DeceasedCraft server hosting & setup guide
A DeceasedCraft server needs Java 17 and about 9–11 GB of RAM for up to 8 players.
A zombie-apocalypse survival pack on Forge inspired by Project Zomboid and 7 Days to Die: loot procedurally generated cities, hold out against hordes that grow stronger over time, and work up through Create and Immersive Engineering tech.
Pack details checked by hand against DeceasedCraft on CurseForge on October 5, 2026.
DeceasedCraft is a Forge modpack for Minecraft 1.20.1 (older versions go back to 1.18.2) with 306 mods. We'd pick our Heavy plan (12 GB) for it.
- The authors say command blocks must be enabled on a server, because features such as multiblocks and vehicle spawns depend on them. Set enable-command-block=true in server.properties.
- Versions 5.10 and later are an open beta on Minecraft 1.20.1 that can't be finished yet, because the Wasteland and Abyss districts, and with them the endgame, aren't in it. For the complete game the authors point players to version 5.5.5 on Minecraft 1.18.2, which has its own server files. Both run on Java 17, and the pack's wiki warns that Java 22 won't work.
- The authors advise against LAN play, citing poor performance and bugs, and recommend hosting a server with the pack's server files instead.
- The Distant Horizons edition of the beta asks for 12 GB or more on the server, so it may need more than our biggest plan.
- Players should install the pack through a launcher, not from the server pack: the authors say the server pack leaves out the client's optimization mods.

DeceasedCraft server files
DeceasedCraft's authors publish official server files. Published next to each version on CurseForge, for example DeceasedCraft_Server_Beta_5.10.17.zip for the 5.10.17 beta and DeceasedCraft_Server_v5.5.5.zip for the finished 5.5.5. Get the official server files.
Use the server files for the exact version your players install: a server and client on different pack versions won't connect.
How much RAM does a DeceasedCraft server need?
| Players online | RAM | DSN plan |
|---|---|---|
| 1–3 players | About 8–9 GB | Heavy (12 GB)Premium (8 GB) can do if players stay close. |
| 4–8 players | About 9–11 GB | Heavy (12 GB) |
| 9–15 players | About 10.5–13.5 GB | Heavy (12 GB) if players stay closeMore than 12 GB if they spread out. |
Estimated from 306 mods with our RAM calculator, set against the authors' own advice, not measured: low end if players stay together, high end if they spread out. What the authors say: The authors ask for at least 8 GB for a server and recommend 10 GB or more, or 12 GB or more for the Distant Horizons edition.
With 9–15 players spread across the map, DeceasedCraft can need more than 12 GB, our biggest plan. A lower view distance and a pre-generated world help it fit; past that, a host with bigger plans is the better choice.
Set Java's heap (-Xmx) 10–15% under the RAM you have, about -Xmx10500M on 12 GB. Forge 1.20.1 reads it from user_jvm_args.txt: uncomment the -Xmx line. RAM guide.

How to play DeceasedCraft with friends
Each player installs DeceasedCraft with the CurseForge app or Prism Launcher, the same version as the server, and adds the server's address under Multiplayer.
Different versions of DeceasedCraft on the server and a client show up as Mismatched mod channel list or mod rejections. Why friends can't join, timeouts included.
Lag and performance on DeceasedCraft
Can't keep up! Is the server overloaded? means ticks take longer than 50 ms; more RAM won't fix that once DeceasedCraft has enough (tick lag guide). For DeceasedCraft:
- Measure first: spark's
/spark tpsand profiler work on 1.20.1 and name the mod or machine using the tick time. - Distances:
view-distance=8and a lowersimulation-distanceinserver.properties. - Pre-generate: Chunky for 1.20.1,
/chunky radius 3000then/chunky start, before people explore. - Chunk loaders keep machines running with nobody nearby; in a pack this size, dozens add up.
