Portrait SN-Z.png


SN-Z is a T10 Event Boss found within its own unique dungeon, the Iron Lair.

Unlike most bosses, SN-Z is constantly moving in one direction, making engaging SN-Z with a single-stick plane significantly easier compared to other bosses. SN-Z alternates between spawning converging shots, firing rear-facing projectiles, and throwing out AOE mines. At about half health, SN-Z will also spawn Robo Squadrons along with its converging shots.

  • Percentages aren't always exact. Some are based on patterns. Some are even just estimates.
  • Values shown are "chance for this item to drop on any given kill" with one exception:
    • Where "one of many" can drop (e.g. T10s, ELEM weapons), they all show the total chance that any of them will drop.
