If you realize you have two return ,

 @Override
        public boolean onCreateOptionsMenu(Menu menu) {
        return super.onCreateOptionsMenu(menu); //primer return.
        MenuInflater inflater = getMenuInflater();//Aqui se lanza el error Unreachable Statement
        inflater.inflate(R.menu.game_menu,menu);
        return true; //segundo return.
     }

the first one will cause you to have a null menu since it does not inflate the menu at any time:

 return super.onCreateOptionsMenu(menu);

You can simply return true , after the inflater, "inflates" the layout using the inflate() method:

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.game_menu, menu);
    return true;
}

MenuInflater Instance the .xml of the menu in objects Menu .

This is how the function onCreateOptionsMenu() should be.

public boolean onCreateOptionsMenu(Menu menu) {  
    MenuInflater inflater = getMenuInflater();   
    inflater.inflate(R.menu.game_menu,menu);  
    return super.onCreateOptionsMenu(menu);  
}
