7 Days To Die is an open-world survival game where you can gather resources, build bases and fight hostile creatures, including zombies. These undead creatures are easy to find in the environment, but you can also use the creator mode to spawn as many zombies as you want on your location, here's how.
How to Spawn Zombies and Items in 7 Days to Die!! (Alpha 19 – Creative Menu & Debug Menu Guide)
Spawning zombies or other creatures in 7 Days To Die can be easily done by enabling the in-game debug menu without using any mods. To do this, press F1 on your keyboard to open the console menu. Type dm, press enter and you will get a confirmation that says debugmenu on. You can then close the console by pressing F1.
Now press F6 to open the Entity Spawner menu. In this tab you will get a list of all the animals and zombies (see image above) that you can spawn in the world. Simply click on the type of zombie you want to spawn and it will appear in front of you. To spawn multiple zombies, click on the name the number of times you want to spawn.
As you can see in the image above, I spawned a zombie and it attacked me; so be careful, because creatures that are hostile to you will attack you as soon as they see you, whether it is a zombie or a predator. The spawned creature will appear exactly where your sights are, so make sure to place it a bit further away so that they don’t attack you right away.
