Difficulty
Every region has 6 difficulty levels available: Easy, Medium, Hard, Insane, Nightmare, and Impossible. Difficulty levels are unlocked by reaching wave 100 on the previous difficulty. Each difficulty is given a multiplier which increases the enemies attack and defence.
While each region usually only spawns a specific selection of enemy elements, on Impossible difficulty all elements are spawned.
