How to Adjust the Most Important Gameplay Settings on Your SCP: Secret Laboratory Server

Adjust the most important gameplay settings on a SCP: Secret Laboratory server

The config_gameplay.txt file controls how your server behaves in-game. This guide bundles the most important settings for the intercom, AFK kick, idle mode, spawn protection, round restarts and broadcasts – each with a short overview of the keys and a ready-to-use recipe.

Prerequisite

The guide Edit configuration files shows you where the configuration files are located, how to edit them and how to apply changes safely. All settings in this guide belong in the following file – replace <Port> with the game port of your server shown in the Overview of the dashboard:

/.config/SCP Secret Laboratory/config/<Port>/config_gameplay.txt

Intercom

The intercom lets players make an announcement to everyone. These keys control how long players may speak and how long the intercom is locked afterwards:

Key Default Effect
intercom_cooldown 120 Time in seconds before the intercom becomes available again after an announcement
intercom_max_speech_time 20 Maximum speech time in seconds per announcement

Recipe – longer announcements, shorter cooldown:

intercom_max_speech_time: 30
intercom_cooldown: 60

AFK Kick and Idle Mode

AFK kick

Inactive players are removed from the server automatically:

Key Default Effect
afk_time 90 Time in seconds until an inactive player is kicked – SCP-079 gets an extra 13 seconds
constantly_check_afk false Enables the constant AFK check
afk_kick_message AFK Message shown to the kicked player

Recipe – more patience with inactive players and a clearer kick message:

afk_time: 180
afk_kick_message: You have been removed from the server for inactivity.

Idle mode

In idle mode, the server lowers its tickrate while nobody is connected – this saves CPU resources on empty servers:

Key Default Effect
idle_mode_enabled false Enables or disables idle mode
idle_mode_time 5000 Time in milliseconds until idle mode activates
idle_mode_preauth_time 30000 Idle mode wait time in milliseconds after a connection attempt (preauth)
idle_mode_tickrate 1 Tickrate of the server while in idle mode

Recipe – save CPU while the server is empty:

idle_mode_enabled: true

You can leave the remaining idle mode values at their defaults.

Spawn Protection

Spawn protection keeps freshly spawned reinforcements from being killed right as they enter the game:

Key Default Effect
spawn_protect_enabled false Enables spawn protection
spawn_protect_time 8 Spawn protection length in seconds
spawn_protect_can_shoot false Controls whether protected players may shoot – by default, protection ends as soon as a player equips a firearm
spawn_protect_prevent_all false Set to true, the protection blocks all damage; by default only friendly fire damage is blocked
spawn_protect_team 1, 2 Teams with spawn protection – 1 = MTF, 2 = Chaos Insurgency

Recipe – enable spawn protection for reinforcements:

spawn_protect_enabled: true
spawn_protect_time: 10

Round Restarts

These keys control what happens after a round ends and whether late joiners still spawn in:

Key Default Effect
auto_round_restart_time 10 Time in seconds between the end of a round and the automatic round restart
restart_after_rounds 0 Full server restart after the specified number of rounds – 0 disables the feature
enable_fast_round_restart false Enables the fast round restart – according to the official reference, this feature can be buggy
fast_round_restart_delay 3.2 Delay of the fast round restart
late_join_time 0 Time in seconds after the round starts during which newly joining players still spawn in

Recipe – free up memory regularly: A full server restart every few rounds counteracts slowly growing memory usage. Since your server runs behind LocalAdmin, it is restarted automatically after shutting down – you do not have to do anything in the dashboard.

restart_after_rounds: 15

Broadcasts for Kicks and Bans

Your server can show a message to all players when someone is kicked or banned. The guide Kick and ban players shows you how to kick and ban players.

Key Default Effect
broadcast_bans true Shows a broadcast message when a player is banned
broadcast_ban_text %nick% has been banned from this server. Text of the ban message – %nick% is replaced with the player name
broadcast_ban_duration 5 Display duration of the ban message in seconds
broadcast_kicks false Shows a broadcast message when a player is kicked
broadcast_kick_text %nick% has been kicked from this server. Text of the kick message – %nick% is replaced with the player name
broadcast_kick_duration 5 Display duration of the kick message in seconds

Recipe – enable kick broadcasts with custom messages:

broadcast_kicks: true
broadcast_kick_text: %nick% was kicked from this server.
broadcast_ban_text: %nick% was banned from this server.
