The Mound: Omen of Cthulhu Extraction Guide

Why extraction beats map completion

The Mound: Omen of Cthulhu is a co-op extraction horror FPS from ACE Team and Nacon. Launch from Tempestad, pick contracts, explore the jungle for loot and logbooks, manage sanity and noise, and extract via the ox-wagon before eldritch threats overwhelm your team.

You do not need to clear the entire map. Once contract goals or loot value satisfy the run, route toward extract. Greedy deep pushes after noise spikes are how squads lose everything.

Disambiguation

This page covers ACE Team's video game, not the Lovecraft short story "The Mound." Search intent for the mound omen of cthulhu extraction should land on ox-wagon mechanics, not prose summaries.

Run length expectations

Preview coverage cites roughly 20–30 minute expeditions — typical extraction-horror pacing. Plan extract before fatigue causes sanity mistakes or noise chain aggro.

Solo vs squad extract

Solo play supports AI companions, but solo death ends the expedition — higher stakes than squad revives. Extract earlier with partial value instead of heroic last-chest dives.

Crossplay squads

Mixed PC and console parties via crossplay should agree extract keywords before drop — latency hurts last-second "wait for cart" confusion.

Loading loot during the run

Transfer treasure and contract items onto the ox-wagon as you secure them — not only at extract. Downed carriers drop body loot; cart banking insulates against partial wipes when the defender holds position.

Revives at the cart

Some contracts include reviving salt for field revives. When supplies are gone or the area is too hot, teammates can be killed and carried to the ox-wagon for revival at the cart — coordinate before panic firing.

Six-slot inventory discipline

Each explorer carries six slots. Balance weapons, rain backups, healing, objectives, and high-value treasure. Items can be shared among teammates — call out who holds the team map before splitting paths.

When to call extract early

Once loot value or contract objectives are satisfied, pivot to the white line — do not 100% the map. One more chest after a noise spike is the most common extract fail.

Fort and logbook detours

Logbooks in fort tents tempt squads into deep detours. Bank confirmed finds on the cart, then decide as a group whether the next fort is worth extract delay.

Extract under pressure

Defenders cover the cart while carriers sprint to the boat line. Quiet weapons help — see noise guide for crossbow-first extract defense.

Deer and bonus value

Wild deer are an easy bonus value source when taken quietly — low risk Tokens for squads learning aim and noise timing before extract.

Contract payout vs loot greed

Contracts scale Basic → Legendary with better starting gear and harder enemy pressure. Match tier to extract confidence — a finished Basic extract beats a wiped Legendary push.

Phase 2 value tools

A dedicated value calculator is planned for Phase 2. Until then, use conservative "leave early" math when cart value already satisfies the board objective.

Starting gear scales with tier

Harder contracts grant better shared equipment at drop. There is no skill tree — power comes from rank, Tokens, weapon upgrades, and squad coordination per beginner progression notes.

Logbooks and map unlocks

About 13 logbooks unlock map knowledge; achievements land at 7 / 13 collected. Maps with dashed white lines indicate logbook forts — plan dedicated hunts after routine extracts feel safe.

Loadout synergy

Match loadouts to contract type — quiet scouts for logbook routes, heavier defenders for escort extracts. Rain backups mandatory for firearm teams on weapons.

Noise during extract

Loud firearms during the final minute can chain enemy into the boat gather. Call "going loud" only when the squad is anchored — details on noise guide.

Sanity at extract

False horns and phantom teammates lure carriers away from the white line. Use the sanity guide phrase kit — Anchor: back to cart — before sprinting toward audio bait.

Patron Saint edges

Carved patron saints can include weather or resilience blessings. Rain control saves firearm-heavy teams during long cart escorts — verify saint text in-game after patches.

Rank and landing zones

Rank progresses toward ~30, unlocking new landing zones on maps. Extract consistency beats occasional jackpot wipes for long-term unlock pace.

Demo progress note

Pre-release demo saves may or may not transfer — confirm the latest developer note on updates before advising friends their logbook progress is safe.
