Make sure you've played all the games (except part III (coming soon)) in this studio before playing this: https://scratch.mit.edu/studios/5858590/ Whenever there's dialogue, the color of the text is the same as the color of who's speaking. Gray text is instructions. If it gives you a "Part III Coming Soon" screen when you start, restart the project.
In Part II of the series, a soldier (controlled by you) goes searching for the Device, stolen by a mysterious entity via mind-controlling an innocent square. Music is Force by Alan Walker.
