What if all towers and enemies were initially the same, and you were presented with only one choice per wave? What if this choice affected not only towers, but your enemies too?
The choices are randomly generated. Your decisions will control the progression of the game: fast but weak enemies, massive but resistant ones, ones with dodge, flying or otherwise - make your choice!
How will you advance your towers to counter the enemies you build up? What combinations can you muster to progress deeper into the chaos?
