How To Play Unturned With Friends: The Ultimate Multiplayer Setup Guide
Playing multiplayer in Unturned requires selecting a networking method that matches your group size, technical comfort, and budget. You can host directly through the built-in Steam matchmaking menu, spin up a dedicated server for 24/7 persistent survival, or rent a third-party server to avoid port-forwarding configurations.
Preparation & Prerequisites for Unturned Multiplayer
Setting up a seamless multiplayer session in Unturned requires understanding the game's peer-to-peer and dedicated server architecture. Before inviting your friends into a post-apocalyptic world overrun by zombies, you must align your game versions, verify firewall permissions, and ensure your system resources can handle hosting overhead.
- Essential Tools & Software: Steam client, Unturned installed on all participating machines, and optionally the Unturned Dedicated Server tool available via the Steam Tools library.
- Prerequisite Knowledge & Standards: Basic familiarity with networking concepts such as local IP addresses, port forwarding (specifically TCP/UDP port 27015), and the difference between listening servers and dedicated servers.
- Estimated Setup Duration & Cost: 5 to 15 minutes for basic Steam/LAN hosting; 30 to 45 minutes for dedicated server setup. All methods are free unless you choose to rent third-party server hosting.
Step-by-Step Guide to Hosting and Joining Unturned Multiplayer Sessions
Step 1: Choose Your Hosting Method and Launch the Game
Determine whether you will host a session directly from your client machine or use a separate dedicated server application. If you have fewer than four players and do not require the server to run when you are offline, hosting a listening server directly through the game client is the fastest approach. Launch Unturned from Steam, navigate to the Play menu, and select Host to initialize the server configuration parameters.
Step 2: Configure Server Settings and Security Parameters
Customize your world by selecting the desired map (such as PEI, Washington, or Russia), game difficulty mode (Easy, Normal, Hard, or Gold), and perspective rules (First Person, Third Person, or Both). Crucially, assign a secure server password if you wish to keep uninvited players out of your session. Toggle the Batista anti-cheat option to on to prevent unauthorized modifications or exploits on your server instance.
Step 3: Configure Ports and Network Access
If you are hosting a public or internet-accessible session through your local machine, you must configure your home router to forward traffic properly. Log into your router admin panel and forward port 27015 using both TCP and UDP protocols to your local machine's IPv4 address. Additionally, verify that your Windows Defender Firewall or third-party antivirus software allows incoming and outgoing connections for Unturned and its associated server executables.
Step 4: Connect and Invite Your Friends
Once the server finishes loading the map and initializing the environment, have your friends launch their games and navigate to the Connect menu. They can join your session by entering your public IP address and the designated port number, or by finding your server listed under the Internet tab if public matchmaking broadcasting is enabled. Alternatively, you can send them a direct Steam invite if they are on your friends list and the session visibility is set to friends-only.
Pro-Tip: If you experience severe connection timeouts or friends cannot see your server in the browser list, verify your Windows network profile is set to "Private" rather than "Public," as public profiles aggressively block incoming peer-to-peer traffic.

Comparison of Unturned Multiplayer Hosting Methods
| Hosting Method | Hardware Requirement | Port Forwarding Needed? | Persistent 24/7 Uptime | Recommended Player Count |
|---|---|---|---|---|
| Client Host (Listen Server) | Moderate (Host PC runs game and server) | Yes (Unless LAN or Hamachi) | No (Shuts down when host exits) | 1 to 4 Players |
| Dedicated Server (Local) | High (Dedicated PC or powerful rig) | Yes | Yes (Runs independently) | 4 to 24+ Players |
| Third-Party Server Hosting | None (Cloud-hosted by provider) | No | Yes (Managed via web control panel) | 4 to 32+ Players |
Common Connection Failures and Field Fixes
- Root Cause: Friends receive a "Timed Out" or "Failed to Connect" error when trying to join your hosted session. Actionable Fix: Confirm that your router's port forwarding rules accurately point to your current local IPv4 address, as dynamic IP assignments can change your machine's address after a reboot.
- Root Cause: Players encounter a "BattlEye Mismatch" or version discrepancy error upon joining. Actionable Fix: Verify game file integrity through Steam on both the host and client machines to ensure everyone is running the exact same game update and anti-cheat binaries.
- Root Cause: The server does not appear in the global Internet server browser list. Actionable Fix: Ensure that the server config file explicitly has the server visibility parameter set to public and that ports 27015 through 27017 are fully opened in your firewall settings.
Frequently Asked Questions
Can I play Unturned multiplayer without port forwarding?
Yes, you can play with friends without configuring port forwarding by utilizing third-party virtual private network software like Hamachi or Radmin VPN, or by renting a dedicated server from an external hosting provider. These methods bypass standard home router restrictions by creating a secure virtual local area network among connected users.
How many players can join a single Unturned server?
While the default game client allows smaller groups of friends to play together seamlessly, dedicated servers can theoretically support up to 24 or more concurrent players depending on hardware capabilities, map size, and server-side performance optimization. Exceeding recommended player counts on lower-end hardware can introduce severe rubberbanding and latency spikes.
Are mods compatible when playing with friends?
Mods are fully compatible in multiplayer, but all participating players must subscribe to and download the exact same collection of workshop items before attempting to join the server. If a client attempts to connect with a mismatched mod list or missing workshop files, the game will automatically disconnect them with an asset mismatch error.
Is it possible to host an Unturned server on a separate PC?
Yes, you can install the Unturned Dedicated Server tool on an old laptop or secondary home computer using your Steam account to run a dedicated environment. This prevents the host computer from suffering performance drops caused by running both the client game and the server simulation simultaneously.
