Remember when Batman: Arkham Knight [official site] was released? Yeah, the memory’s a bit hazy to me too. Warner Bros. pulled the game from sale two months ago due to its shoddy performance, and still have no clear idea when it might relaunch – though it seems it’ll be longer than expected (and planned).
Warner Bros. had planned to release an “interim” patch in August to improve performance for folks who managed to buy the game before it was yanked, but their latest community update makes that seem unlikely. That patch only entered testing last week, with WB saying they hope to launch it “in the next few weeks”.
