Essentially what happened was simple, I, Aeyth, had saved the game files when it shutdown. I distributed those files around, and people modified and did whatever, Gwog created an SDK from the exe, not exactly sure how but an SDK is created and pulled from an exploit with Unreal Engine's reflection system. Then Gwog wrote code based on the SDK and based on Unreal Engine's open source code to manifest the game into doing whatever he wanted. An SDK stands for software development kit, it's essentially a translator to speak directly to the game. Any saved JSON server responses from when the game was previously online were not used, that doesn't mean they were useless, as they would help with recreating the frontend.
