Interesting theory there could possibly be another step to tranzit, or there possibly Isn't If there Is another step props to treyarch but It doesn't make sense to have quotes that nobody has heard before and these might also be quotes that were added In the game as steps for the original version of the tranzit EE because lets be honest treyarch probably kept changing their mind on what they want the player to do and they just left the audio In and somebody extracted the audio

nice video explained well, going a few months back i did believe there was more to it, but now im thinking surely not unless everyone of us is missing something?
