I cannot seem to access any units other than the basic Tech 1 units. I have tried upgrading to tech 2 and tech 3, but no other unit options appear. Help!
lol not sure what you mean... If you upgrade to level 2 and 3.... more buildings are available automatically and new units are available in the buildings...
Maybe you think you are tiering but you aren't.. are you sure you press the upgrade on the HQ.. the one thats 3500 is tier 2 and the 10000 one is tier 3
Could you please tell me what did or changed? I can add this info to my FAQ in case another user has the same issue.
