Tower Cost Specialties

When starting a new game in Bloons TD 4 Expansion, on the "Set Game Mode" screen after selecting a track, you can select a Specialty. There are 7 Specialties to choose from and each one of them lowers the cost of certain things, and raises the cost of everything else. If you usually only use a few types of tower, this could be a great money saving technique.

Here is a list of all the Specialties, as well as what each of them affects:
