Potentially three parts, or four--depending on how previous chapters fair, and if I have the funding to continue creating larger scale chapters like Ch. 2! Otherwise I'll have to reevaluate my plan and break things down into smaller chunks to make it sustainable.
Though as it stands, Chapter 3 is going to be broken into two parts so that I'm able to release more content more quickly in the future after the behemoth task of putting out Chapter 2!
