Cursed Walking server hosting & setup guide
A Cursed Walking server needs Java 17 and about 7–8 GB of RAM for up to 3 players.
A zombie-apocalypse pack on Forge 1.20.1: zombies that climb on each other, attack in hordes every ten days and can infect you, stronger variants as the days go on, cities and bunkers to loot, Timeless and Classics Zero guns, and an endgame dimension called the Depths.
Pack details checked by hand against Cursed Walking on CurseForge on October 5, 2026.
Cursed Walking is a Forge modpack for Minecraft 1.20.1 with 239 mods. We'd pick our Premium plan (8 GB) for it.
- Not every release on CurseForge has a server pack: version 3.3 doesn't, but 3.3 (patch) does, so pick a version that has one.
- Older Cursed Walking lines for Minecraft 1.19.2, 1.18.2 and 1.16.5 are still on CurseForge but haven't been updated since 2023 or 2024; this guide covers the 1.20.1 version.
