Zombies are the primary threat of 7 Days to Die and are found all around the world, especially in the game world of Navezgane County, Arizona. A virus known as the Septdiurnal Virus (SDV), also called the Epidiurnal Virus (EDV) a year prior to the nuclear war had transformed human beings into relentless Zombies.
There is little explanation on the causes of the virus, how it spread the world, why it ravaged the world, and no way of stopping it is known to anyone, the virus had ravaged America by the 5th of December in 2033, and a year later in January 15th 2034, nuclear weapons were dropped onto major cities in a desperate bid to wipe out the zombies, leading to the third world war. The nuclear weapons didn’t stop the zombies, and even mutated some.

Zombie Types[]
Normal Zombies[]
Normal zombies are the ones a player usually faces when exploring the world. They can be rather easily defeated with basic weapons but can pose a challenge to new players especially in packs or in close quarters inside buildings.
Note: Zombies have been placed in the Normal List until information regarding their uniqueness comes to light. Uniqueness is defined by the difference in damage that they can do, or a special feature/attack. A full List of Zombies is available. Most zombies have the possibility of having a version of themselves that is either Feral or Radiated.

- Plagued Nurse
- Putrid Girl
- Rotting Carcass
- Reanimated Corpse

Tough Zombies[]
Tough Zombies have more health, resistance and damage, making them harder to be dealt with.
- Bloated Walker
- Fat Hawaiian

Special Infected
Most zombies differ only in appearance, however some zombies have special features and abilities:
- Burn Victim can set the player on fire if contact is made or if it attacks the player. This zombie spawns commonly around the burnt forest biome and can also be spawned in for 'Clear the Area' tasks from the Trader.
- Crawler Zombie is one of the earliest special infected encountered within the game, and unlike most zombies, it will always crawl along the ground and may use this to its advantage to ambush unsuspecting players or reach low gaps. It is also immune to being stunned.
- Demolisher is a physically resistant zombie that can easily break spikes and hit hard. It spawns in the later Blood Moon hordes and can be blown up by shooting the C4, which is strapped onto his torso. It also has a small chance of spawning in the downtown area of cities, with a slightly higher chance to spawn in cities in the Wasteland compared to the other biomes.
- Feral Wight is a very tough zombie. It requires lots of strength to kill and is not affected by sunlight due to only spawning as a feral, regardless of the world's settings. This type of zombie will only spawn in cities, Blood Moon hordes, caves, or via screamers during later days. When killed they give the highest amount of experience points and carry the best loot of all zombies.
- Mutated Zombie is a zombie with a ranged spitting attack somewhat similar to the Infected Police Officer. However the Mutated Zombie's ranged attack does significantly less damage to blocks. This zombie has a chance to spawn anywhere in the Wasteland. If stepped on or being hit directly, the acid produced by his spitting attack will give the deadly radiation status effect.
- Infected Police Officer has a high amount of HP similar to 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 acidic vomit towards them, which can destroy blocks and instantly kill unarmored players. When at low health, it will attempt to sprint towards the player and will explode once close enough, usually killing the player instantly unless it's killed before it reaches them. An Infected Police Officer tends to drop good loot, but if it has killed itself by exploding, no loot bag will spawn.
- Screamer Zombies are the advanced scouts of the undead. When you produce a certain amount of "heat", a Screamer or two will spawn to investigate. If they detect you, they will scream and a horde will spawn. Kill them quickly to avoid the hordes. Your heat map rises when you perform various activities, campfires and forges may raise it, as can cutting trees, mining, using certain weapons, explosives, the Augur or even crafting. The heat level drops if activity in the area ceases.
- Spider Zombies, as their name implies, are able to jump at the player, if they are relatively close and while they are only on four, their attacking affects only the lower part, so sometimes that may result in sprained or broken leg. They can also stun the player. They could at the past climb the walls and spit the webs, but fortunately, Fun Pimps removed it from the game
Animal Zombies[]
Zombie animals exist in the world along with the traditional human zombies. Killing and harvesting them is one of the ways to get rotting flesh which is important for farming.
- Zombie Bears have more HP and are stronger than regular Bears. They are covered in blood and will attack anything on sight. In later days, Screamers can call them.
- Zombie Dogs are faster than other zombies and are not affected by sunlight, making them a dangerous predator at all times. They typically spawn in packs, and can thus maul a survivor into shreds. Sometimes they may spawn as wolves.
- Zombie Vultures fly around and attack the player from above, and will attempt to make range after it successfully attacked the player to avoid retaliation. They spawn in every biome and can be avoided by hiding in a shelter, though their ability to break blocks might leave you a limited amount of time until they break a hole in your roof.
Removed Zombies[]
See Removed Zombies for more details.
How to defeat[]
Generally a well-placed headshot with a sledgehammer will one-shot a zombie, sometimes two. If their head blows off, it’s an instant kill.
With feral and irradiated zombies, it is best to keep your distance. Using a firearm is your best chance to defeat one of these types. It is recommended that you get the Rad Remover Mod to help against the irradiated zombies.
Behavior[]
Day[]
Zombies move slowly during the day and will not chase after the player if they stay far enough away. Zombies will mostly stay idle around their position but when they spot a player they will move in a straight line towards them, destroying any blocks in their way. This behavior can be changed while creating and entering a world with the setting "Zombie Day Speed".
Night[]
At night, zombies start running and begin to wander around. They will attempt to detect survivors at night, using proximity, sight and light. Zombies will try to occupy the space directly above or below the players' location. During the 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.
Zombies react to pain in certain areas. For example, if hit in the leg, they will hold their leg and be stunned for a couple of seconds. If hit in the torso, the zombie may be stunned, causing them to fall to the ground. Note that this does not kill them, and they will get up a few seconds later and resume their assault. A player should never assume the zombie is dead simply because it is on the ground, instead keep in mind that an EXP gain will be shown in the lower right corner of the screen when a zombie is killed, which is essentially a notification system that tells you if a zombie is down or will get back up.
Zombies can and will climb ladders. If a player and a zombie are on a ladder and a player is below the zombie, with the zombie having no movement options besides going up and down the ladder, the zombie will be unable to attack the player. It is unknown if this is intentional or not.
Combat[]
With the exception of the Mutated Zombie and Infected Police Officer, all zombies have a single style of attack, which is a melee swipe, slash or punch (However, if both of a zombie's arms are taken off, they seem to bite the player instead). All attacks have a chance of causing an Infection, Stunned, Fatigue, Sprained Legs and Arms, Lacerations, and/or the Bleeding debuff, the latter being more prevalent when fighting against Zombie Dogs. Melee combat against zombies is relatively simple - aim for the head and walk in and out between strikes. Every hit has also a chance to dismember a limb from zombie. Dismembering the head will kill any zombie instantly, so using a weapon under the attribute the player focuses on is advisable. However, against a horde, melee combat can lead the player to be surrounded by zombies which is extremely dangerous, especially at night. This should be avoided at all costs as a single stun, bleed, or infection will most likely be fatal. Against hordes or when safety is of the ultimate priority, guns are the safest in this regard, but they heavily rely on ammunition. The Primitive Bow is an excellent choice for fighting zombies as both it and Stone Arrows are easy and inexpensive to craft, and using the bow makes little to no noise, thus attracting less attention from nearby zombies.
The Stealth System can be used to avoid zombies. Stealth mode is activated when crouching (default 'C' key, or toggled on/off by 'left-Ctrl' key). You will make less noise while moving and searching in stealth mode, but movement while crouched is slower than while walking. Crossbows and Bows can be used for stealth kills without drawing much attention from other zombies, and both get double damage from stealth shooting. Attacking stunned zombies will give a stun bonus of 3 times the normal damage, making it easy to finish them off. Some objects, such as Small Stones and Snowballs can be thrown to create a distraction or to lure zombies to other areas.
Defenses[]
Generally, a base is never perfectly safe from zombies. Repairs are a normal duty; fixing blocks, replacing traps, etc. Even the most fortified bases can fail when under siege by wave after wave of zombies, particularly during the Blood Moon Hordes. The following tips can help extend the longevity of a base:
- Use traps, like Wood Spikes. Other forms of traps include land mines or pitfalls, but require extensive pre-building or restocking.
- Zombies won't notice hatches or wooden poles, this is very useful for long pits to harm zombies with a clever death trap.
- Build walls at least two blocks higher than the zombies can jump (usually three blocks high) to prevent them from breaking an upper block on a two-high wall and jumping over it. Keep in mind, however, that zombies can jump on top of each other like blocks to climb slightly higher than they can jump.
- 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 does 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 Claw Hammer, Nailgun and Stone Axe can all repair broken or damaged blocks. Most blocks can be upgraded to be more durable.
- Allow visual sight of your entrance from inside your base. This is most commonly achieved by having a balcony or roof access, so as to make it possible for a player to shoot at zombies while remaining more or less safe.
- Have a way to attack the zombies through your defenses where they can't attack you. Whether by Wood Spikes, a high wall with a direct line of sight or Iron Bars inset into the walls, you need a way to clear out large numbers of zombies safely.
- 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. If building near water, the banks of the water body will cause problems for the ditch. 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 should 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 overrun. 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, medicines, and weapons are recommended. Park a vehicle, such as a Bicycle, Minibike, Motorcycle, or 4x4 Truck a short distance away from your base for a quick escape.
- Another much more effective Escape Route is the Tower Escape. If you have a high building or tower, and you are able to jump over your tower's outer walls, you can make an elevated building just outside your wall line with Hay Bales on top. Hay Bales reduce fall damage, so if Zombies breach your defenses and climb up your tower to attack, you can escape by getting onto the top floor and jumping onto your hay bale escape route just outside of the wall, running, recouping, and making a counterattack to take back your base.
- Underground bases 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, though keep in mind that Zombies can dig down.
- Zombies usually prioritise doors and windows over walls, so reinforcing walls next to doors with cobblestone and cement, building iron or steel doors and putting more traps where doors and windows are will slow down or kill a great deal of zombies.
Zombies have no regard for their own safety and will attempt to charge even through Wood Spikes or other traps, even if it means certain death. However, as swarms of zombies die and defenses slowly degrade, it will be easier for them to clear a path to the player.
Fall damage for any zombie at any height will only reduce its health by half and will stun the zombie, making it vulnerable to triple-damage while stunned.
