Zombies are the primary threats of 7 Days to Die and are currently found all around the world, especially in the game world of Navezgane County, Arizona. An unknown virus is transforming human beings into blood-thirsty zombies. Nobody knows how, nobody knows why and nobody knows how to stop it. Now most of the population have turned into these monsters.

Most zombies are the same, except for the following zombies that have special features:
- The Bloated Walker is more resistant and does more damage. They also have a larger loot list filled with better items (ammo, weapons, etc).
- The Spider Zombie can climb vertically on blocks of any height, they can even climb trees. These zombies are also known as "Scouts", this is because they are attracted to noise and heat and since alpha 10 they only spawn according to the Heat Map. If the player makes too much noise/heat a group of 3-4 Scouts will spawn and if they spot the player they will screech and call a horde to the player's location.
- The Zombie Dog is faster than other zombies and is not affected by sunlight, making it a dangerous predator at all times. They typically spawn in packs, and can thus maul a single survivor into shreds. This is by far one of the most dangerous zombies as of now.
- The Burn Victim can set the player on fire if contact is made.
- The Infected Police Officer has high amounts of vitality like the Bloated Walker, but also possesses a deadly ranged attack. Once it spots a player from a decent range, it will release a stream of acid towards him/her, which can destroy blocks and instantly kill unarmored players. When damaged but not killed instantly, it will attempt to sprint towards the player in a feral rage, and will cause a self-inflicted explosion once close to the player or when killed. An Infected Police Officer tends to have good loot, but if it has killed itself by exploding, no bodies will be available for looting.
- The Feral Zombie is the strongest one out of all zombies. It takes several headshots from a flawless quality 44 Magnum to kill. These zombies will only spawn in cities at night or in caves and once killed they give the most amount of xp points. They also have the best loot of them all, carrying exclusively gun parts.
- Feral Walker removed in Alpha 2
Zombies move slowly and are easier to kill during the day. However, once night comes, they start running. Once a zombie senses or begins hunting a player, they will generally move in a straight line towards their prey, destroying any blocks in their way. Feral Zombies, Infected Police Officers, Plagued Nurses, and Bloated Walkers drop the best loot, although the rest of the zombies all have a chance to drop any Recipe Book.
With the exception of the Infected Police Officer, all zombies have a single style of attack, which is a melee swipe, slash or punch. All attacks have a chance of causing an Infection, Stunned or Bleeding debuff, the latter being more prevalent when fighting against Zombie Dogs. Melee combat against zombies can be simple - aim for the head and walk in and out between strikes. However, against a horde, this can lead the player to being surrounded which can be extremely dangerous, especially at night. Against hordes or when safety is of the ultimate priority, projectile weapons are the safest in this regard, but they heavily rely on ammo and other resources.
Headshots, with all weapons, inflict the most damage to zombies. On lower difficulties, a single blow to the head using a good quality Stone Axe can take down all normal zombies, not including the effects of fatigue or weapon condition. A headshot from a Hunting Rifle or a Crossbow kills most everything, especially with the x2 sneak attack damage bonus.
The Stealth action can be used to avoid zombies. Crouching ('Ctrl') makes less noise while moving and searching, but moves slower than walking. Zombies will detect a player if in their line of sight or external factors have drawn their attention (e.g. using tools, looting containers, carrying food with an odor, etc.). Using Sneak while scavenging has a greater chance of going undetected. The Crossbow can be used for stealth kills without drawing much attention from other zombies. Throw objects like Small Stones and Empty Cans can be used to create noise as a distraction or to lure zombies to other areas.
Zombies in the day will not chase after you if the player stays far enough away, and will mostly stay idle around their position. At night time zombies will wander and attempt to sense you through sight, smell, or proximity (see notes). At night, zombies appear to be more active the closer a player is to them. For example, if a player stands directly on top of a wall, no matter the material, the zombies will destroy the blocks in the wall very rapidly. However by contrast, if the player is standing in the middle of a room, and is 15 or more spaces from all the walls, zombies will not congregate in one spot to destroy the wall and it will take them much longer. This being considered, larger bases are usually more effective than smaller ones.
Generally, a base is never perfectly safe from zombies. Repairs are a normal duty; fixing blocks, replacing traps, clearing gore blocks, etc. Even the most fortified base can fail when under siege by wave after wave of zombies, particularly during the 7-Day hordes. The following tips can help extend the longevity of a base:
- Use traps. For static traps, there are only two options: Wood Spikes or Wood Log Spikes. The former does more damage but breaks down faster, while the latter does less damage but will not be damaged unless directly hit (In newer version such as A12, Wood Log Spikes breaks down when it does damage) . Other forms of traps include land mines or pitfalls, but requires extensive pre-building or restocking.
- Build walls at least two block higher than the zombies can jump (usually three block high) to prevent them from breaking an upper block on a two-high wall and jumping over it. Also, with the inclusion of gore blocks, adding an overhang to a wall will hinder zombies forming a 'ramp' of their dead. (Wood Log Spikes underneath an overhang is a particularly strong defense design).
- Build double layer walls to rely on more than one layer of defenses should a zombie siege occur. This is especially true if the player wishes to fortify their base, but do not want to break down their original layer of walls.
- Make frequent repairs. It is wise for a player to always check for damages whenever possible, especially after a siege. The Repair Tool comes in handy for this. Also, certain blocks can be upgraded to have more durability (Cobblestone walls, Doors, etc.)
- Allow visual sight of your entrance from inside your base. This is most commonly achieved by having a 'balcony' or a roof access, so as to make it possible for a player to shoot at zombies while remaining more or less safe.
- Make a way to attack the zombies through your defenses where they can't attack you. Whether by Wood Spikes or Wood Log Spikes, a high wall with a direct line of sight down, or iron bars inset into the walls, you need a way to clear out large numbers of zombies safely. They will always find a way into your base otherwise.
- Moats and ditches. These take time and planning to build and as such should only be attempted once a base has other defenses. Combined with spike traps these are very effective defenses, though hinder attempts to farm food or any escape routes. Also if building near water the banks of the water body will cause problems for the ditch. Note: having a moat or ditch requires strong defenses at the "bridge" of your moat since this is the easiest access point.
- Escape routes. A base can have an easy access escape route that zombies or other players cannot enter. One suggestion would be to build a tunnel out of the base and then block up the entrance with one layer of dirt, thus making it inaccessible to zombies or enemy players whilst allowing for easy escape should your defense become over run. An escape kit can be maintained near the exit to the passage so that it is possible to survive until your base can be reoccupied food, water, and medicines are recommended. As of patch 12 the minibike could be placed here as well for easy escape.
- Underground bases. They can take quite a long time to make and require the player to have pre-existing resources, but are extremely easy to fortify and defend in both PvP and PvE.
Zombies also have no regards for their own safety and will attempt to charge even through wooden spikes or other traps even if it means certain death. However as swarms of zombies die, defenses slowly degrade and eventually zombies will clear the path to player character attempting to overrun opponents.
- The sounds zombies make when wandering around sounds like they are grinding their teeth.
- Zombies will attempt to detect player's location at night time using proximity, smell, sight and light. They will try to occupy the space directly above (or below) the players location. If the 'Feral' difficulty is enabled, zombies will be this aggressive at both day and night, and can also detect a Survivor through walls at night.
- The Zombie Dogs and Crawler Zombies can fit through 1x1 holes (one block size) while other zombies fit through a 1x2 hole (two blocks high, 1 block wide).
- Zombies currently do not register that there is a Storage Chest in front of them. Whether this is a bug or intentional is unknown, but it is a great way protect yourself from any Zombie threat when used as a wall.
