Survive 100 days of escalating zombie sieges — the Forge Labs formula as a pack.

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.
One click — the pack and its Forge loader install automatically.
Everyone installs the pack from Modrinth at the server's version and joins your address.
Day 1 walls are not optional. Assign a farmer early — food runs out faster than ammo.
6 GB is our honest sizing for Zombie Invade 100 Days. Start here — upgrading later is one click and your world comes with you.
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.
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.
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.
Name it, pick a plan, and Zombie Invade 100 Days installs itself. That is the whole setup.
