Seven Days to Survive
by Zolton21
Seven Days to Survive turns zombies into a persistent threat: they dig, build and hunt players across the world.
What it does
The mod is a hardcore survival overhaul for vanilla zombies. Zombies gain a much longer detection range, relentless pursuit AI, and the ability to dig and place blocks, so walls and terrain offer only limited protection. Zombies also spawn with randomized armor and swords, and a speed boost. The seventh night, called Oblivion Night, brings the most intense version of this behavior.
Players counter the zombies with the Synaptic Seal, which blocks digging and building within a radius of one chunk by default. Used with right-click, an Echo Shard widens that area to 3x3 chunks, and adding four more shards raises it to a maximum of 5x5 chunks. Sneaking and right-clicking with an empty hand removes shards again. Installation covers the server and each player's game. It is published for Fabric, Forge and NeoForge, with files for 1.20.1 and Architectury API, Fabric API, Forge Config API Port and Geckolib as required dependencies.
Key features
Zombie digging and building
Zombies tunnel through obstacles and place blocks to reach players, so enclosures need more protection.
Synaptic Seal suppression
A special block stops zombies from digging and building in its area, with a default radius of one chunk.
Echo Shard expansion
Right-clicking with an Echo Shard widens suppression to 3x3 chunks, and up to five shards reach 5x5.
Armored, faster zombies
Zombies spawn with randomized armor and swords and receive a speed boost, which makes them more dangerous.
