Supersonic Flag

Watch an advertising video and you will be awarded a Supersonic Flag. This flag will boost passenger regeneration +15% compared to the normal 10% of a standard Flag. You can access the video by clicking the extra tab in the upper left coner of the screen next to your passenger count. You need to watch the full video in the video player that appears on the game screen. Once complete, a green bar will appear at the top of the player informing you that the Supersonic Flag has been placed in your station.

If you click the ad video and go to the linked page to watch the video, you will not get credit. The video must be watched on the game screen player.
