Haalvu

Automatic rifle with multi-target alt-fire

Released Jul 11, 2026

Haalvu is an automatic rifle with a 150-round magazine, one-second reload, and two distinct firing modes. Its alt-fire splits the weapon into rifles that can track up to four targets at once while using more ammunition per shot. Consider it when you value sustained primary fire or multi-target tracking from the alternate mode.

Haalvu GUIDE

Understand Haalvu

Useful when…

  • Use normal fire for automatic hit-scan shots with a large magazine and quick listed reload.
  • Use alt-fire when you want the split rifles to track up to four targets and can account for higher ammunition use.

Normal fire

The normal attack is automatic hit-scan fire at 13 shots per second, with 25% critical chance, a 2.5× critical multiplier, and 19% status chance. The weapon-level damage lists 33 Tau damage, but the attack-level damage object is empty; therefore a per-mode damage value cannot be assigned from the attack record. The magazine holds 150 rounds and reload time is one second.

Alt-fire and its cost

Alt-fire is listed separately at 12 shots per second, 20% critical chance, a 1.8× critical multiplier, and 26% status chance. Its description says the weapon splits into rifles that track up to four targets at once, while consuming more ammunition per shot. The attack-level damage object is also empty here, so no numeric alt-fire damage can be stated.

Build and alternatives

The two modes have different listed critical and status chances, so investment should reflect which mode you use; no upgrade tracks are listed. Basmu is described with explosive bolts or chain-capable plasma beams and a health-leech effect when its regenerative battery is drained. Acceltra instead fires rapid plasma rockets, while Kuva Quartakk distinguishes hip-fire automatic fire from four simultaneous aimed shots. These are specific alternate handling options, not established substitutes for Haalvu’s four-target tracking alt-fire.

Limitations and tradeoffs

  • Alt-fire consumes more ammunition per shot than normal fire.
  • The supplied per-attack damage entries are empty, so damage cannot be compared numerically between modes.

Common mistakes to avoid

  • Assuming alt-fire uses the same ammunition per shot as normal fire.
  • Assigning the weapon-level Tau damage value to each attack mode when their attack-level damage entries are empty.
