Quantum Spook is an augment. When obtained, the player's attacks will be able to phase through walls and shields, affecting both primary weapons and Powers.

It can be found as a drop from Gold Chests. It can also be found in Shops with a price of 35 Nuts.


  • Splinterfrost synergises poorly with the augment, as it loses its ability to shatter upon hitting a wall.
  • The effect is less useful with Wave Beam, which already has the ability to attack through walls, but not shields.
  • Mortar and Rapture become a lot easier to aim when you don't have to worry about hitting the ceiling when arcing your shots.
  • Quint Laser becomes considerably easier to use, as you no longer have to worry about the projectile hitting platforms or Agnisort's ceiling.


  • Wildfire is completely unaffected by the augment, as it would render the Power almost completely useless otherwise.
  • The image for Quantum Spook bears a resemblance to the scouters used by various characters in Dragon Ball Z.
