I was actually planning a zombies/Bioshock story a few weeks ago, where the guys get transported to Rapture after Ascension. Alas, although I love Bioshock, I haven't been able to play it in months, and have forgotten the layout of Rapture. If you could help me out, maybe, then I'd definitely continue work on it. It was gonna have zombies and Splicers, and the zombies would be there because ADAM, in this, would be another form of 115, so when the Splicers die, the 115/ADAM in their body turns them into zombies. And then, we could have zombies using Incinerate! or Telekinesis. Either way, it was just an idea.
