when trying to connect, or is the server just not appearing in the list?

Step 1 – Set Steam to Offline Mode

• On all PCs, open Steam → Go Offline (Steam menu → Go Offline… → Restart in Offline Mode)

Issue: Players appear in lobby but can’t start game

• Fix: Each player must have a unique force_steamid.txt. Duplicate IDs cause desync.
• Fix: Disable Hamachi or any virtual network adapters. Use pure Ethernet or Wifi.

Step 2 – Launch the dedicated server

• Run DedicatedServerLauncher.exe
• Under Game Mode → choose Cooperative or Deathmatch
• Network → set to LAN
• Server Name – choose something obvious
• Max Players – set as needed
• Click Start Server

Step 3: The Steam Emulator (The "Hot" Trick)

You need a lightweight Steam emulator. Note: Do not download shady .exe files. Use Goldberg Emulator or SmartSteamEmu (SSE) – these are open-source tools.

Simplest approach (using SSE):

1. Download SmartSteamEmu (version 1.4.3 or newer).
2. Extract the contents into your Serious Sam 3 root folder (where Bin folder lives).
3. Run SmartSteamLoader.exe instead of Sam3.exe.
4. The emulator will generate a fake steam_api.dll and steam_appid.txt. Inside that .txt file, put the App ID for Serious Sam 3: 41070.

If you don't want an emulator: Rename or delete steam_api.dll in the Bin folder. The game will fall back to a LAN-only mode (works on version 1.0 only).
