There’s every chance you’re still waiting around for someone to whittle your PC copy of Batman: Arkham Knight into a vaguely acceptable shape (or you just got a refund), but if you’re one of the lucky ones for whom the game is playable, you might want to check this mod out.
Basically, the Playable Characters Mod lets you loose on the streets of Gotham as one of ten different characters - that’s either Red Hood, Harley Quinn, Nightwing, Robin, Azrael, Bruce Wayne, Catwoman, Commissioner Gordon, Joker or GCPD Officer Owens.
Not all of those characters have their own combat animations, and Gordon in particular can’t counter at all, but if you want to spend more time pummeling people as Nightwing, Robin, or DLC characters Red Hood and Harley Quinn, here’s your chance.
