Kotaku is reporting that Realtime Worlds, the company behind Crackdown and headed by the man who created the GTA franchise, is currently working on an MMO GTA-style game called ‘ABP’. The rights to the game have recently been bought back from Webzen, a Korean publisher, and the rumor is they plan to build the game and try to sell it to Rockstar so it can be rebranded as GTA: Online. Kotaku’s tip comes from Eurogamer, credited to ‘a credible inside source’.
