Preview: logging in needs the MSP Web Connector extension.

Log in with the MSP Web Connector

Logging in and playing need a small browser extension, the MSP Web Connector (Chrome, Edge, Brave, Opera). It connects the game to MovieStarPlanet from your own browser and connection.

Have it? Click its icon in the browser's toolbar (under the puzzle-piece icon if it is not pinned). The game carries on from where you are.

Don't have it yet?
  1. Download msp-web-connector.zip and unzip it.
  2. Open chrome://extensions (Edge: edge://extensions), switch on Developer mode, click Load unpacked and pick the unzipped folder.
  3. Come back to this page and click the extension's icon, or reload the page.
