Forest Multiplayer Max Players & Raising the Limit

Forest Multiplayer Max Players & Raising the Limit

The Forest multiplayer mode officially supports up to 4 players in a single hosted game. You can raise this limit only by using a dedicated server with a mod or by installing a community-made plugin, as the base game does not offer an in-game slider for more players.

How Multiplayer Works in The Forest

The Forest uses a peer-to-peer system for its standard multiplayer. One player hosts the game, and up to three others can join that host directly through the in-game lobby or by invitation. The host’s computer acts as the server, meaning their internet connection and hardware determine the stability for everyone else. This 4-player cap is a deliberate design choice by the developers to keep the survival experience balanced and to limit the strain on a single host machine.

Why the Default Limit Is 4 Players

The 4-player cap is baked into the game’s core networking code. When the game was released in early access in 2014, the developers prioritized a stable co-op experience over large-scale multiplayer. The game’s AI, enemy spawning, and resource systems are all tuned for a small group. Pushing beyond 4 players without modification can cause noticeable performance drops, desynchronization, and AI behavior issues because the game engine was not designed to track more than four simultaneous players in a single world.

How to Raise the Limit to 8 or More Players

To play with more than 4 players, you need to run a dedicated server and apply a mod that removes the cap. The most common method is using the “More Players” mod available on community modding sites like Nexus Mods or the Steam Workshop. Here are the general steps:

  • Download a dedicated server tool for The Forest (either via the Steam “Dedicated Server” tool or by using a third-party hosting service).
  • Install the mod files into the server’s directory, following the mod’s specific instructions.
  • Edit the server configuration file (usually server.cfg or a similar text file) to set the maximum players to your desired number (e.g., 8, 12, or even 20).
  • Launch the dedicated server and have all players connect to that server’s IP address rather than joining a hosted game.

Note that mods are not officially supported, and the game may receive updates that break them. Always back up your save files before installing any mod.

Choosing Between Hosted Game and Dedicated Server

For 4 players, a standard hosted game is fine. For more than 4, a dedicated server is required because the game will not allow a player-host to exceed the cap. A dedicated server runs independently of any player’s client, so it can handle more connections without the host also rendering the game. If you are planning to play with 5 or more players, you must use a dedicated server. For 8+ players, you will also need a server with a strong CPU and at least 4 GB of RAM dedicated to the game.

Common Problems When Raising the Limit

Increasing the player cap often introduces issues. The most frequent problems are:

  • Desync: Players see each other in wrong positions or actions happen late. This is usually caused by the host’s upload speed being too low or the server’s CPU being overwhelmed.
  • Save corruption: Modded servers can corrupt save files if the mod is removed or if the game updates. Always keep backups.
  • Incompatibility: Some mods only work with specific game versions. Check the mod’s page for the exact patch number.
  • Connection timeouts: If the server is not port-forwarded correctly, players outside your local network cannot join. You will need to open TCP/UDP ports 8766, 27015, and 27016.

Performance and Hardware Considerations

Running a server for more than 4 players requires more than just a good gaming PC. The server needs a fast multi-core CPU, because the game’s simulation (enemy AI, resource respawning, building physics) runs on the server. For 8 players, a modern quad-core processor is the minimum. RAM usage scales with player count; expect around 1.5 GB for 4 players and up to 4 GB for 10+ players. Your internet upload speed is also critical—each player typically consumes 10-15 Kbps, but spikes occur during combat or building. A 10 Mbps upload connection is recommended for 8 players.

Alternatives to Modding

If you do not want to mod the game, you can still enjoy The Forest with more than 4 players by using a workaround: run multiple separate games on the same server and use a voice chat tool like Discord to coordinate. However, this is not a true single-world experience. Another alternative is to play Sons of the Forest, the sequel, which officially supports 8 players in a co-op session. If you are set on The Forest specifically, the modded dedicated server is the only real option.

Safety and Stability Tips

Modding any game carries risks. To stay safe:

  • Only download mods from reputable sites like Nexus Mods or the Steam Workshop—never from random pop-up ads.
  • Always scan downloaded files with antivirus software.
  • Keep a separate backup of your world save before enabling a mod.
  • Do not use mods on official servers (there are none for The Forest, but if you join a community server, respect its rules).

Also note that raising the player limit does not change the game’s difficulty scaling. More players means more enemies and more resource consumption, so the game may become chaotic. Test with a small group first to see if your server can handle it.

Frequently Asked Questions

Can I play with 8 players without a dedicated server?

No. The base game hard-caps at 4 players for a hosted game. To exceed that, you must use a dedicated server with a mod that removes the cap. There is no way to bypass it in the standard client.

Will raising the player limit affect my save file?

Yes, it can. If you load a save made with the mod and then remove the mod, the save may become corrupted or fail to load. Always keep a backup before switching mods or updating the game.

Is there a way to raise the limit without mods?

No. The 4-player cap is hardcoded. The only official way to play with more people is to play a different game, such as Sons of the Forest, which supports 8 players natively.

Do I need to port forward for a modded server?

Yes. If you want players from outside your local network to join, you must forward ports 8766 (Steam query), 27015 (game traffic), and 27016 (Steam master server). If you are using a hosting service, they handle this for you.

What is the maximum player count possible with mods?

Mods can theoretically allow up to 20 or more players, but the game engine becomes unstable beyond 10-12 players. Most mods recommend a maximum of 8-10 for a playable experience. Beyond that, you will encounter severe lag and frequent crashes.
