How to Prepare Your First Expedition in The Mound: Omen of Cthulhu

Aboard the Galleon Tempestad

Every run in The Mound: Omen of Cthulhu begins aboard the galleon Tempestad, where Alonso de la Torre, Don Rodrigo de Medina, Leonor, and Fray Gaspar frame the expedition. Preview footage shows a prep phase where the squad reviews contracts, divides equipment, and confirms insertion points before rowing ashore. This is not cosmetic downtime: the weapons and consumables you assign here are the only ones you carry until extraction or defeat. Demo sessions suggest roughly twenty-minute mission targets, so inefficient prep cuts into jungle time.

Before accepting a contract, gather your four players on voice chat—spatial voice chat is supported in-game, but pre-mission planning still benefits from open mics on the galleon. Cross-play between PC, PlayStation 5, and Xbox means mixed squads are expected; agree on input types and who will call compass directions. First-time groups should pick shorter, demo-familiar contracts rather than branching toward fort interiors or Mound-adjacent zones until everyone understands revive timing and sanity cues.

Dividing Core Gear

Preview builds highlight a fixed pool of shared expedition gear: muskets, a crossbow, swords, an oil lamp, and reviving salt. These items are limited, so arguments on the Tempestad deck are part of the design. A practical first-expedition split observed in demo play: one musket for overwatch, crossbow to the player comfortable with quiet kills, swords distributed to two front-line explorers, the oil lamp held by whoever leads navigation through dark tree cover, and reviving salt assigned to the most disciplined player who will stay near downed allies.

Muskets are powerful but loud. Jungle noise attracts threats, and firearms are scarce relative to melee options. First runs should treat musket fire as an extraction alarm, not a opening-move tool. The crossbow fills the gap for silent elimination when preview AI patrols allow it. Swords are reliable when stamina and positioning are managed, but they require closing distance—dangerous when sanity hallucinations make flanking paths ambiguous. See our Weapons, Noise, and Combat guide for noise-radius details from preview streams.

The oil lamp is both utility and risk: it reveals paths in murk but may draw attention in open marsh segments shown in early footage. Pass the lamp when the holder's sanity meter rises into yellow tiers previewed in UI mockups. Reviving salt is non-negotiable for co-op success; without timely revives, dead allies can become corrupted according to developer comments at preview events. Pair salt allocation with the Co-op Survival guide.

Choosing Your First Contract

Contracts act as mission templates: objective type, target region, and reward tier. Demo-available contracts skew toward peripheral jungle zones rather than the central Mound, which aligns with tutorial pacing. Select objectives that require retrieval or survey markers near the beach insertion shown in Steam Next Fest builds. Avoid chained fort objectives until your squad reads Forts and Logbooks and understands how logbook unlocks shorten travel time on later runs.

Reward tiers in preview UI imply better gear or currency for riskier contracts. First expeditions should prioritize learning extraction windows over maximizing payout. A failed twenty-minute run teaches less if you wipe ten minutes in because you accepted a fort breach contract without ranged support. After two successful extractions, escalate to contracts that push inward toward zones documented in Jungle Zones.

Pre-Departure Checklist

Use this demo-tested checklist before leaving the Tempestad: confirm four roles (navigator, lamplighter, ranged support, revive anchor); verify cross-play party invites; agree on a extraction call word; set a musket-use policy (preview squads often restrict to emergencies); brief everyone on private hallucinations via the Sanity System guide; mark fort logbook locations if your contract passes near known structures; and confirm audio settings so spatial voice chat levels are audible over jungle ambience.

When the rowboats hit shore, move as a unit until you establish a baseline noise profile. Preview footage shows wildlife reacting to sprinting and clashing steel long before gunfire. Your first expedition succeeds when everyone extracts with shared loot—not when someone heroics a solo push into unseen tree lines. Treat the galleon prep phase as the strategic half of the twenty-minute loop described in Extraction Loop gameplay docs.
