How To Play With Friends In Unturned: The Complete Multiplayer Setup Guide
Playing multiplayer in Unturned requires understanding your networking options, configuring ports or Steam lobbies correctly, and aligning game versions with your friends. Whether you choose to host a quick peer-to-peer session, spin up a dedicated server via Steam, or rent external server hosting, proper configuration ensures minimal lag and a seamless survival experience.
Essential Preparation and Network Requirements for Unturned Multiplayer
Setting up a stable multiplayer session in Unturned involves evaluating your hardware capabilities, network bandwidth, and administrative settings. Because Unturned relies heavily on the host's CPU and upload speed for peer-to-peer or local dedicated servers, understanding your network baseline prevents mid-game desync, rubberbanding, and connection timeouts.
- Essential Gear and Tools: A stable broadband internet connection with a minimum of 5 Mbps upload speed for hosting, the Steam client for all participating players, and optionally, the Unturned Dedicated Server tool downloaded via Steam tools.
- Mandatory Prerequisites: All players must run the exact same version of Unturned, including matching checksums for any active curated or workshop mods. Firewall and antivirus software must permit Unturned through private and public profiles.
- Estimated Setup Duration: 10 to 15 minutes for basic Steam group lobbies or peer-to-peer hosting; 30 to 45 minutes if configuring a dedicated port-forwarded server.
Step-by-Step Instructions to Host and Join Friends in Unturned
Step 1: Choosing Your Multiplayer Hosting Method
Determine whether you want a casual drop-in session or a persistent world. For casual sessions with two to four players, the in-game host menu utilizing Steam matchmaking is the fastest route. For persistent worlds where friends can log in even when you are offline, you must set up a dedicated server using the command-line interface or third-party hosting providers. Navigate to the Play menu in Unturned, select Host, and choose between a Singleplayer-hosted server or a dedicated instance.
Pro-Tip: If your friends encounter infinite loading screens while joining your hosted session, verify that your Windows Firewall or third-party security software is not blocking inbound connections on default ports.
Step 2: Configuring Server Parameters and Security Settings
If you are hosting through the in-game menu, configure your server name, map selection (such as PEI, Washington, or Russia), game difficulty (Easy, Normal, Hard, or Gold), and maximum player count. Crucially, set a robust password if you want to keep random players out, or toggle the "Steam Networking" option to restrict access solely to your Steam friends list. If you are operating a dedicated server via the Command Prompt, edit your Server.ini file to lock down access controls, enable BattlEye anti-cheat, and define administrative SteamIDs.
Warning: Leaving a dedicated server open to the public without enabling BattlEye anti-cheat or configuring admin authentication leaves your world vulnerable to malicious script executors and griefers.
Step 3: Managing Network Port Forwarding (For Dedicated Servers)
If you opted for a dedicated server rather than a casual Steam-invited lobby, you must forward the correct network ports through your home router. Access your router's administrative dashboard via your default gateway IP address in a web browser. Locate the Port Forwarding or Virtual Server section and create a new rule for TCP and UDP protocols. By default, Unturned utilizes port 27015, with query ports typically sitting at 27016 and Steam workshop ports at 27017. Input your local machine's internal IPv4 address as the destination target.
Step 4: Connecting with Your Friends
Once the server is running and accessible, distribute your connection credentials to your group. For Steam-invited sessions, friends simply need to open their Steam overlay, right-click your profile name, and select "Join Game." For dedicated servers, your friends must launch Unturned, navigate to Play, select Connect, and enter your public IPv4 address alongside the designated port number. Alternatively, add the server to your Steam Server Favorites list via the Steam View menu to bypass in-game browser limitations.

Troubleshooting Common Unturned Connection Failures
- Root Cause (Timed Out / Failed to Connect): The host's router is blocking incoming traffic, or the server IP address changed due to dynamic DHCP leases.
- Actionable Fix: Ensure static IP addressing is enabled on the host machine and verify that port forwarding rules correctly map ports 27015 through 27017 to the correct local IPv4 address.
- Root Cause (Mismatched Version / Assets): Participating players are running an outdated version of the game or have conflicting Steam Workshop modifications installed.
- Actionable Fix: Have all players verify integrity of game files via Steam, disable non-essential client-side mods, and ensure the server updates immediately following official game patches.
- Root Cause (BattlEye Initialization Failure): The anti-cheat software failed to load correctly upon game startup, preventing entry onto protected servers.
- Actionable Fix: Navigate to your Unturned directory via Steam, locate the BattlEye folder, and run the Install_BattlEye.bat script as an administrator.
Frequently Asked Questions
Can I play Unturned multiplayer without port forwarding?
Yes, you can use the in-game host feature combined with Steam Networking. This allows your friends to join directly through your Steam profile or invite list without requiring any manual router configuration.
How many players can join a single Unturned server?
The default player limit is typically 24 players for performance and map balance reasons. However, server administrators can modify the max players value in the server configuration files, though higher counts require significant server CPU power and bandwidth.
Why won't my friends show up in my hosted game world?
This usually stems from privacy settings on Steam or mismatched game versions. Ensure your Steam status is set to Online, your friends are actively on your friends list, and both the host and clients have updated their games to the exact same build.
Are mods required to play multiplayer with friends?
No, vanilla Unturned requires zero modifications to play cooperatively. If you choose to install workshop maps, vehicles, or weapons, every player joining the server must subscribe to and download the exact same mod collection prior to connection.
Mastering Unturned multiplayer setups opens up endless cooperative survival possibilities with your circle. Secure your server environment, sync your game versions, and jump into the apocalypse together today.
