An example of a walkthrough chapter is shown below:
Chapter XX: (Number) Chapter Name
Location: (Name of where it is on the map)
Condition: (Condition for clearing the chapter)
Boss: (Boss Information)
New Units: (If you get new characters, or have the potential to do so, they will be listed here.)
There will be a Tips section, or a General Strategy of sorts. I may add what I did in some cases, and maybe an example of the sort of team I had at the time, though since play styles vary as well as character preference, these are just very general ways to go about winning a level.
