On his personal Twitter page, Levine wrote, "I wrote my tiny corner of the BioShock novel last night. Hard to describe the feeling of writing for Ryan again after 3 years." He's referring to Andrew Ryan, the creator of the underwater city of Rapture at the heart of the first two games in the BioShock series. When asked by another person if it was hard to write the character again Levine replied with, "It wasn't difficult, but I had to say something about him that I hadn't said already. I think I found a tiny, tiny new corner."
As we have reported before the BioShock prose novel was first announced back in 2009. John Shirley wrote the bulk of the novel and it's currently scheduled to be released via Tor Books in July.
