Ensuring your underground base remains secure in 7 Days to Die involves disabling zombie digging in sandbox settings and strategically designing subterranean shelters.
Advantages of Underground Bases
Underground bases in 7 Days to Die provide enhanced safety and flexibility. Zombies cannot dig when the digging mechanic is disabled via sandbox settings, allowing hidden, long-term survival shelters. These underground havens are perfect for secure storage, crafting, and refuge during horde nights while significantly reducing the risk of zombie intrusion.
Hideout Planning in 7 Days to Die
