# Project Overview

Commonwealth Online is a prototype multiplayer framework experiment for Fallout 4.

The first target is not full co-op. The first target is a controlled test where two clients can connect to a local server and see each other as synced actors in a custom test cell.

## Core Idea

Fallout 4 remains the client application. A native F4SE plugin reads local player state and communicates with an external server.

The server tracks connected players and broadcasts relevant state to other clients.

A Creation Kit plugin provides test cells, placeholder actors, scripts, and controlled test content.

## Basic Flow

```text
Fallout 4 Client A
        |
        | local player transform
        v
External Server
        |
        | remote player transform
        v
Fallout 4 Client B
```

## Early Limitations

The first prototype should assume:

- All players are in the same cell
- No quest synchronization
- No settlement synchronization
- No VATS
- No dialogue sync
- No full inventory sync
- No support for large modlists
