nah that the end of that version, when you done other task with other girl the credit scene will appear to wait next update. in my case its was when kate confess and walaa like the end of movie lucky me.
I don't know, I got the version that later they said was the one with a problem and as I had already played it I just continued, but it got confused when I tried to use the guide, I stopped at the part where I got Mako with the Thing in the underground training room and I have to call the guy who gave me the card at the beginning of the game. Do you know anything about this?
