MineWarfire Land Defense is a defense-style shooter in which your goal is to protect your area from zombies who are trying to take over the world.
You can move your soldier up and down by pressing W and S, and you can shoot by clicking. Every time a wave of zombies comes at you, you have to shoot them down, but be careful not to get shot by them instead, since losing means your health bar is empty.
As you kill enemies, you get points that you can use to buy more firepower, shields, and other power-ups that will help you beat each new wave of enemies, no matter how strong they are.
Have fun and good luck!
