A secret buried within Battlefield 4's newest map is so byzantine in its solution, it's something of a wonder players uncovered it at all. But YouTube video creator Jackfrags — with some help from others in the community — did, which he details in a new video.

Last week, developer DICE released a new Legacy Operations map, Dragon Valley (which originally appeared in Battlefield 2), for Battlefield 4. Hidden within that map are a series of switches, which trigger a series of lights, which flash in sequences of Morse code, which lead to riddles, which lead to other maps with their own secrets. Suffice it to say, it's a complicated sequence of events, and considering that there's no universal solution, you'll have to decide whether the payoff — a formerly DICE employee-exclusive camouflage pattern — is worth it.

Still, it's something of a marvel that the community sorted out the solution in a week's time. You can watch Battlefield 4's latest mystery unraveled in the 11-minute how-to video from Jackfrags above.
