• Aim for the head! Headshots deal an extra 15% damage. This can mean the difference between 2 shots vs 3 shots for some weapons.
  
• Work on prioritising zombies based on their threat. Start with the zombies attacking your barricade, then the zombies likely to reach it soonest, and finally the zombies furthest away.

• You will start to unlock Explosive Barrels from Level 2, and Grenades from Level 3.
  
• Both deal massive damage but are found in limited quantities. You should only use or explode them when you would die otherwise, or when there is a big clump of zombies that can be taken out.
  
• If you allocate a Barrel during a night but don't shoot or explode it, it will be returned to your inventory.

• Police Zombies and Military Zombies. both with Armor, will start to appear from the middle of the game.
  
• Police zombies have 25% damage reduction when hit in the torso, and Military zombies have a 75% reduction when hit in the torso.
  
• Their head areas are unprotected, so you should aim for their heads carefully.
  
• Survivors will not automatically target head areas, so you should target armored zombies as a priority when they appear.
  
• Armored zombies cannot run, except in NewGame+ mode.

• Survivors will shoot infrequently, and with limited accuracy. They also deal reduced damage compared to the player.
  
• Based on that, you should equip them with high-damage weapons as a priority, such as rifles, shotguns, and heavy pistols. You should give these weapons to your Survivors ahead of yourself.
  
• When Survivors are equipped with automatic weapons, they will fire them in 3-round bursts.
  
• When the barricade is destroyed, survivors will run away and not come back. However, it is easier to find Survivors from Looting when you have a low number of them.
  
• If you lose a Survivor, you do not lose their weapon.
