Survive the night fighting off zombies from your barricade. Survive longer than a day by making use of the daylight hours effectively by repairing your barricade, searching for weapons and looking for other survivors to help repair and defend.
You are sent out into the desert on a diversion mission. You must survive enemy attack for six days until main forces will take over. Defend your desert position for six long days.
Snipe the snipers before they snipe you. Once you start shooting, the sniper timer will count down fast so you may want to try and remember their positions if you can. Watch out for the sneaky soldiers that move in and out of cover.
Zombies have attacked and mankind has been devastated. Every day is a battle in the war to survive. Few remain to hold them off. Shoot those zombies and save the world.
