Sons of the Forest Part 2 Story Expansion: Server Admin Guide

Sons of the Forest Part 2 Story Expansion: Server Admin Guide

The highly anticipated Sons of the Forest: Part 2 expansion dramatically expands the underground Bunker-City network, introduces new Kelvin companion behaviours, and adds the cryptic Second Cube — a late-game enigma that unlocks co-op-exclusive endings. For dedicated server operators, this update brings new save structure changes and optional progression flags that need administration.

🗂️ New Save Structure

Part 2 adds new save folders: Saves/Multiplayer/[ID]/Part2/. Backup your existing server saves before applying the update to prevent data conflicts.

🔐 Holo-Key Persistence

Holo-Keys are now per-player tracked server-side. If a player loses their key data due to corruption, admins can inject keys via the new /giveitem HoloKey [SteamID] RCON command.

Enabling Part 2 Content

In your dedicatedserver.cfg, add the Part 2 flag to load expansion content:

{
  "Difficulty": "Normal",
  "SaveSlot": "Multiplayer",
  "IsPublic": true,
  "RegionInfo": "",
  "LanServerPort": 8766,
  "GamePort": 27016,
  "EnablePart2": true,
  "SecondCubeEnabled": true,
  "BunkerCityDepth": 5
}

The Second Cube: Co-Op Locking

The Second Cube ending is designed for coordinated groups. Server admins can lock the Cube ending behind a minimum active player count:

# In ServerSettings.ini
[Part2]
SecondCubeMinPlayers=4
CubeRoomLockOnSingle=true

Expanded Bunker-City Performance

The new underground network introduces complex multi-floor environments with particle-heavy trap systems. Monitor your server's thread utilisation — Part 2's lighting calculations are substantially heavier than the surface biomes. Reduce MutantSpawnRate in Bunker zones by 20% if you notice consistent FPS drops during underground exploration.

Save Compatibility: Part 2 saves are NOT backwards compatible with Part 1. Once a server enables Part 2, rolling back the update will render the world unloadable. Double-check your backup strategy before flipping the switch.

Professional Hosting
