Today Chris Roberts' Cloud Imperium Games released a new video of its upcoming space simulation Star Citizen.

The video focuses on the short and long-term goals for atmospheric flight, aiming to make flying close to the surface of a planet feel completely different from flying in space.

On top of that, we also get a small tease about the single-player campaign Squadron 42 sent in a newsletter to backers. A screenshot features an Avenger spaceship bearing the "Advocacy" livery with a destroyed space station on the background. Advocacy is a sort of police force with jurisdiction over interplanetary crimes and cases that extend into alien territory. This is certainly interesting, considering that Squadron 42 is mostly a military story, and we'll have to see how Advocacy fits into it.

On December 20th, Cloud Imperium Games will publish a teaser featuring Mark Hamill (who plays a major role in Squadron 42), and the next video of this series will focus on the single-player campaign, hopefully providing a release date or window. It'll come on December 21st.

In more Star Citizen news, Crytek has opened a lawsuit against Cloud Imperium Games, seeking damages for alleged copyright infringement and breach of contract over the use of CryEngine 3.0. CIG, that has switched to Amazon's Lumberyard spin-off a while ago, defined the lawsuit "meritless," and promised to defend "vigorously" against it, including recovering any legal expense incurred from Crytek.
