Why not just expand on the winning formula for the original Arkham games? Do a forty year time skip and have the player as Terry instead of Bruce. Call it Beyond Arkham. It would probably print money if it's as good as Knight or Origins, to say nothing of how much they would get if it was as good as Asylum or City.
The animation looked nice but it clearly has nothing at all to do with the game and doesn't tell any story whatsoever. I really dislike these pointless teasers.
So....do we play as a rat? Because that's all there is in the trailer, and it's not even game footage.
This is a 'trailer' that could have been a news release.
