      • Move away from the mutant zombies and toward the crates.
        • The crates give you either health packs or specialized guns.
    • Shooting the mutant zombies
      • You start off equipped with a pistol.
        • The pistol is the weakest of the available weapons but offers infinite ammo.
        • Use the pistol to fight off individual zombies. This will buy you time to collect air dropped weapons.
      • It usually takes a few shots to kill the mutant zombies.
        • Smaller ones go down in one pistol shot.
        • Most take two shots to take down.
        • Hulking large ones need to be shot three times.
      • You can get air drops of more effective weapons like rifles and grenade launchers.
        • Although these have limited ammo, they are much more powerful.
        • Air-dropped weapons can help you clear large numbers of mutant zombies at once.
        • Use the more powerful weapons to beat back the waves of zombies and the pistol to hold off individual zombies while you retreat awaiting another powerful weapon.
    • Survival
      • You start the session with a full health bar.
      • Each time the zombies attack you, you lose health.
      • Lose all your health and it’s game over.
      • You can replenish your health bar by collecting fallen health packs.
