Microsoft might be teasing an upcoming enhancement for Rocksteady's Batman: Arkham Knight based on an image in the latest Xbox Wire post.
The post, which relates to a new feature allowing you to see which games support your chosen language, feature a screenshot of the Xbox Series X dashboard with a handful of games on it. One of the tiles is for Batman: Arkham Knight, and features a logo for Xbox Games Pass and another indicating it has been enhanced for Xbox Series X|S.
Batman: Arkham Knight is on Games Pass, and none of the other games featured in the screenshot have been incorrectly labelled either. This suggests that Microsoft, accidentally or not, has leaked a potential upgrade releasing in the near future.
Batman: Arkham Knight hasn't received any enhancements for both Xbox One X and the PS4 Pro, so even with the Xbox Series X you're still stuck playing at its native 900p resolution. An upgrade to that would be a nice treat for those wanting to play the game on a 4K display, or perhaps with a framerate beyond its current 30 fps.
Rocksteady is currently working on Suicide Squad: Kill The Justice League, its first game since the launch of Batman: Arkham Knight in 2015. It is expected to launch sometime in 2022. Gotham Knights, a new take on the Batman universe, is currently in development at WB Games Montreal and is expected to release later this year.
