UPDATE 30/06/2015 6.48pm: Arkham Knight's PS4 leaderboards are back!
That's the good news. The bad news is that your high scores attained while the leaderboards were down aren't included.
UPDATE 29/06/2015 8.40pm: Batman: Arkham Knight game director Sefton Hill has addressed the matter of the PS4 leaderboards on Twitter, where he's ensured us that developer Rocksteady is working on it.
"Fix hitting soon for the PS4 leaderboards not displaying," he wrote.
He followed that up by addressing concerns that the developer was favouring its console audience over its suffering PC users who are in a more dire need for a fix.
"To clarify: PC is top priority for engine team but there'll still be updates for consoles too. Not all issues are fixed by same people," he added.
ORIGINAL STORY 26/06/2015 5.35pm: Batman: Arkham Knight's online leaderboards aren't functioning on PS4.
They've been down on PS4 since Wednesday night PST. Initially I believed this was just my internet being wonky, but it turns out lots of folks are having this problem globally. GameFAQs, Reddit and the PlayStation Forums are full of users experiencing the same thing.
We've requested comment from Warner Bros. on what's going on here and whether users' high scores will be uploaded once the leaderboards inevitably get reinstated, but have yet to receive a reply. Chances are Rocksteady's got all hands on deck fixing the game's troubled PC version, which one can hardly blame them for given our Digital Foundry verdict considered it "totally unacceptable."
On the plus side, leaderboards aside, Digital Foundry considered the PS4 version of Arkham Knight a "technical tour de force."
Eurogamer contributor Dan Whitehead was pretty gung-ho about Batman's latest adventure, which he recommended. "The Batman of Arkham Knight is a complex, contradictory figure, a hero with real depth and dimension, and we get to wear the iconic cowl for one last mind-boggling night of mayhem," he wrote in his Arkham Knight review. "Miss out on that? You must be joking."
