2K's put a stop on BioShock 2 rumours dragged of its own forums today, saying they're simply wrong.
"Please do not believe everything you read on the internet," said a community manager.
"This rumor circulating is not true. Grab the Game Informer magazine. It's shipped out and should be to subscribers and on store shelves really soon."
Talk - spotted by CVG - emerged earlier apparently taken from GI subs issues, saying a Soviet submarine, co-op and more were involved in the game.
Just goes to show, really.
