8 Video Game Mysteries Developers Had To Solve

8. The Niobe Labs Puzzle - Destiny 2

In early 2019, Bungie released the Niobe Labs for Destiny 2 - the game's most complex puzzle up to that point, so tricky in fact that even the series' most die-hard fans couldn't figure out how the hell to solve it and unlock the fourth Black Armory forge, Bergusia.

The labs required players to solve a seven-part series of arcane ciphers while battling progressively tougher waves of enemies, but eventually fireteams found themselves desperately unable to progress any further.

With the challenge taking longer than expected, Bungie ended up voluntarily releasing Bergusia to the player-base, all while players continued plugging away at solving the labs in earnest.

After more than three days of failed efforts, however, Bungie finally revealed that the Niobe Labs were actually bugged, and that a gameplay element was accidentally removed which would've given players an indication of what to do next.

And so, the devs dropped an epic hint in their post, which in turn allowed players to finally beat the final section of the labs barely 30 minutes later.

All in all, it took 81 hours for a single fireteam to complete the Niobe Labs after they were released, but it would've been much sooner if Bungie hadn't done a major behind-the-scenes whoopsie.
