The challenge is to place top 30 in duos with only a backpack armor and a helmet two times I have done this many times but don't even have 1/2 anyone else having this issue?
This is going to sound silly - I was having trouble too - until I got it this way It worked for me - yes get the helmet - armour- backpack - then don't die because your armour is shot off. I ended up killing myself with crossbow when in top 30 - which doesn't touch armour - voila - it worked !
