Defend your base in this survival shooting game, Zone Defender! You need to survive after three minutes of shooting all those creatures. Do not let them inside the red perimeter or else it will deduct your current defense gauge. You need to be fast in eliminating the monsters because once they got in your base it will be hard for you to keep up the pace!
Lock and load now and start shooting, see if you can even survive the longest three minutes of your life!
