The rumors has been true all along! The new Batman game from WB Games Montreal is called Gotham Knights, and you play as Nightwing, Red Hood, Batgirl, and Robin.
Checkout the official trailer:
The game looks like it takes place after Arkham Knight after Bruce dies. Anything with Nightwing is an instant sold for me because he is one of my top DC characters. The gameplay looks great and the graphics look topnotch. Also, can’t wait to fight against Talon!
