MineMogul Multiplayer

Mine Mogul Multiplayer adds Steam-based cooperative multiplayer to Mine Mogul, letting up to 4 players mine, build, and manage a mogul empire together in real-time. One player hosts a session and invites friends through Steam — the entire world stays in sync including buildings, machines, conveyors, ores, economy, research, and quests.

This mod is in active development and should be considered an early release. Expect bugs, especially with physics-heavy scenarios (lots of loose ore pieces, conveyor systems, etc.). The mod includes built-in tools to help recover from sync issues — see the tips section below.

This mod does not currently support any other BepInEx mods. Running additional mods alongside it may cause conflicts, crashes, or desync issues. Use at your own risk if combining with other mods.

INSTALLATION

• []Download the main file (MineMogulMultiplayer-v.zip)[/]

  []Navigate to your Mine Mogul game folder (usually: C:\Program Files (x86)\Steam\steamapps\common\MineMogul)[/]

  []Extract the ZIP contents (BepInEx, .dll, config) directly into the game folder — it will place files in the correct locations automatically[/]

  []Launch the game — you should see a "Multiplayer" button on the main menu and pause menu and hosting options when loading or starting a new save.[/]

  []Full world synchronization — buildings, machines, conveyors, ore pieces, economy, research, quests, and more[/]

  []See other players with animated tools, crouching, and held objects[/]

  []Lobby system with Steam friend invites[/]

  []Mid-game join — invite friends at any time, even during active gameplay (the game will save and reload to sync the new player)[/]

TIPS & KNOWN ISSUES

This mod is still in development. Here are some important things to know:

• []Physics desync is the most common issue. If ore pieces or crates appear to be in the wrong place or jittering, the host should clear loose physics objects from the ground. Fewer loose ores = better sync performance.[/]

  []Use Force Resync. Open the multiplayer panel (F9 or via the pause menu) and click "Force Resync" to make the host re-send the full world state to all clients. This fixes most visual desync issues.[/]

  []Only the host can save. Client saving is intentionally blocked to prevent save corruption. The host's save file is the authoritative copy.[/]

  []The game does not pause in multiplayer. Opening the pause menu will not freeze time for other players.[/]

  []Mid-game joins trigger a brief reload. When a new player joins during gameplay, the host's game will save and reload to give the new player a clean state. This is normal.[/]

  []F10 toggles a stats overlay showing network info, tick rate, and sync status — useful for diagnosing issues.[/]

  []If the game crashes on startup, make sure you haven't replaced the included BepInEx files with a different version. Only the bundled BepInEx 6 build works with Mine Mogul.[/]
