Your First Expedition, Made Clear

The Mound: Omen of Cthulhu is built around preparation, shared information, and knowing when to leave. Before landing, read the contract, split limited equipment across the crew, and agree on a return plan. In the jungle, stay close enough to verify suspicious sights, control noise, secure mission value, and extract before injuries or sanity pressure turn a successful route into a loss.

Field Workflow

The Expedition Loop at a Glance

A good run is a sequence of controlled decisions. Use this loop as a crew checklist, then open the detailed guides when a step keeps failing.

  1. 01

    Read the contract

    Confirm the objective, value target, route, and the point where the team should stop taking extra risk.

  2. 02

    Divide the loadout

    Share weapons, light, healing, utility, and carrying capacity instead of building four identical kits.

  3. 03

    Move as a crew

    Keep teammates and the return anchor within reach. Compare what each player sees before reacting.

  4. 04

    Secure value early

    Protect objective items and useful loot. Avoid spending ammunition and health on threats you can bypass.

  5. 05

    Extract on purpose

    Leave when the objective is safe or the run becomes unstable. A controlled return is part of the mission.
