A world premiere of Batman: Arkham City is set to be revealed at the Spike Video Game Awards next month. Presumably a proper trailer showcasing its gameplay and whatnot.
Batman: Arkham Asylum was released to both critical acclaim and impressive reception. Praised as the best game based on a comic franchise, it impressed many gamers and comic book enthusiasts alike. Batman: Arkham City looks to take that to the next level with even more gadgets, fluid combat and a whole larger playground.
It'll be out next Fall for the PlayStation 3, Xbox 360 and PC.
