Spike enemies to the wall or reel them in with this automatic harpoon gun.

The Harpak is a IconGrineerOn.png Grineer harpoon gun standard issue for Drekar Elite Lancers. It has two firing modes; its primary firing mode fires a burst of three harpoon projectiles, while its Alternate Fire fires a chain-tethered harpoon that will damage foes and pull most targets towards the user.


  • This weapon deals primarily DmgPunctureSmall64.png Puncture damage.
  • Primary fire shoots three harpoons in a burst.
    • Bolts fired stick to their target, and will fling bodies on kill.
    • The body will damage targets in its path.
    • Flung bodies help in dealing with crowds.
    • Corpses can be pinned to terrain.
  • Alternate Fire shoots a harpoon that inflicts a guaranteed DmgPunctureSmall64.png Puncture proc and can reel enemies in close and knock them down.
    • Can '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.
    • Knockdown leaves target open for melee finishers.
  • Can use the Harpak-exclusive Mod TT 20px.png Exposing Harpoon mod.

  • Enemies can be pulled into bottomless pits or inaccessible areas, killing them instantly.
  • The Harpak's secondary fire mode (default Mouse 3 ) fires a tethered harpoon that can pull enemies towards the player and causes a guaranteed DmgPunctureSmall64.png Puncture proc. The harpoon costs 1 ammo to fire.
    • The secondary fire mode has a maximum range of 50 meters, projectile flight speed modifiers (Riven Mods) and mods like Mod TT 20px.png Terminal 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 20px.png Terminal 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)
  • Enemies killed via the secondary fire, are pulled 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 Paracyst.png 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 G.svgGrineer R.svgGrineer I.svgGrineer N.svgGrineer E.svgGrineer E.svgGrineer R.svg, 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 DmgPunctureSmall64.png Puncture damage. Another example of this is the Nukor.png 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 DmgImpactSmall64.png 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.
