Crytek has filed a suit against Cloud Imperium Games (developers of Star Citizen and Squadron 42) for wrongdoings regarding Crytek's CryEngine. Cloud Imperium Games has recently moved over to Amazon's Lumberyard, a free, cross-platform triple-A game engine which has been built-upon by Amazon, based and licensed from Crytek's CryEngine in 2015. Apparently, in doing so, Cloud Imperium Games has violated a number of agreed-upon items on their engine licensing contract, for which Crytek is now going after for damages and compensation.

The essence of the suit stands in that Crytek only licenced its engine for the development of a single game - Star Citizen - and that CIG is now developing a second one in Squadron 42, for which it had no rights to use Crytek's IP and assets. Futhermore, CIG agreed, when signing the contract, to use Crytek's logos as part of the game development and final game presentation, so as to provide awareness for the company, but has since removed them from all instances of the game.
