Never mind that BioShock was a game that told its story through broken furniture and level design. Book publishers Tor think you can wring a good novel out of it.
Having already made good game-related money with their Halo series, Tor will later this year be releasing a novel based on BioShock, which will "take you deeper into the realms" of the game's story.
With the sequel already looking a little... off, I'm not sure how much further exposition BioShock's universe can take, but I guess we'll find out when we can actually read the book sometime in "Fall 2009".
