The world of Borderlands 2 is full of secrets. If you’ve been playing the game for awhile, you may have noticed a few QR codes scattered throughout Sanctuary and in other parts of the game. Holly Green has taken the initiative to document the locations of each of these QR codes and what they mean.
The most ubiquitous QR code in the game can be found on any Moxxi’s pizza box, as seen below:
It reads: “Wise man say, forgiveness is divine but never pay full price for late pizza. -Captain Picard”
There are several postcards in the Crimson Raiders HQ stamped with QR codes. They are postcard invitations that appear during the mission “Claptrap’s Birthday Bash”. A few of them can be found scattered throughout Sanctuary, no doubt serving as a reminder of Claptrap’s spectacularly bad birthday party later on in the game.
It reads: "NICK WILSON
HO OH"
Finally, the last QR code can be found in a locker inside of Dr. Ned's office. It only appears in True Vault Hunter Mode.
It reads: "Thank you so much for playing our game, now I'm rich with love AND money! !!Nick Wilson!! Ditto!!! "
