Earlier this month Batman Arkham Knight launched on the PC and just one day later, was taken off of store shelves due to the issues and massive backlash the game faced for having a sub-par PC port.
Now Warner Bros, the small team at Iron Galaxy and a few of Rocksteady’s own engineers are taking the PC version back to the drawing board and making sure it actually meets standards before going back up on sale. Unfortunately, all of that takes time, so we won’t be seeing the game back up on Steam until the Fall, and that’s at the earliest, it is possible that the game may take even longer to fix.
Now not everyone claims to have had such an awful experience with the game on the PC (although I think a few of them are lying to themselves), but due to the amount of attention the re-release of the PC version needs, all DLC has been delayed for the platform.
In the announcement post from Warner Bros, the publisher took the time to once again, apologize for the mess it has created: “Again, we would like to apologize to you, the fans, and let you know that we are taking full responsibility for releasing a product that did not meet our quality standards, which is why we suspended sales of the game as soon as we understood the issues.”
Also consider saving up upgrade points to give your disruptor a 4th charge.
