*IMPORTANT* If the game crashes to the disclaimer screen when you start it, try deleting your old save files located at "USER/AppData/Local/DoublePlayer"; you will find a folder named "Save" there—delete it entirely. (I am still investigating the cause of this issue.) This should resolve the problem; however, if you encounter a different issue, please leave a comment on the project page—this helps me improve the project.
It works, thanks. I had another problem, that I've solve by myself. It called Unreal "fuck it" engine. It runs game at maximum preference, and at start of a game a had a slideshow. And just lower settings caused the game to crash. In the end, I had to lower and save each setting separately. It should make sure the game doesn’t launch at maximum settings on the first run.
