The Amprex rifle fires a continuous beam of high voltage electricity that arcs among nearby enemies. This weapon excels at crowd control.

The Amprex is a Corpus rifle that is unlockable through the Energy Lab in the Dojo after researching the CorpusEnergyRifle Dera. The Amprex can damage large crowds of enemies by firing multiple Electricity b Electricity arcs that can chain between units.

This weapon can be sold for Credits647,500.

Weapon LoadoutsEdit

NotesEdit

  • Resource-heavy to craft, requiring Fieldron648 Fieldron and ArgonCrystal643 Argon Crystals, as well as Ferrite64 9000 Ferrite.
  • The Amprex fires a single beam of electricity which then chains to nearby enemies.
    • The beam will chain to the closest living enemy in range dealing half damage to it. From there it will chain additional times (3 to 4 times total), halving the damage each time.
    • Headshotting the original target does not affect damage from chain lighting.
    • Chain lightning will also be emitted if an enemies corpse is chosen as the original target.
    • Additional electrical arcs are also emitted, striking randomly around the player. However, these stray arcs are purely visual in effect.

TriviaEdit

  • After the clan obtains the Energy Lab, it will take exactly 12 days to research this weapon.
  • The Amprex's name is a portmanteau of the words Ampere (the base unit of the International System of Units used to quantify electric current) and the word Rex, which is the Latin word for king.
    • The word ampere itself is named after a French mathematician and physicist, André-Marie Ampère, who's also considered to be one of the fathers of classical electromagnetism, most commonly known for Ampère's Circuital Law.
    • Like the CorpusLaserRifle Flux Rifle and DECorpusHandCannon Detron, Amprex does not conform to the common Corpus weapon name scheme; two syllables ending in 'a'.
  • The weapon shares its similarities on its battery components with DETetra Tetra.
  • This is the third Primary weapon that deals purely Electricity b Electricity damage, after the CorpusSniperRifle Lanka, and U10InfPrimary Synapse.
  • This is the second clan weapon that does not need a Forma in its construction.
  • Hatches on the side of the Amprex slowly open up during firing, spreading vanes underneath. This animation is a visual indicator of the weapon's magazine capacity, with the vanes spreading out more the closer the magazine is to empty. The hatch closes upon reloading.
  • This is the first weapon in Energy Lab whose duplication costs 50,000 credits.
  • After Update 15.13, the chained beams were changed to be affected by Mod TT 20pxSinister Reach as well. As of Update 22.14, this is no longer the case.
