Les mécaniques du jeu sont simples. Le jour, il est préférable de sortir afin de collecter des ressources, d'explorer ou encore de migrer vers de nouvelles contrées, villes ou villages. La nuit, il est conseillé de se trouver dans un abri ou une maison fortifiée, afin d'éviter d'être tué par les Zombies, plus puissants et rapides de nuit.


Housing is vital to survival and can be easily destroyed by zombies. You can add protection to buildings by adding traps and using stronger blocks (cobblestone instead of wood). For example, if you create a perimeter of Wood Spikes around your house, zombies will ignore the spikes and will run straight into them, therefore losing health and sometimes dying and also damaging the wood spikes a little bit. Also, if a house/shelter/base is being built, it must be made sure that supports have been built to hold up the roof, or else it will most likely fall if zombies break some blocks, and therefore kill you. This is the main problems with zombies during the night time, because they'll just attack your shelter (they'll attack more if they know where you are, so when you go back to your base/home you should always make sure to lose/not get zombies attention). If a group of zombies (over time) destroyed the first layer of your house all the way around it... your house would collapse.

  • Note: Walking from one end of your shelter to the other seems to confuse the zombies, making them less likely to cause significant damage to your shelter.

There are many types of generated structures throughout the map, however these structures can be easily destroyed by Zombies as it is made from various types of wood. The best places to house are on top of: 3 to 4 floored buildings , gas stations/scrap yards, farm houses & barns. It is preferable, around the later stages of the game, to build your own house Underground at Bedrock or to build a fortified castle ( Reinforced Concrete )in a valley with traps and obstacles round your fort while having your storage underground.

  • Note: If having an underground house, keep moving your house 7-10 days so the Zombies can never get to you while digging ,as Stone is quite tough to break with bare hands & to go more than 40 blocks deep makes it more than ever to be safe in.



Daytime is between 6:00 AM to 24:00 AM on default settings. During daytime, it is recommended that players spend most of their time strengthening a shelter and finding loot such as Weapons and Food. Zombies move at half the speed of an average walking player.


Night is between 21:00 PM to 6:45 AM. When night begins to fall, zombies become more dangerous and will try to find the player, so it's advised to watch the time and take shelter before night falls. Zombies at night are more active and aggressive. They deal more damage and come in waves. If you kill all the zombies, a new wave will appear. Zombies become very smart and will try to reach you during the night, even if that means breaking blocks. Zombies can even spawn in your house if you're not around, this can be prevented by placing a Sleeping Bag down which will stop Zombies spawning within a 15 block square. Zombies move twice the speed of an average walking player, so if you have no Weapons &/or Painkillers you will probably die.


Since the A11 release Zombies are running based on sunAngle rather than the Day/Night time. Zombies can start running around 18:30 or even sooner, so it is recommended to stay near your home or another secure location after 17:30 unless the survivor is well equipped with Stamina regenerating items (Coffee, Beer, Grain Alcohol, or Honey) and well armed/armored.

Heat Map

Some actions will generate "Heat" in the players area. Every chunk (~50*50 m^2) has a heat level. Over time the heat level decreases. But if the level is high enough some Spider Zombie will investigate. If they find the player, a horde will spawn in. After this the heat level will decrease.

Actions that increase the heat level:

  • Explosions
  • Weapon fire noise
  • Cooking
  • Smelting
  • Chopping trees
  • Mining
  • Building huge structures

Quality System & Leveled Crafting

As of Alpha 11, 7DTD now features a quality system related to almost all gear and weapons, both crafted and looted.

Item Quality Levels

The Quality system has 6 levels:

 Faulty - 1-99 (Gray durability bar)
 Poor - 100-199 (Orange durability bar)
 Good - 200-299 (Yellow durability bar)
 Fine - 300-399 (Green durability bar)
 Great - 400-499 (Blue durability bar)
 Flawless - 500-600 (Magenta durability bar)
  • Note: All weapon/armor stats are calculated based off Item Quality, so a found Flawless Wooden Club could do more damage than your crafted Faulty or Poor Spiked Club.

Gun Quality

Gun Parts follow the same quality system, but average the gun quality across all parts. A pistol with 2 Flawless pieces of 600 Quality each and 2 Fine pieces of 300 Quality each will make a Pistol with a quality of 450. After implementing this in Alpha 11, Players can take all the parts from a disassembled gun as opposed to previously only being allowed to take one piece of the gun when disassembling and losing the other pieces, and easily replace a lower quality piece with a higher one once acquired. It is not uncommon to find a Faulty gun with one or 2 pieces of Great/Flawless parts, so it is advised to always check by disassembling the gun in the crafting grid output box before outright scrapping/discarding the gun.

Leveled Crafting

Crafted armor and weapon quality is now based on level. The current system takes the player's level and multiplies it by 10, then adds or subtracts up to 50 from that number: (Level*10) [+/-] (<= 50) = Item Quality

As example a player who is level 17 can craft items with a quality rating as low as 120 or as high as 220, although it rarely works out to a perfect 50 one way or the other, with random numbers such as 143 or 201 being crafted at that level.

The following items are not included in the quality system, crafted or looted:

  • Clothing (Pants, Shirts, Jackets, Mining Helmet, etc.) (since A12 it is)
  • Iron Gardening Hoe
  • Bow & Crossbow (since A12 it is)
  • Bone Shiv (since A12 it is)
  • Repair Tool/Claw Hammer
  • Nailgun/Chainsaw/Auger
