Undead Alliance
by RealNamanOP
Undead Alliance lets players turn zombies into loyal companions that follow them, guard them and fight alongside them in survival play.
What it does
Zombies recruited through the mod gain a personality and a trust value that moves between hostile and loyal. Trust depends on how a zombie is treated, and the tiers set how it acts: below 20 it breaks the alliance, from 20 to 49 it is suspicious and may retaliate, from 50 to 79 it follows the player and protects them, and from 80 to 100 it acts loyally. The AI prioritizes survival and tends to stay close to its owner.
Recruitment is made easier in the mod's own settings, and the combat style is more aggressive than vanilla zombies. The mod is marked as under development, so the author lists encountered bugs, unfinished behaviors and balancing issues as known matters, with updates planned to improve stability and AI behavior.
Undead Alliance runs on client and server, so the server and every player need it. It requires Fabric API and is published for Fabric only, for 1.21.1. The code is not open source; the mod is released under All rights reserved.
