Release date[]

  • South Korea: 19 October 2017.
  • Taiwan/Hong Kong: 24 October 2017.

  • The Energy Storage System can hold up to 8 bars of energy and it takes 3 seconds to fill each bar. It charges regardless of if you're holding it or not. A full reload will consume 6 bars.
  • It can chain 8 enemies up to 4 meters away from you, and up to 3 meters away from your first target.
  • The damage of the lightning scales with the amount of ammo remaining in the magazine prior to reload. At 29, it has 200 base damage. At 0, 500.
  • Not recommended to use the electrical attack in normal matches since it deals a very low damage and doesn't affect the enemy movement.

Zombie Hero[]

  • This is best used in combination with a high-damage melee weapon such as Dual Sword Phantom Slayer. It can be used easily to stop zombies in their tracks and line up for the killing blow.
  • Its bullets have base damage on par with AUG Guardian, but don't penetrate armor very well.
  • The Energy Storage System ensures you to never be caught out while reloading it. However, it does stun the enemy. Be sure to always keep distance with zombies.
  • Pay attention to how much energy remains when you're attacking the zombies. Use it wisely since the energy can easily run dry and need a quite long time to charge up.
    • When the magazine is empty and the electrical energy is available, switch into a secondary or a melee weapon to keep the energy. When the enemy approaches, switch back.

Zombie Scenario[]

  • Not recommended to use for Hard levels due to its poor damage and lack of competency.
    • In Normal or Easy difficulties, this weapon is useful when surrounded by a horde of zombies.
  • The bullet does 75 damage per shot to barriers and 500-800 to bosses. The electrical attack can't be triggered by barriers but deals 1,000 damage per second to bosses.
  • In Easy 1 and 2 difficulties, it can be a good weapon of choice due to the lightning's zombie-clearing potential, but often loses out to weapons with splash damage.


Shoot sound

Ditto, during the reloading


  • The weapon model is based on the Daewoo K1A while the lightning mechanism is based on the JANUS-7. The lightning is stronger if reloaded when the ammo is zero, which reuses the mechanism from VULCANUS-3.
  • There are three different idle animations: no energy, charging energy, and full energy.
  • The maximum range of the electrical attack is 7 meters.
