Forum:Black Ops II Prologue

How come the prologue never comes up for me anymore when I play Black Ops II? You know, the opening movie. I only got it the once.

Same with Black Ops 1, but I do get that every now and then.

I kind of like it, and want to watch it every now and then when I start up the game. Does anyone know how to get it back?
