Unlocking Club Competition

[Trillian]

I managed to accidentally unlock club competition armor pieces.

%90 sure it was from doing the co-op missions in Dead Kings DLC, but I also was part of a club for about a week so that might have done it too.

TL;DR - To unlock club competition

1. Join a club.
2. Do the Dead Kings DLC (all of it, including the 2 co-op missions.)
3. If it doesn't work, wait a week and check back.
