Weapon pools in Destiny 2 change over time, and players saw some of the armaments in the game come and go in recent years. It’s the case for Silicon Neuroma—the gun would drop from The Pyramidion Nightfall on Io but disappeared after its Power Level was capped and after Io was removed from the game with Beyond Light.
For The Witch Queen, though, Silicon Neuroma is once again back in the loot pool, and it has a couple of tricks up its sleeve. The perk pool on Silicon Neuroma can definitely make it worth the grind, and this 72rpm sniper could end up as a favorite to take on the Kinetic slot.
