I got injustice ultimate edition the other day on the PSN. The game finished downloading fine. When I booted it up I was met with a message saying that not all the characters and content had finished downloading but I was still able to play single fight mode. After a few fights all the characters and the STAR labs opened up but, the other 2 modes were still locked.
Now my internet is not fast so is it just a matter of me having to wait for some invisible download to finish to get the other content? If so does the game itself have to be running for this to take place?
