I would say unlock Abyss asap and when you put buildings on it , upgrade them to lvl 3 cause they give 5+ mil plunder increase per building at lvl 3(for spy building). I am not HFBC nor HLBC but im going ahead with upgrading Abyss Buildings cause they are giving much better plunder and stats. :lol: Never becoming Abyss BC though :lol:
You got that right. To ug hf spy bldg from 1 to 5 costs 900b and yields an increase of about 642k total. To ug same from 1 to 3 on new lands costs 700b and yields an increase of 870k.Do the easy math...lol
