A whole lot of games on the PS4 Pro don’t necessarily run the way they should- in fact, they often end up running worse than the standard PS4 versions. Thankfully, in all these cases, these games also receive updates to remedy the problem right away.
That has also happened with Batman: Return to Arkham. The Arkham City/Arkham Asylum PS4 remaster collection has received a new update on PS4 Pro, which improves its performance, and also makes the game run more stably, adding some more visual upgrades into the mix at the same time as well. So if you want to play Arkham Asulym and Arkham City, there is no better way to play them right now than simply picking them up on your PS4 Pro.
The Batman Arkham series technically ended with last year’s Arkham Knight and this year’s Arkham VR– developers Rocksteady have stated that they are moving on from the games. That said, there are rumors that Warner Montreal may be developing a new title in the franchise starring Damien Wayne in the lead.
