The basic premise for this one is that the Unification Point is approaching, and the GUARDIANS need to protect the photon generators that could send the SEED on a one way trip to another dimension, saving Gurhal once and for all. Like most things in PSU it boils down to killing monsters. Lots of monsters.
Like Operation: Firebreak and Maximum Attack G, Shred the Darkness keeps a tally of how many monsters have been defeated on its website; We unlock rewards as we reach the predetermined milestones. As you can see from the image at the top there, it runs for a massive five weeks – that’s longer than the Japanese version of this event. Hopefully we can fully unlock all the rewards.
