Zombie

Zombies are above-ground enemies that appear at night, and are a primary reasons newer players will want to build a shelter quickly to remain within indoors at night. They are generally among the first enemies the player will encounter, as they appear nightly along with the Demon Eye in areas where players first spawn. Multiple NPCs living in the area will reduce or prevent local enemy spawns, including Zombies and other nightly enemies, though NPCs are only available later in the game.

Zombies walk towards the player in order to make contact, which is their only method of attack. They can jump and navigate Platforms. They will kick closed Doors in their path repeatedly, but will only successfully open them during a Blood Moon event.

Tips

 * While they may move slowly, they are surprisingly good jumpers. They also have a fair amount of health and cause significant damage to newer players. It is advisable that new players remain indoors at night until they gain better Weapons and Defenses.
 * The Swamp Zombie is the fastest zombie AND also pretty knockback resistant to new players.
 * A simple Wooden Sword swung repeatedly is enough to keep one or two zombies at bay. Three or more Zombies will likely be able to get past the sword and cause damage. Weapons that can hit multiple enemies work best. The Spear or Vilethorn are ideal for this job. Ranged weapons also work well, like the Bow; Shuriken and Throwing Knives are ranged weapons that also pierce through multiple enemies, making them good candidates as well.

Blood Moon

 * If one wishes to avoid Zombies entirely during a Blood Moon, blockading doorways with any Block type will stop Zombies from entering your home. Placing a Wood Platform, Wooden Beam, or other piece of Furniture next to the door on the inside will prevent doors from swinging inward, which is the only way Zombies can enter.
 * Placing Doors above the ground level, or digging a trench that is the height and width of 2 blocks, forces Zombies to jump at the door, during which they can't open your door.

Trivia

 * The Spore and Mushroom zombie may be a reference to the game The Last of Us where a fungal disease turns humans into fungi-covered zombies.
 * The Spore Zombies could possibly be a reference to The Last of Us, in which zombie-like infected humans are created through a mutated fungus known as cordyceps, and those that have aged significantly have grown mushrooms on their heads.
