This guide covers the zmrserver module in AlphaGSM.

Requirements

screen
SteamCMD runtime libraries (lib32gcc-s1, lib32stdc++6)
Python packages from requirements.txt
The official Zombie Master: Reborn Beta 6 Linux archive, zombie_master_reborn_b6_1.tar.gz, linked from zombiemaster.dev, extracted under <install_dir>/zombie_master_reborn/

Support Status

zmrserver is supported in ENABLED (BYO) mode. AlphaGSM installs Steam app 244310 from the anonymous previous2021 branch. That legacy SDK 2013 dedicated branch is the 32-bit launcher this game can start. The public branch of the same app does not finish startup. The install still needs the official Linux archive linked from the project page. App 244310 publishes bin/*_srv.so. prestart copies those onto the unsuffixed names srcds_linux loads, restores the launcher execute bit, and writes sv_hibernate_when_empty 0. This dedicated build reports that cvar as an unknown command. A local process start still answered A2S on UDP 42202 (map zm_docksofthedead, 0/16). The A2S hostname was AlphaGSM Zombie Master: Reborn. The process was stopped and that UDP port was free. Docker was not run.

Quick Start

Create the server:

alphagsm myzmrserve create zmrserver

Run setup:

alphagsm myzmrserve setup

Start it:

alphagsm myzmrserve start

Check it:

alphagsm myzmrserve status

Stop it:

alphagsm myzmrserve stop

Setup Details

Setup configures:

the game port (default 27015)
the install directory
the executable name
SteamCMD downloads the server files
default configuration and backup settings

Before start, download the Linux archive linked from the official project page and extract the resulting zombie_master_reborn/ tree so <install_dir>/zombie_master_reborn/maps/zm_docksofthedead.bsp exists. Keep every multiplayer map. If setup or start reports an ENABLED (BYO) requirement, app 244310 on previous2021 is still only the SDK scaffold.

Useful Commands

alphagsm myzmrserve update
alphagsm myzmrserve backup

Notes

Module name: zmrserver
Default port: 27015

Maps and Mods

Map directory: zombie_master_reborn/maps/
Mod directory: zombie_master_reborn/addons/
Workshop support: No
Mod notes: AlphaGSM now supports manifest, direct archive url, gamebanana, and moddb addon sources for this server through the shared Source addon flow. The built-in manifest currently includes metamod and sourcemod. mod cleanup removes only AlphaGSM-tracked addon files and keeps cache/state under .alphagsm/mods/zombie_master_reborn/.
Current status: Supported in ENABLED (BYO) mode. Anonymous SteamCMD app 244310 on previous2021 provides the 32-bit SDK scaffold, and the official Linux archive linked from the project page provides zombie_master_reborn/. Local process A2S was validated on UDP 42202 (map zm_docksofthedead, 0/16) and the server was stopped. Docker was not run.
Map install: Copy .bsp files into zombie_master_reborn/maps/ and add to zombie_master_reborn/cfg/mapcycle.txt.
Mod install: Copy addon folders into zombie_master_reborn/addons/.

BYO file helper

Inspect this game's required files, source instructions and destinations with alphagsm <server-name> assets requirements; check the declared files with alphagsm <server-name> assets check. File checks do not establish game readiness. This helper checks known sentinels only and directs you to stage the complete compatible distribution manually; managed import is unavailable for this recipe. See BYO files and private SteamCMD acquisition.
