Better late than never, I suppose. According to a retail listing on Amazon France and European retailer Game Mania, a PC port of Injustice 2 may be coming in the near future. NetherRealm Studios and Warner Bros. Interactive haven’t had the greatest history with PC ports, with the PC version of Mortal Kombat X being nigh-on unplayable when it launched. It was eventually overhauled when MKX received its grand netcode upgrade, but it was too-little-too-late for many PC fighting game fans.
Based on the Amazon France page listing the Deluxe edition of Injustice 2, NetherRealm looks to be releasing the PC version with all the DLC included — similar to Mortal Kombat XL. If this does turn out to be legitimate, I hope NetherRealm have passed the port onto a company that won’t release a buggy mess of a game.
Neither listing hints at a release date, but my guess would be that a potential PC port would launch alongside Fighter Pack 3 later this year or in early 2018.
