I was checking out this website called gamespersecond.com and came across this BioShock Infinite spoiler. It pretty much explains how all the things in the game break down and how it ends. It was a pretty good article and I would recommend giving it a look. This article has spoilers so if you do not wish to know how the game ends, I would not recommend reading it. If you could care less, go ahead and click here for the story.
