Forgive me for me English, but I hope it will be clear:
The fact is that the copyright holder does not close projects at all. (Close only fan remastered and
remake, After all, there is also copyright to other people 's work) He sends out demands to remove the references.
I am sure that copyright holders know about the project
I sent information and many times wrote letters about the game to copyright holders - silent. No answer.
In fact, in the worst case, it means to Alien model and remove the names and symbols of WY, because 100% of the right holder for all source code and models to the game is me.
So the game is going forward at a great pace and nothing threatens it. With your support, the game will go faster.
