You see, I did the easter egg in buried BO2 and when I got to round infinity, I found a broken untouched fusion outline. Then I had to go back in time to the destiny beta time and find the orb of darkness. After that, I had to go to the future over to destiny 3 and get the long lost note of space and time, it read, [quote]Find the truth of time travel itself and realise that you have already done it. Go back and find the speakers cousin, he will give you the weapon core. Bring it to the gunsmith to claim your prize.[/quote] Then I did all of that and got the vex. Yeah!
