When I first started playing Tankie Online I really never concerned myself with becoming a Generalissimo. I just played for free to kill the time. Well, I finally made Generalissimo a couple of days ago, and after all this time I never spent any real cash, and have amassed a considerable amount of crystals and an unbelievable amount of supplies. I seldom ever used supplies and just played the game for fun. I have been using M3 Wasp and Rail Gun. So for those wanting to become a Generalissimo without going into debt, it is possible. Yes, it takes longer, but each level brings new challenges and more fun. The key, never give up.
