Hi! Where do I find the endless mode. I ve got a premium account and finished the game including the achievements... still the endless mode is nowhere to find...??? Can anyone hellp me get this? THNX!
Welcome to the forums, Alegria! Though I do have some potentially disheartening news which is that one can only play endless mode if one if using a mobile device to play KR. No worries if you're a mobile user though, since Kingdom Rush (the first one) can be downloaded for free on mobile.
Mentioning that you have a Premium account leads to me to assume you are on Browser - playing either on flash or Armor Games, and as Ninja said regrettably Endless Levels are unavailable anywhere but on mobile versions of the game.
