Faceware already laid out the process of their involvement and none of it involved source code from CIG or crytek. They made an api. Cig implemented it into their version of the engine and the. Requested tweaks and features. Crytek have not listed any episodes or lines of code, yet, that broke copyright so I doubt any have been taken down. Do the episodes have actual cryengine source code in it or star engine code that’s been written by CIG and how do you know the difference?
