This weapon deals primarily Puncture b Puncture damage.


  • Primary fire shoots three harpoons in a burst.
  • Alternate Fire shoots a harpoon that inflicts a guaranteed Puncture b Puncture proc and can reel enemies in close and knock them down, leaving them open for melee finishers.
    • High Puncture b Puncture damage and Impact b Impact damage – effective against armor and shields.
    • Pinpoint accuracy.
    • Can also 'pull' humanoid flyers (such as Hellions) down, and pull enemies that are stunned by Warframe powers.
    • The harpoon pull can interrupt enemy casting/power animations, including the charge-up for Railgun MOAs.
    • Enemies can be pulled into bottomless pits or inaccessible areas, killing them instantly.
  • High critical chance.
  • Above average critical multiplier.
  • Good status chance.
  • Fast projectile speed.
  • On kill with primary fire, bodies will follow the harpoon that killed them, damaging anyone in their path and pinning the corpse to walls.
  • Can use the Harpak-exclusive Exposing Harpoon mod.
  • Innate Madurai Pol polarity.


  • Primary Fire:
  • Low Impact b Impact and Slash b Slash damage – less effective against shields and health.
    • Linearly less efficient – sometimes a target may only die with 4 bullets, which requires an entire second burst to be fired.
  • Alternate Fire:
    • Low Slash b Slash damage – less effective against health.
    • Projectile has arcing.
  • Projectiles have travel time.


  • The Harpak's secondary fire mode (default Mouse 3 ) fires a tethered harpoon that can pull enemies towards the player and causes a guaranteed Puncture b Puncture proc. The harpoon costs 1 ammo to fire and also requires a short charging time to be completed before it can be fired.
    • The secondary fire mode has a maximum range of 50 meters, projectile flight speed modifiers (Riven Mods) and mods like Mod TT 20pxTerminal Velocity will increase this range. While the harpoon will still hit enemies up to its maximum range, it will only pull them if they are at a distance smaller or equal to 40 meters, projectile flight speed modifiers (Riven Mods) or Mod TT 20pxTerminal Velocity do not increase this range.
    • It seems that the harpoon is unable to break Resource Deposits (yet it works just fine on explosive barrels and Storage Containers, more testing required)
  • The Harpak ragdolls enemies it kills a significant distance with momentum. This momentum allows the Harpak to kill an enemy behind the first target by sheer force.
  • The Harpak's firing noise increases in pitch as the magazine depletes.
  • Mechanically, the Harpak is nearly identical to the previously introduced InfQuantaRifle Paracyst, as both rifles are burst-fire projectile weapons that shoot out pulling harpoons as their secondary fire mode.


  • The Harpak's name is derived from Harpoon, a long spear-like instrument used in fishing, whaling, sealing, and other marine hunting.
    • It might also be influenced by the Harpax, a device which was intended to launch harpoons into naval vessels and reel them in for boarding, similar to the Harpak's alternate fire.
  • The Harpak was first presented in the Update 17 Teaser Site, but its name was not revealed until the release of the Echoes of the Sentients Highlight Video.
  • The word in Grineer found by the barrel of the weapon, Grineer GGrineer RGrineer IGrineer NGrineer EGrineer EGrineer R, spells out Grineer.
  • It is one of the few Grineer weapons in the game that can be used against them effectively, as it mostly deals Puncture b Puncture damage. Another example of this is the GrineerMicrowaveGun Nukor.
  • Oddly, the Harpak's alternate fire can be seen ricocheting from enemies when they are already under the effects of crowd control such as an Impact b Impact Proc and will harmlessly float in the air away from the target for a few seconds.


  • Unlike previous projectile weapons, the Harpak's bolts will not share the same color as the ones selected for both its primary and secondary attack.
  • In the ballroom simulacrum room, using the harpak on an enemy close to the statues will result in their body turning ragdoll and suddenly dying should they touch either of them.
