Big Tree Defense 2: Evolution is an innovative defense game in which you grow and defend trees. Defend each tree from waves of harmful bugs by growing its trunk, adding new branches, sprouting flowers and creating weapons. Tree growth and weapon creation requires water, which is collected by the tree's leaves. Mature weapons will turn into fruit, and you can collect the fruit by clicking on them. Unlock new weapons with your collected fruit, and trade your leftover fruit for water before each battle.
