>25. On February 14, 2016, Defendants moved forward with their plan for Squadron 42 notwithstanding their failure to obtain a license and began offering the video game for separate purchase. As a result, Defendants are intentionally and willfully using CryEngine without a license and in violation of copyright laws.
This seems to be the main point. They're claiming Star Citizen is using CryEngine for their new game, and haven't licensed it out to do that, along with the company behind Star Citizen distributing assets of Cryengine in various ways. They were also supposed to help in developement of Cryengine in way of bug fixes, and did not comply.
Crytek's GLA appears to be pretty far reaching.
>38. On December 23, 2016, Defendants announced that they were using the Amazon Lumberyard video game engine for Star Citizen. The GLA did not permit Defendants to use any other video game engine in Star Citizen except for CryEngine.
>50. On May 6, 2015, Defendants began posting a series of videos online titled "Bugsmashers." The videos contain excerpts of information from CryEngine that were confidential, in breach of the GLA, and should not have been shown to the public. The series continues today.
