Great Hunts Campaigns

Three world-boss campaigns, each a branching set of Open-World operations run from the CONT4CT Device (not the regular mission terminal) — progress and World Outcomes are shared for the whole session, so pick a host and stick with them for the run.

Quarrite (Olympus) — 11 missions → Mining Armature

Opens with Missing Miners, then branches through Habitat, Prototype, Brilliance, Liberation, Weakness, Research, Repercussion, Elimination and Rebuilding before both remaining tracks converge on the Earthquake finale.
Key unlocks along the way: Quarrite Sledgehammer, Prototype Drill Arrow, a full Caveworm armor set, Quarrite Gun + Grenade, Carbonweave Backpack, a full Carbonweave armor set, Prototype Mini Thumper, Quarrite Armor Attachment and Quarrite Mining Module. Earthquake pays out the Mining Armature plus Quarrite trophies, a lamp and a throne for a base.

Garganutan (Styx) — 12 missions → Anti-materiel Rifle

Opens with Breakout into Enclave, then fans out through Curiosity, Sellout, Compliance, Blood Thirst, Ethics, Strange Troop, Expurgation and Ape Escape before converging on Obliteration and the Extinction finale.
Key unlocks: a Battered lab-furniture set, Garganutan Sonic Attractor, Garganutan Fishing Trap, Frenzy Tonic, Force Attachment, Damage Module, Garganutan Grenade, a Banana Farming Packet and a full Garganutan armor set. Extinction pays out the Anti-materiel Rifle plus a Garganutan trophy and rug.

Rimetusk (Prometheus) — 11 missions → Tactical Bow

Opens with Survivors, then branches through Experiments/Research, Mutation, Prevention/Hypothesis, Destruction, Supplementary/Fieldwork and Propagation before converging on the Glaciation finale.
Key unlocks: an ECHO Device, Rimetusk Frost Attachment, a second Prototype Drill Arrow, Rimetusk Snap Trap, Luriform Serum, Enzymatic Mutation Ammo, a full Arctic Survival armor set, Rimetusk Spear + Javelin, a full Rimetusk armor set and Rimetusk Shield. Glaciation pays out the Tactical Bow plus Rimetusk trophies and a chandelier.

Rewards

Regular ops pay 200 Ren each; every campaign finale pays 500 Ren on top of its signature weapon and cosmetic trophies. Run start to finish: Quarrite totals 2,500 Ren (10 ops + Earthquake), Garganutan 2,700 Ren (11 ops + Extinction — it has the extra mission), Rimetusk 2,500 Ren (10 ops + Glaciation). All three back to back: 7,700 Ren, before counting any Exotics the individual extractions also pay out.

Difficulty

Each campaign ramps from 2-star ops early to a single 4-star mission — the finale, in all three cases. Two of the three finales, Earthquake and Extinction, specifically flag poison/toxic gas as a hazard; stock Anti-poison items (see the Weather & Hazards guide) beforehand. Rimetusk's Fieldwork flags severe weather/storms even though it isn't the finale — difficulty and hazard don't always peak on the same mission.

Crew doctrine

• These aren't a single-file line — several missions unlock in parallel, so a crew can split up and clear branches at once rather than queueing one at a time.
• Missions carry permanent World Outcomes that change the Open World for good; treat a Great Hunt as a one-way commitment for that world, not a casual drop.
• Each finale is a raid fight: stage ammo depots and fallback shelters beforehand, and plan staggered revives rather than one grouped position.
