I have already destroyed more than 15 sickle sydicate bases. I haven't got any unit, not even Colossus. Is it a bug or what? I just started attacking bases after kixeye announced the advanced mission only remains 7 days. Appreciate if anyone tell me why. This demotivates me to do any more bases. I am level 25 by the way. Any pre-requsite units before i can claim those special units?
