So I've re watched the first ever black ops reveal trailer. It shown a guy (presumably a soldier.) used as a test subject. The dialog you hear is a probably a Scientist in the background observing his "reaction". Seeing as the Scientists said "this will help you remember everything" and "giving you something extra to assist you". Not to mention the part where the Scientist says "Once he regains consciousness double the voltage." Then he seems to flat-line. And they said that they "need to bring him back."
So any ties between this reveal trailer, GKNOVA, and possibly zombies?
