This looks an awful lots like a teaser for a new Star Wars movie, but no. Star Wars Eclipse is a video game in development from the French company Quantic Dream. It was revealed at the Game Awards 2021 yesterday. Honestly, you should see it in theater mode, or even just the wide-screen version at YouTube.
The game is set in the era of the High Republic. You control multiple characters, each with their own motives and morality. Learn more about the game at its website. There you can sign up for email updates, download a fan kit, and see more stills. Unfortunately, since the game is still in development, there's no launch date as of yet.
