VEIN Server Config Explained: Game.ini and Engine.ini Settings

Where the VEIN config files are and how editing works

Both files sit in the same folder under the server install. On Windows that is ...\VEIN Dedicated Server\Vein\Saved\Config\WindowsServer\; on Linux it is Vein/Saved/Config/LinuxServer/. You may see the first file written in lower case (game.ini) on some Windows installs.

• Stop the server first. Unreal rewrites both files on shutdown, so edits made while it runs are lost.
• A missing line is the default. Unreal removes lines whose value matches the default, so a setting you wrote can disappear after a restart. That is normal.
• Settings are not stored in the save. Community references note that since 0.016 Hotfix 5, dedicated servers keep settings in these variables rather than in the world save, so a save moved to a new server does not bring its settings with it. Copy Engine.ini as well.

Game.ini: server name, password, player limit and visibility

A minimal Game.ini looks like this. Copy the section names exactly.

[/Script/Engine.GameSession]
MaxPlayers=16

[/Script/Vein.VeinGameSession]
ServerName=My VEIN Server
ServerDescription=Friendly co-op, PvP off
Password=
bPublic=True
SuperAdminSteamIDs=76561190000000000
AdminSteamIDs=76561190000000001
+AdminSteamIDs=76561190000000002

[OnlineSubsystemSteam]
GameServerQueryPort=27015

Defaults here come from host reference docs, not from the developer, and two of them vary by setup: a forum-posted working config used HeartbeatInterval=5.0, and the query port is set by launch argument on many hosts. Treat the table as "what you will usually see" and confirm in your own file.

Admins, super admins and whitelists

VEIN has no admin password. You become an admin because your SteamID64 is listed in Game.ini. Super admins can additionally grant and remove admin rights from the in-game admin menu. List the first ID on its own line and prefix further IDs with + so Unreal appends them to the array instead of overwriting it, as in the example above.

The whitelist uses the same pattern, with WhitelistedPlayers under [/Script/Vein.VeinGameStateBase]. Once any ID is on it, everyone else is refused, so add yourself and your admins before restarting.

Admin commands and the admin menu (opened with the \ key in game) are covered in community command lists; there is no "cheats enabled" switch, since only admins can run those commands on a multiplayer server.

Engine.ini: gameplay rules as vein.* variables

Every gameplay rule is a console variable written under [ConsoleVariables] in Engine.ini. The full list of vein.* variables runs to more than 250 entries. These are the ones most servers actually change, with the defaults the game reports:

[ConsoleVariables]
vein.PvP=0
vein.Zombies.Health=60
vein.Scarcity.Difficulty=3
vein.Time.TimeMultiplier=8
vein.Autosave.Interval=300

Values appear as 1.000000 in the game's own dump, but plain numbers such as 1 are accepted in config files.

Changing settings without restarting

Admins can change gameplay settings live from the in-game admin menu, in its Config section, which is the safest way to test a value before committing it to Engine.ini. Anything you want to survive a wipe, a reinstall or a move to another host still has to be in the config files.

If your server is hosted, the same two files are edited through your host's tools or over SFTP. Hosting with ChicagoServers? The Vein server hosting page lists what is included, such as free server backups and SFTP file access.
