Kingdom Rush Frontiers Rising Tides campaign adds 3 new levels each with their own heroic challenge and iron challenge. Greenfins, Redscales, blacksurges, bluegales and CRAB MONSTERS. Come join me to watch some of my high level veteran game play! I'm sure I could have done slightly better on some maps if I played over and over again, but I think most of the strategies will work great for you guys!
