ZApocalypse
by Swin
ZApocalypse turns the night into a zombie wave on Fabric 1.21.1, with elite variants, a boss and mobs that gain abilities as the nights go on.
What it does
Every few nights a larger zombie wave arrives, and the third of those waves is a blood night. After wave 9 the rage phase begins, and zombies gain unique abilities in place of simple stat boosts. Other hostile mobs retreat into deeper caves when the apocalypse escalates, so the danger shifts underground as well as on the surface.
The mod adds several new zombie types, including Speedy, Titan, Summoner, Poison, Pest, Builder and Leech, some of which appear in daytime. A Zombie Lord boss comes in on blood nights, bringing summoned units and a TNT bombardment. Installation needs Fabric only, and the mod runs on the server, so players join without installing anything. Files are published for 1.21.1, with 1.0.0 as the latest build from 2026-03-12, under the MIT License.
Key features
Wave nights
Night zombie waves grow in size, with small waves, big waves and a larger wave on every third night.
Blood nights
Blood nights bring the strongest waves and the Zombie Lord boss, which summons units and drops TNT from above.
Evolving zombies
After wave 9 zombies gain unique abilities, so the threat changes in kind rather than only in strength.
Named zombie types
Speedy, Titan, Summoner, Poison, Pest, Builder and Leech each behave differently, and some appear during the day.

Who it’s for: Server owners and survival players on Fabric 1.21.1 who want zombies that escalate over many nights, with a boss and new mob types that appear across the day and the underground.
How it compares
Zombieium is a Fabric mod for 1.21.11 that needs both the client and the server, and it is released under a custom license. Zombie Enhanced is a Fabric mod for 1.21.1 that runs on the server only, and it is licensed as All rights reserved, so it is not open source. ZApocalypse also runs on the server only, but its license is the MIT License, which is not open source in the catalog's sense.
