Zombie Survival Mod (ZSM)
by Jungdab
Zombie Survival Mod (ZSM) turns vanilla Minecraft into a ten-day survival challenge built around waves of zombies and a final boss.
What it does
Players must survive ten in-game days while fighting zombies that each have their own abilities. As days pass, stronger zombies and more mobs spawn, building toward a final boss at the end. Zombies spawn mainly at night, so the daytime is the window for crafting items, building defenses and preparing a stronghold.
Players craft gear and shelter, face several prepared challenges, and can recover after death: a corpse is left behind that can be broken to respawn. Mobs detect players from up to 200 blocks away, even through solid blocks, and players can move quickly on water. Sleeping in beds lets the night pass for everyone, and the Nether cannot be used to escape the threat.
Installation requires Geckolib version 4.6.6 or higher on Fabric. The server and every player need the mod installed. Files are published for Fabric only, for 1.21.1 and 1.21.4, with 1.0.1+1.21.4 for 1.21.4 as the latest build, under the MIT License as open source.
Key features
Ten-day survival
The run is organized around ten in-game days, with the threat growing each day until the final boss appears.
Escalating zombies
Zombies with unique abilities appear in larger numbers and greater strength as the days progress.
Corpse recovery
On death, a corpse is left behind, and breaking it returns the player to the respawn point.
Night-based spawning
Zombies appear at night, while the earliest basic zombies can spawn from day one.
