The Hydra is the new signature ARC threat arriving with ARC Raiders' Frozen Trail update on October 8, 2026 — a three-part turret boss found aboard the Frigate that Embark says can "handle entire squads." If you want to be first through it on day one, here's exactly what Embark has confirmed, how the fight is built to work, and the loadout and tactics that give you the best shot at cracking it.
Quick answer: The Hydra is a stationary ARC turret aboard the Frigate (the new airborne-carrier zone in Frozen Trail). It's split into three stacked, autonomous portions, each with its own weaponry, and Embark's press release confirms it can target multiple players at once and "respawn." It doesn't walk, but it repositions and tracks. Embark's own counterplay: divert its attention, find cover fast, and attack in rapid windows. Exact HP, weak points and drops have not been disclosed in the official sources yet.

Key takeaways
- What it is: a new ARC turret boss — "may not traverse, but it sure does move" — split into three stacked and autonomous portions with a "triple-threat of weaponry."
- Where: found upon the Frigate, the new high-tier airborne-carrier zone patrolling Pendola Pass, tuned for "highly skilled Raiders."
- The twist: the press release confirms it can target multiple players at once and respawn — so it punishes tunnel-vision and rewards splitting aggro.
- Live date: part of Frozen Trail, October 8, 2026 — ARC Raiders' first-anniversary update.
- Unknown (don't get baited): no official HP pool, no confirmed weak points, no loot table. None of these have been disclosed in Embark's official sources, so treat any exact numbers before Oct 8 as unconfirmed.
What is the Hydra in ARC Raiders?
The Hydra is one of three new ARC enemies revealed in Embark Studios' Frozen Trail First Look (September 23, 2026), alongside the Bully and the Skulker. It is the marquee encounter of the update, and unlike the roaming Bully and ambushing Skulker, the Hydra is fixed in place — a boss-class turret rather than a chaser.
Embark describes it directly: "This enemy may not traverse, but it sure does move. Split into three stacked and autonomous portions, the Hydra is a turret that can handle entire squads with its triple-threat of weaponry. Found upon the Frigate, the Hydra will require a tactical approach in which Raiders divert attention, find cover quickly, and attack rapidly when the moment arises."
Two words there matter more than the rest: autonomous and respawning. Each of the three stacked sections operates on its own — three separate weapon systems tracking the arena at once — and Embark's official press release adds that the Hydra is "an ARC capable of targeting multiple players at once and respawning." Embark hasn't spelled out exactly what "respawning" restores, but plan for a Hydra that doesn't stay down easily — burning one section quiet may not be the same as ending the fight.
If you've fought the Matriarch — the colossal walker that summons a full support suite — the Hydra is the opposite archetype: it won't chase you across the map, but it owns the room it sits in and forces you to work angles around a threat that never has to reposition to keep pressure on you.
Where to find the Hydra: the Frigate
The Hydra lives aboard the Frigate, which is itself brand new in Frozen Trail. When one of ARC's Emperors falls on the new map, Pendola Pass, ARC responds by sending "one of their largest vessels to patrol the area — Raiders have started calling it the Frigate." (The name is player slang in-fiction, not an ARC designation.)
The Frigate is not a casual drop-in. Embark frames it as "a substantial challenge to highly skilled Raiders." The loop: find a way to get on board, then "navigate its internal passageways, unlock paths, and defend yourself against ARC new and old" — all in close quarters, hundreds of feet in the air. Rival Raiders are inside chasing the same prize, so you'll be forced to "collaborate or cut through them in order to pass."
That environment shapes the whole Hydra fight. You're likely engaging a stationary triple-turret in tight interior corridors, with limited sightlines, possible verticality, and the constant risk of a rival team third-partying the moment you commit. The Frigate is also excluded from the PvE matchmaking test (Oct 13–20) precisely because it's one of the game's highest-tension spaces — this is intended to be hard.
Note: Embark's August 12 announcement promised "an enormous new ARC Operation designed for experienced Raiders." The Frigate is the only revealed feature that matches, but Embark has never officially applied the "ARC Operation" label to it — treat Frigate-as-Operation as strongly implied, not confirmed.
How to beat the Hydra: confirmed tactics
Embark has spelled out the intended counterplay in plain terms. Everything below is anchored to what the developer has actually said — the specific damage tuning will only be knowable once the update is live.
1. Divert its attention
The Hydra's three autonomous portions can target multiple players at once, which means a squad that all pushes the same angle just feeds three weapon systems into one kill zone. The intended answer is to split aggro: have teammates pressure from separate lines of sight so no single portion can lock every Raider at once. Solo players will feel this most — with no teammate to pull a barrel off you, there's nothing to stop all three portions locking onto you at once.
2. Find cover quickly, then peek
"Find cover quickly" is Embark's second instruction, and it's the core rhythm of the fight. Because the Hydra is a turret, its danger is sustained tracking fire, not a lunging melee. The Frigate's tight interior geometry is your friend here: break line of sight, let the tracking reset, and never stand in the open trying to trade with three barrels. Treat every exposed second as borrowed.
3. Attack in rapid windows
The last piece — "attack rapidly when the moment arises" — is about damage discipline. You do your damage in short, committed bursts when a portion is reloading, repositioning its aim, or drawn onto a teammate, then you're back behind cover before the tracking catches up. Sustained DPS in the open is how the Hydra "handles entire squads." Burst-and-break is how you avoid it.
4. Plan for the respawn
Because Embark confirms the Hydra "respawns," don't assume the fight is won when a section goes dark. Keep your positioning and ammo economy honest through the whole encounter rather than dumping everything to drop one portion and then getting caught flat-footed when it comes back online. Bring enough ammunition and healing for a long, staged fight — not a single burst-down.

Best loadout to prep for the Hydra
No official weak points or damage values exist yet, so the smart play is to bring proven ARC-killing tools rather than chase a "one weird trick." Against a heavily-armored, multi-part ARC boss, the community's standard boss-killer package still applies:
| Priority | What to bring | Why it helps |
|---|---|---|
| Weapon | High-damage armor-breaker — the Bettina assault rifle or the Hullcracker grenade launcher are proven ARC-boss picks | Reliable armor damage from cover; rewards precise burst windows |
| Ammo | Bring roughly double what you'd take on a normal raid | A staged, respawning fight burns through ammo fast |
| Healing | Max stims/med kits | Frigate is close-quarters and long; expect chip damage |
| Utility | Cover-creating and repositioning gadgets | Frozen Trail's new Grapple Hook and shields help you break tracking |
| Mindset | Squad comms + split angles | The Hydra is explicitly built to punish stacked pushes |
Frozen Trail also introduces Amplified Weapons — a fifth quality tier unlocked at the Outpost's fully-upgraded Research Workstation, rolling out to 15 weapons at launch (Embark's examples include a fully-automatic Burletta and a Rattler with incendiary rounds and a 64-round magazine). If you can amplify a heavy hitter before you attempt the Frigate, that extra ceiling of sustained damage is exactly what a respawning multi-turret fight asks for.
If grinding the blueprints, materials, and gear to be Frigate-ready before day one isn't how you want to spend launch week, our team can fast-track the loadout for you:

Hydra vs the other new Frozen Trail ARC
The Hydra is one of three new machines. Knowing the other two helps you read the Frigate:
- Bully — a "machine-learned," oppressive melee bruiser that "gallops upon your position" with a host of lethal attacks. Fast on its feet; use cover, time your response, hit your shots.
- Skulker — an opportunistic ambusher that skirts the edge of vision, retreats when distracted, then unleashes "a flurry of blows." A flanker, not a brawler.
The Hydra is the stationary anchor of that trio — while Bullies and Skulkers may harass you elsewhere on Pendola Pass and inside the Frigate, the Hydra is the fixed centerpiece you have to solve with position rather than outrun.
Frequently Asked Questions
Where is the Hydra in ARC Raiders? The Hydra is found upon the Frigate, the new airborne-carrier zone introduced in the Frozen Trail update. The Frigate patrols the new map, Pendola Pass, and is designed for highly skilled Raiders who first have to find a way to board it.
When can I fight the Hydra? The Hydra arrives with Frozen Trail on October 8, 2026, ARC Raiders' first-anniversary update. It is not available before that date.
How much health does the Hydra have? Embark has not disclosed the Hydra's HP, weak points, or loot in any official source. Any exact numbers circulating before launch are unconfirmed. We'll update this guide with verified values once the fight is live.
Can you solo the Hydra? Embark hasn't confirmed solo viability, but the design points against it: the Hydra's three portions can target multiple players at once and it "can handle entire squads," and the intended tactic is to divert its attention — which is far easier with teammates splitting aggro. A solo attempt will be the hardest way to take it on.
What's the best way to beat the Hydra? Follow Embark's stated counterplay: split its attention across your squad, break line of sight and use cover the moment you're targeted, and only push damage in short windows when a portion is reloading or drawn onto a teammate. Bring extra ammo and healing because it can respawn its portions.
Is the Frigate the new ARC Operation? It's strongly implied but not officially confirmed. Embark promised "an enormous new ARC Operation" and the Frigate is the only matching feature revealed, but the "ARC Operation" label has never been applied to it directly.
Bottom line
The Hydra is Frozen Trail's showpiece fight: a stationary but relentless three-part turret aboard the Frigate, built specifically to break squads that push carelessly. You beat it the way Embark designed it to be beaten — split its attention, respect its tracking, and burst it down in windows — not by trading in the open. Come in over-supplied on ammo and healing, ideally with an amplified heavy weapon, and treat the respawn as part of the fight rather than a surprise. Get your gear sorted before October 8 and you can be one of the first Raiders to actually crack the Frigate instead of feeding it.
