How to Configure Your SCP: Secret Laboratory Server

Last updated: September 18, 2026

Almost everything about how your SCP: Secret Laboratory server plays is controlled by config_gameplay.txt. This guide covers the most useful settings and how to apply them safely.

Before You Edit

  1. Log in to the NolimitHost Game Panel and stop your server from the Console page.
  2. In the left sidebar, click Files and open the config folder for your port, for example /.config/SCP Secret Laboratory/config/7777/.
  3. Open config_gameplay.txt. Each setting is written as key: value on its own line, and lines beginning with # are comments.
  4. Save your changes, then start the server again to apply them.
Important: The folder name is your server's port, so if your server runs on 7778 you must edit the 7778 folder. SCP:SL does not hot-reload - any change only takes effect after a restart.

Common Settings

Setting Default Description
server_name(empty)Name shown in the server browser. Supports rich-text tags. See Change the Server Name.
max_players20Maximum number of players connected at once.
server_port7777UDP port the server listens on. Must match the port allocated in the panel.
server_password(empty)Join password. Leave empty for a public server.
server_tickrate60Server simulation rate. Leave at the default unless you are tuning performance.
friendly_firefalseAllow players to damage teammates.
friendly_fire_multiplier0.4Damage multiplier applied to teammates.
intercom_cooldown120Seconds a player must wait before using the intercom again.
intercom_max_speech_time20Maximum seconds of intercom speech.
auto_round_restart_time10Seconds to wait before the round restarts automatically.
warhead_tminus_start_duration90Length of the warhead countdown in seconds (allowed range 70 - 120).
use_reserved_slotstrueEnable reserved slots, tied to UserIDReservedSlots.txt.
afk_time90Seconds before a player is marked as AFK.
Note: Exact defaults and available keys can change between game versions. If a key is not present in your file, add it on its own line rather than assuming a value.

Admin and Moderation Settings

Admin roles, permissions, and bans are handled in a separate file, config_remoteadmin.txt. See Become an Admin to add yourself and your staff.

Applying Your Changes

Start the server from the Console page. If a change does not appear to take effect, confirm you edited the folder matching your server's port and that the server was fully stopped before you saved.
