Which collection remastered Arkham Asylum and Arkham City for PS4 and Xbox One?

Batman: Return to Arkham remastered Batman: Arkham Asylum and Batman: Arkham City for PlayStation 4 and Xbox One. The collection brought the two earlier games to newer consoles with upgraded visuals and bundled downloadable content.

Virtuos handled the remastering, moving both titles to Unreal Engine 4. The package improved models, environments, lighting, effects, and shaders while preserving the core stories and gameplay that made the original releases influential. It was released on October 18, 2016.

The title is easy to confuse with Batman: Arkham Collection and Batman: Arkham Trilogy. Return to Arkham contains Asylum and City only. Arkham Collection later combined those remastered versions with Arkham Knight, while Arkham Trilogy refers to a different package containing Asylum, City, and Knight for Nintendo Switch. Batman: Return to Arkham therefore identifies the specific two-game PS4 and Xbox One remaster.
