Archean offers a multiplayer experience, allowing you to open your single-player games to other players or set up a dedicated server.

Hardware Requirements

To ensure the proper functioning of an Archean server in multiplayer mode, the following minimum configuration is recommended:

Processor: Prioritize high power per core (i7, Ryzen...)
Memory: Minimum of 8 GB of RAM

This setup may change depending on the platform used (Windows, Linux, etc.) and future game updates.

Network

Regardless of the operating system choice, you must ensure that port 8881 is open for both UDP & TCP.

Setting Up a Server

Docker

To set up a dedicated server on a Linux server, you will need curl as well as Docker in order to execute the automatic installation script.

Installing Docker can significantly vary depending on the distribution used. We recommend consulting the Wiki of your distribution for guidance on successful installation.

To install the server with the official script, here are the steps to follow:

# Download the install script
curl -s -o install_archean_server.sh https://archean.space/assets/user_scripts/run_server_with_docker.sh

# Make it executable
chmod +x install_archean_server.sh

# Run this script to Install or Update the server
./install_archean_server.sh

Note: It is possible to use this method on Windows using WSL (Windows Subsystem for Linux), but some users have encountered potential performance issues.

Manual Installation

For both Linux and Windows, a standalone executable is available to run an Archean server.

To start the server, simply run the Archean_server[.exe] file located in the Archean-game folder. The server will launch in console mode and will ask you for a series of information to configure it. This information will no longer be requested once the server_public_name value is set in the server.ini file.

Allow Access to Your Single-Player Game

You can allow access to your single-player game if you manually configure the server.ini file with the following parameters:

server_online = yes
server_public_name = <Any name you want>
accept_remote_connections = yes

Then, each time you press Play in the launcher, a public server will be listed and other players will be able to join you.

Don't forget to open your port 8881 (or any other port you have configured in listen_port).

You do not have to set the server_online parameter to yes to allow other players to join your game. You can also invite them by giving them your IP address and the port of your server, which they will need to enter manually in the game launcher. You only need to set accept_remote_connections = yes.

Managing Administrators

Information

An administration panel is accessible in the game with the F4 key. It displays the server load and its speed in ticks per second. (25 ticks/s being the default maximum tick rate guaranteeing optimal performance)

A checkbox Admin Privileges allows, among other things, to spawn blueprints for free when the game mode is set to Adventure.

The panel also offers two tabs:

Players: Allows you to see the list of connected players, teleport to them, and/or kick them.
Entities: Allows you to see the list of entities present on the server, delete them, and/or teleport to them.

Adding/Removing an Administrator

To add an administrator, simply modify the file /Archean-data/server/admins.txt. This file should contain a list of player IDs, one per line. If the player uses Steam, their Steam64 ID should be used.
