When I was playing with my Zero character, the game crashed.
And then came Error 999, I tried several times to play the game but Error 999 still came.
Once, I clicked Play and Error 20010 came. I thought the problem was my wifi, so I turned it off and switched it back on.
The only thing that's changed is that I get error 999 instead of 20010

    This Reddit thread suggests that Error Code 999 is a Steam launching error, and waiting it out may be the only option.
