Towards the end the latest episode of Batman: Arkham Insider, Game Director Sefton Hill answered a few questions from the fans about Batman: Arkham Knight, and some of them provided some really interesting information.
First of all, Hill mentioned that we can expect “a lot of Easter eggs” probably more in this game than “in the last two games put together.” He also added that there are “some really obscure ones” on the side of some that are more obvious.
Hill also explained that New Game Plus will be included in the game. You’ll be able to carry over all of your xp, all of your upgrades, and all of your unlocked gadgets, allowing you to tackle some challenges earlier in the game.
Riddler trophies are also shared between all your playthroughs, so you won’t have to find them twice.
Finally, Hill mentioned that returning gadgets from previous games have new upgrades that give them new abilities. For instance, the batclaw has a new upgrade that lets you instantly take enemies down. It pulls them to you and smashes them down into the ground. For the first time there are also gadgets used while gliding.
