“Good TD game for casual playing here and there, took 25 hours to beat on all difficulty and to get all tech points. A good game to pickup on sale and play when the internets out or no ones online to play with in other games.”

— a player, Steam review · 7 hrs played“I enjoyed the previous game. This one feels ordinary and not exciting. What was fun about tactics before is not possible in this game.”
