Do you have to complete it before the main story is finished? As I'm almost done I think.
What are people's opinion on series ranking? I've played Arkham Asylum and City, but haven't tried Origins or Knight. Which one is better of the 2?
I would say Asylum for me, I think in the move to open world it lost something.
That's not to say City or Origins is bad, in fact I agree that the Deathstroke fight in Origins is nothing short of brilliant.
I finished the game yesterday, I've done everything else except the firemen, dead body, Azrael and Joker.
Getting a bit bored of just driving/gliding about waiting to spot something or hear something on the police scanner though.
WB just removed Denuvo now on Steam 157MB update or 11.5GB update depending on your current install!
