After hearing a movie is in the works, I just feel there is no way they can do it in 2 hours. Just based on the type of book it is, the "chapters" almost would work better as game chapters. Possibly like Heavy Rain where you play different people in different scenarios. What do you think?

 Third person survival horror with a FPS toggle?

Going for a heavy story mode & atmosphere, not so much just spitting out L4D. Sure an online mode would be needed to appease the gaming critics, so tack on TDM/DM and thats as good as any game.

Seems like it would be a great franchise to replace the now confused Resident Evil world. Just good old fashioned zombies and surviving.
