2K's BioShock sequel is off to a good start. Take-Two Interactive announced today that the 2K Marin-developed BioShock 2 has surpassed 3 million in sales since its release on the Xbox 360, PC and PlayStation 3. Good job, Mr. Bubbles.
That's a positive step in the BioShock 3 direction, with BioShock 2 quickly catching up to the original game's 4 million lifetime to date sales.
Take-Two also had some sales bragging to do about its biggest cash cow, the Grand Theft Auto series. The publisher has pegged sales of the latest installment, Rockstar Games' Grand Theft Auto IV, at 15 million units sold worldwide.
Finally, in other million-selling sales news, Take-Two puts sales of Carnival Games at more than 6 million on the Wii and Nintendo DS. It's continuing to sell so well, Take-Two execs say, that there's no need (yet) for a sequel.
