About this Mod
This mod greatly changes the gameplay of the game. You will be locked into a limited area that can be expanded. Expansion requires resources, the larger the territory, the more resources are needed for expansion.
That's not all, every night and sometimes during the day you will be attacked by waves of mobs whose goal is to destroy your core - the sheep. The waves will get stronger and stronger, mobs will start attacking with armor, weapons and effects, even riding spiders and bees! If the core is destroyed, your entire area will explode!
To build defense, the mod has turrets, different types that have different properties, each type of turret has 3 levels, the more the better.


The core can receive damage not only from mob attacks, but also simply from the fact that an enemy is nearby.
Download the mod if you want to get new experiences and emotions that you never got when playing regular Minecraft.
Is it possible to win?
With version 1.5 of the mod, the ability to win was added. To win, you need to make sure that the core does not take damage, and then you can find the Core Heart Pieces, and from them make the Core heart itself. If you use it on the core you will be free!
Worlds that were launched with a mod version lower than 1.4 will not be able to launch with a mod version 1.4 and higher
❗ Mod requires Fabric API ❗
