Hello Maksim Khegai, 

I have a question about story mode. Is it possible to create a story-driven first-person shooter (FPS)? This is my first time using it, and I don't have any experience, but I really admire your work. I would like to know if I can implement a story. 

Of course, I can practice and learn something for good.

Yes. I recommend you refer to the manual, you'll learn everything you can do there.
