Most epic battle ever! Enclave lands in vertibird over the hill comes outcasts and to top it all of f, 4 albinos outa nowhere. Now tell me thats not epic! Ahhhh the good ol' days.
What you have to do is:
Their a tree in the centre of a ditch near the outcast camp just near Fort Independence.
Its a random encounter place where a Verti-bird lands and then a outcast patrol will probaly come over the hill.
Its completely random that a albino will apear, 4 of them is about 4 in a million chance of happening.
