Take-Two announced on Tuesday that it had shipped six million copies of BioShock Infinite to retailers by the end of its most recent financial year on March 31.
Infinite was the final title created by series creator Irrational Games, which closed its doors in February. The franchise IP rights are owned by Take-Two, which has yet to reveal plans for the future of BioShock.
September 2012 release Borderlands 2 has now shipped over nine million units and continues to be a "significant contributor" to Take-Two's results thanks in no small part to its robust DLC offering.
Take-Two CEO Strauss Zelnick said this week that he looks forward to expanding the franchise "with new offerings in the coming year", including Borderlands: The Pre-Sequel.
Sid Meier's Civilization V has shipped over five million units to date. The next entry in the franchise, Civilization: Beyond Earth, will launch this autumn.
But the star of Take-Two's business year was Grand Theft Auto 5, which shipped more copies in six months than all of the game's listed above have shipped across their entire lifetimes combined. Rockstar's blockbuster open-world action game has shipped 33 million units on PS3 and Xbox 360.
Zelnick said on Tuesday (via Seeking Alpha): "Looking ahead, we have more than ten unique next-generation title developments including unannounced releases planned for fiscal 2015." These include a new Rockstar game.
