A multiplayer hacking simulator with a graphical OS, built in C++ and OpenGL.

Dependencies

The following dependencies are required:

• A C++ compiler (e.g., clang, g++)
• CMake (3.16 or newer)
• SDL3 development libraries
• SDL3_net development libraries
• GLEW development libraries
• FreeType development libraries

Installation (Debian)

You can install most required dependencies with the following command:

sudo apt update
sudo apt install build-essential clang cmake libsdl3-dev libglew-dev libfreetype-dev

Installing SDL3_net (from source)

As SDL3 is new, the networking library may require compiling and installed manually.

1 Clone the repository:

git clone https://github.com/libsdl-org/SDL_net.git
cd SDL_net

2 Build and install:

mkdir build && cd build
cmake ..
make
sudo make install
# You can delete the downloaded SDL_net directory after install.

3 Update linker cache: If you have linker issues after install SDL3_net, try updating your linker cache.

sudo ldconfig

Build Instructions

This project uses a top-level Makefile to simplify the CMake workflow. Build artifacts will be placed in the bin/ directory.

Simply run the following commands from the root of the project directory:

• Build the project:

  make

• Build and run the client:

  make runc

• Build and run the server:

  make runs

• Clean the project: This removes the bin/ directory.

  make clean

Project Structure

The codebase is organised into three main components:

• common/: A shared library (libbettola) containing code used by both the client and server.
• client/: The game client (bettolac), handles rendering, UI, and user input.
• server/: The game server (bettolas) manages game state and the world simulation.

Planned Features

Note: [X] indicates a feature that is currently in progress.

Core Gameplay & Hacking

• Custom-built graphical OS desktop environment.
• Interactive terminal with command history and scrolling.
• Draggable and focusable UI windows.
• Local and remote virtual file systems (VFS).
• Core filesystem commands (ls, cd).
• Remote system connections via ingame ssh tool.
• Network scanning tools to discover hosts, open ports, and running services.
• A deep exploit system based on service versions (e.g., SSH, FTP, HTTP).
• Ability to find, modify, and write new exploits.
• Functionality to upload/download files to and from remote systems.
• Log cleaning utilities and other tools for covering your tracks.
• Social engineering through in-game email and websites.

The World

• Narrative-driven main storyline (serves as tutorial before the sandbox world).
• Emergent gameplay arising from the interaction of world systems.
• A persistent, shared "core" universe of high-level NPC networks.
• A unique, procedurally generated "local neighbourhood" for each new player.
• NPC factions and corporations with simulated goals and stock markets.
• Dynamic missions generated organically from the state of the world.
• Active NPC system administrators who patch vulnerabilities and hunt for intruders.

Player Systems & Progression

• Embedded Lua scripting engine for creating custom tools.
• In-game code editor with syntax highlighting etc.
• Secure, sandboxed execution of player scripts with CPU/RAM as a resource.
• An in-game internet with a web browser, email, and online banking.
• Online stores for purchasing virtual hardware, software, and exploits.
• The ability to purchase and upgrade dedicated servers.
• Hosting of player-owned services (web, FTP, etc.).
• Creation of custom websites using HTML and basic JS.
• Player-to-player secure messaging and file transfers.
