The disaster that is the PC version of Batman: Arkham Knight has gamers angry, publisher Warner Bros. apologetic and halting sales, and developer Rocksteady Studios working hard to fix the issues. But it turns out Rocksteady didn’t handle development of the game on PC. Warner Bros. chose to outsource the project.It has been revealed that the external developer handling the port is Iron Galaxy Studios. This came to light when a forum post by Arkham Community Manager Coda said, “We are working closely with our external PC development partner to make sure these issues get resolved as quickly as possible” in response to complaints.This accounts for why the console versions of the game are free from the same performance issues–they were handled by a different team altogether.Iron Galaxy Studios has been around since 2008, consisting of two studios located in Chicago and Orlando. They mostly work as contractors for larger developers handling ports. Recently they’ve been tasked with developing Borderlands 2 (PS Vita), Destiny (PS3), Killer Instinct Season Two (Xbox One), Borderlands: The Handsome Collection (Xbox One, PS4), and now Arkham Knight. They also handled the PC port of Arkham Origins back in 2013.So it seems likely all the pressure coming from Warner Bros. is being focused on the Iron Galaxy team. Rocksteady may help, but it’s the Iron Galaxy project that needs to be improved to the point of producing a playable game. Regardless of this, though, it still doesn’t explain how Arkham Knight on PC managed to make it through a final testing phase and get greenlit for launch. That fault lies squarely at the publisher’s feet unless they can explain otherwise.
