Hullcracker
The Hullcracker is a pump-action launcher whose explosive projectiles only detonate on ARC — a dedicated anti-machine specialist and the go-to pick for armor-heavy PvE and the ARC Turbine boss. It sits at the top of the Overall (armor-pen) axis for structure/weak-point burst, but is near-useless in PvP.

Full guide →Swap to it for boss phases and armored elites; run a generalist (Anvil/Bettina) for trash and PvP.
Best Attachments
- Vertical Grip II — Steadies the launcher so shots land on the weak point.
- Lightweight Stock — Faster ADS/handling to keep the launcher on target between shots.
- Kinetic Converter — Alternative stock slot that speeds up follow-up fire.
Strengths
- +Best-in-slot against armor and bosses — the top ARC Turbine pick.
- +High weak-point burst that punishes exposed elites.
- +Fits the current PvE meta that values fast boss phases.
Weaknesses
- −Poor PvP value — projectiles do not detonate on players and bounce unreliably.
- −Overkill and awkward against unarmored mobs.
- −Committing to it taxes a weapon slot you rely on teammates to cover.
Why This Tier
Very Strong on the Overall (ARC armor-pen) axis — anti-machine explosive burst is its entire purpose and it is #1 for the ARC Turbine fight.
