Schedule I has been one of the bestselling games of 2026. The built-in co-op supports up to 4 players, but with a dedicated server you can expand that significantly. This guide covers everything you need to know.
Why Run a Dedicated Server?
The built-in co-op works well for small groups but has limitations. A dedicated server gives you:
- More than 4 simultaneous players (up to 8-12 depending on the build)
- 24/7 uptime, even when the host is offline
- Better performance since the server does not run on the same machine as a player
- Support for mods and custom scenarios
How much RAM does a Schedule I server need?
A Schedule I dedicated server needs at least 4 GB of RAM for 4 players. For 8 players, we recommend 6 GB, and for 12 players, 8 GB. The game loads many assets into memory, so more RAM helps. CPU: minimum 2 cores, preferably with high single-thread performance.
Installation via SteamCMD
The dedicated server tool is available through SteamCMD. On a VPS or game server:
- Install SteamCMD on your server
- Log in as anonymous:
login anonymous - Set the install directory:
force_install_dir /opt/schedule1-server - Install the server:
app_update [APP_ID] validate - Start the server with the included start script
Server Configuration
In the configuration file, you can adjust various settings:
- MaxPlayers - Maximum number of players (default 4)
- ServerName - The name shown in the server browser
- SaveInterval - How often the world is saved (in seconds)
- DayLength - The length of an in-game day
Can I install mods on a Schedule I server?
Yes, Schedule I supports mods through the Steam Workshop and manual installation. Upload mod files to the Mods folder on your server and restart. Important: all players must have the same mods as the server.
