Castle Wars 2 is a superb turn based tactical card game with unlockable cards and multi-player mode. Also it's an highly addictive game where your goal is to crush your enemy's castle or be the first to build a 100 storey castle. Crush or be crushed!
Basically there are three types of cards: Attack, Defense and Resource upgrading & stealing. So, first you should classify all of the cards and make your own tactics by using the right card at right place. For example your strategy may be based on stay in defense, stealing resources from the opponent castle and keep it down while you are upgrading yours in this way. If you succeed to get your castle reaching its maximum before the opponent's castle, you win. Or you can perform an offensive tactic based on using mostly the attacking cards. It's up to you!
