameplay and screenshots from a canceled Batman game set in the universe of Christopher Nolan's Dark Knight trilogy and developed by Monolith Productions have leaked online. The leaked footage and images, which were posted on Twitter by Dageekydude with information learned from DidYouKnowGaming, Andrew4586 on Twitter, an internet archive, and some developer portfolios, showcase a game that reportedly eventually became Monolith's Middle-Earth: Shadow of Mordor, nemesis system and all. 

Codenamed Project Apollo, this Nolanverse Batman game would have featured the likeness of Christian Bale's Dark Knight, the "Tumbler" Batmobile, plenty of gadgets, and a unique spin on the Caped Crusader's detective work. 

The thread starts below with a look at Batman and the Tumbler. Dageekydude then shows off how Batman would have traversed Gotham by gliding and with the use of a grappling hook, and it's not that dissimilar to Rocksteady's Batman: Arkham trilogy of games' traversal. Players would also be able to drive around using the Tumbler as well, apparently. Check it out below: 

The open world of Gotham could be traversed by either gliding and utilizing the grappling hook (as established in the Arkham games) or by operating the Tumbler/Batmobile. pic.twitter.com/VZKXJBFsgP
