Zombieium

Zombieium turns Minecraft nights into a focused zombie survival experience.

While enabled, the mod:

• Spawns vanilla Zombies around players at night (configurable distance, interval, amount, and nearby cap)
• (Optionally) keeps the Overworld hostile-mob roster “zombie-only” by removing other hostile mobs as they load
• Adds a Boss Event: after midnight, a red beam marks a player—and when it ends, Zombieium arrives (bossbar, buffs, boosted stats, and dramatic arrival effects)
