Squad Defense

Go with the army to the streets where the struggle for the survival of the human race is raging. Mutated monsters are attacking people and turning them into mindless walking zombies devouring brains. You, as chief commander and strategist, have to place units in a defensive formation, and at no cost let the enemy go through. In the beginning your resources are limited and you will only have to use shooters. But over time, when you form your unit, defenders and heavy armored soldiers will come. On the other hand, the enemy grows stronger over time and mutates into stronger forms. Try to win this fight and save the world. Have fun.
