So, you have found Project-GC's Adventure lab cache. Nice work! This Adventure Lab has five (5) locations that you can find. They are all spread out on the website Project-GC.com. To be able to see them, you must first have visited https://project-gc.com/Home/PGC-AdventureLab in the last 24 hours. If you found the code (or QR) to this Adventure at Project-GC, it's likely that you found it on mentioned page, and that you then have 24 hours from that to find the clues. If you didn't manage to find them in those 24 hours, just visit the page again to enable the clues for another 24 hours. Good luck!
