Darn, I can't edit. I'm thinking there were about 4 Secret Locations in all - Vlad (which granted, not everyone has access to yet), Maidan's Tower and Haggia Sofia (sorry if I mangled that), and I'm thinking another one that I can't remember off the top of my head. So perhaps only two of them were integrated into the story, and two were optional. A little lighter then the others games, yet, but it's not correct to say they weren't in the game at all.
