Try the Demo Map

The fastest way to see Operating System Simulator in action is to open the bundled DemoMap before building your own device from scratch.

    direction LR
    CB["Content Browser"] --> Map["DemoMap"] --> PIE["Play In Editor"]
  end
  subgraph row2[" "]
    direction LR
    BIOS["UOperatingSystemBIOS boot"] --> Desktop["UOperatingSystemWidget desktop + programs"]
  end
  PIE --> BIOS

Open DemoMap

1. Complete Prerequisites — enable Show Plugin Content.

2. In the Content Browser, navigate to:

   Plugins → OperatingSystemSimulator → OperatingSystemContent → Demo → Maps

3. Open the map and press Play.

You should see a device boot through BIOS, install or load an OS, and present a full desktop with Explorer, Terminal, Store, and other bundled programs.

What to try in PIE

Action	What it demonstrates
Open Terminal	Built-in commands; some broadcast Global Messenger events
Browse Explorer	Simulated filesystem with directories and file types
Open Store	Install optional programs at runtime
Change Settings	Theme and wallpaper modules
Shut down / restart	Device state machine on UOperatingSystemBaseDevice

Standalone demo game

A packaged Windows/Mac demo is also available — useful for sharing with teammates who do not have Unreal installed.

Starter template project

Download the starter template from the Demo page if you want a pre-wired project instead of adding the plugin to an empty game.
