An ancient weapon designed by the Entrati. Primary fire siphons life essence from the target to fuel a devastating alt fire. This large, weighty double-barreled pistol delivers twin projectiles that pack a punch, exploding on impact. Alt fire puts the weapon in lock-on mode. Aim to lock onto multiple targets, then fire to unleash homing missiles.

The Sepulcrum is an Orokin Era weapon created by the Entrati, a burst-fire explosive sidearm that builds charges on kills to allow use of the Alternate Fire, a lock-on missile barrage.


This weapon deals primarily DmgHeatSmall64.png Heat and DmgPunctureSmall64.png Puncture damage.


  • Innate DmgHeatSmall64.png Heat damage – effective against Cloned Flesh, Infested, and Infested Flesh.
  • High DmgPunctureSmall64.png Puncture damage – effective against armor.
  • Primary fire shoots two rounds in a burst.
    • Highest critical chance of all burst-fire sidearms.
    • Above average critical multiplier.
    • Good status chance.
    • Uniquely fires both shots simultaneously instead of consecutively, reducing the chance of one missing.
    • Shots explode in a 1.6 meter radius on impact with a surface or enemy.
  • Alternate Fire activates lock-on mode, targeting up to 5 enemies within 80 meters on the reticle to launch seeking missiles.
    • Highest critical chance and critical multiplier of all launcher sidearms.
    • Very high status chance.
    • Does not use ammo.
    • Shots explode in a 3 meter radius on impact with a surface or enemy.
  • Initial hit and explosion apply status separately.
  • Explosion does not need direct line of sight to deal damage and will penetrate walls.
  • Largest magazine size of all burst-fire sidearms.
  • Can benefit from Mod TT 20px.png Fulmination (Mod TT 20px.png Primed).


  • Innate DmgHeatSmall64.png Heat damage – less effective against Proto Shields.
  • Low DmgSlashSmall64.png Slash damage and DmgImpactSmall64.png Impact damage – less effective against health and shields.
  • Primary Fire:
    • Slowest fire rate of all burst-fire sidearms.
    • Linearly less efficient – sometimes a target may only die with three bullets, which requires an entire second burst to be fired.
  • Alternate Fire:
    • Requires 5 primary fire kills to charge a gauge and cannot toggle without a full gauge.
      • Entire gauge is consumed even without the maximum number of locked-on targets.
    • Requires locked-on targets to fire.
    • Extremely low fire rate.
    • Lock-on homing targets the enemy's body, making it difficult to achieve headshots unless aiming upward.
  • All projectiles have travel time.
  • All explosions inflicts self-stagger.
  • All explosions have linear damage falloff from 100% to 80% from central impact.
  • Slowest reload speed of all sidearms.
  • Low reserve ammo; requires just 2 reloads to fully deplete all ammo reserves.


Sepulcrum is acquired by reaching Rank 2 - Acquaintance with the Entrati. Father sells the main blueprint for ReputationBlackx64.png 4,000 and component blueprints for ReputationBlackx64.png 2,000; a total of ReputationBlackx64.png 8,000 is needed for all parts. The main blueprint is also offered as a rank-up reward.

Additionally requires Rank 0 - Neutral with Solaris United and Rank 1 - Offworlder with the Ostrons in order to acquire Travocyte Alloy and Coprite Alloy respectively required in its construction.

  • One barrel blueprint is required to reach Rank 2 - Clearance: Modus with the Necraloid.
  • Despite ostensibly being unlocked at Rank 2 - Acquaintance with Entrati, the weapon's components require a Trapezium Xenorhast for which the blueprint can only be obtained at Rank 3 - Associate or higher.
  • When the charge gauge is full, Alternate Fire can toggle between its burst-fire and lock-on modes.
    • Up to a maximum of 5 targets can be locked-on by aiming at enemies within 80 meters, indicated by the circular reticule.
    • Locked-on targets are marked by a white diamond.
    • If the target moves 100 meters away or dies while being aimed at, their lock-ons are removed.


  • A sepulcrum is a grave or similar burial place, such as a tomb.
  • The design of sepulcrums magazine is highly reminiscent of a type known as a "casket magazine".


  • Currently the Alt-fire lock on can not be toggled on while aiming, despite playing the audio cue and lockon sound.


Patch History[]

Hotfix 30.7.5 (2021-09-16)

  • Fixed inability to engage the Sepulcrum’s Alt Fire mode while aiming.

Update 29.5 (2020-11-19)

  • Fixed the sound FX that the Sepulcrum plays when you’ve reached 5 kills transmitting to all other players in the squad, regardless of distance.

Update 29.1 (2020-09-17)

  • Decreased the unguided flight time of the Alt Fire on launch from 0.06s to 0.03secs.
  • Decreased the unguided flight time of the Alt Fire smoothing from 1s to 0.4secs.
    • This makes the Alt Fire projectile start to home in on their targets faster and curve more acutely towards them.
  • Decreased Alt Fire re-arming delay from 0.2s to 0.01secs.
  • This decreases the time between being able to lock onto additional targets after the first.
  • Increased max lock distance from 60m to 80m.
  • Increased loose lock distance from 80m to 100m.
    • This increases the distance you can lock onto targets with Alt Fire from 60m to 80m, and lock won't be lost unless the targets move beyond 100m.
  • Fixed cases of the Sepulcrum Alt Fire not properly targeting enemies.

Hotfix 29.0.6 (2020-09-01)

  • Fixed the Sepulcrums Alt Fire homing projectiles sometimes endlessly circling low profile targets like the Deimos Carnis enemy.
