When most of Irrational Games was laid off earlier this year many assumed it was the last we'd see of BioShock, at least until 2K Games mustered the courage to have one developed by a secondary studio ala BioShock 2. Nonetheless, it would appear something BioShock related is about to happen, because 2K Games posted this teaser image (above) on its official Twitter account earlier today, along with the text: "Oooo, what COULD this mean?!".
What's a scantily clad woman with an apple got to do with BioShock? Well, in dark lettering at the bottom of that image is a reference to Poseidon Plaza, which is a prominent location in the original BioShock. The reference seems to indicate that we might see a repackaging of the original game in the not-too-distant future. Whether that repackaging is relevant to PC owners is another question.
After all, it's unlikely the teaser is related to a brand new BioShock game. BioShock Infinite only released last year and if there was a fourth BioShock game, surely it wouldn't return to Rapture? Surely ? In the meantime all we can do is speculate.
