WHY ZOMBIE INVADE 100 DAYS ON A SERVER

The "100 days in a zombie apocalypse" challenge, packaged: hordes escalate night by night, guns and barricades are your economy, and the goal is simply to still be alive at day 100. It's the most-downloaded survival-challenge pack on Modrinth for a reason.

As a server it turns into a proper co-op campaign — base defense assigns itself into roles (builder, gunner, farmer) and a breached wall at day 60 is a group memory.

Best co-op survival challenge

From zero to playing in three steps

STEP 1

Create the server

One click — the pack and its Forge loader install automatically.

STEP 2

Sync your squad

Everyone installs the pack from Modrinth at the server's version and joins your address.

STEP 3

Fortify before dark

Day 1 walls are not optional. Assign a farmer early — food runs out faster than ammo.

Questions, answered.

How much RAM does this pack's server need?+

6 GB — horde nights spawn a lot of entities at once, and that's the load that matters. Guaranteed CPU keeps the horde ticking smoothly instead of rubber-banding.

Does the 100-day timer work in multiplayer?+

Yes — the day counter is world time, shared by everyone. Sleeping skips nights only if the server's sleep rules allow it, so decide as a group whether skipping is cheating.

What happens if we all die?+

You respawn and the siege continues — but your gear is wherever the horde is. Automatic daily backups let you roll the world back to before the wipe if the group votes for it.
