KK all you have to do for this one is pretty much be horde (its easyier) ok fly to Hammer fall (this is on you tube) go behind hammer fall and go in the red portal thing then u will just walk into it like a wall...(that's imba but thats not it)

right then use the auto unstuck key next to it and walk thru the cave to the end.



yet again theirs another invisible wall . then log out and w8 till u can do auto unstuck again dunno if you can do it instantly again i had my tea while i waited anyhow.
then log back in and use unstuck feature again through it and go to the end of the cave and welcome to AB. im not sure if theirs players tho .. . +1 if good.
