Free Temple of Yig DLC — The Mound: Omen of Cthulhu
How to claim free Temple of Yig DLC for The Mound — exclusive jungle mission, co-op hosting rules, and differences from Deluxe Edition content.
Free Launch DLC Overview
At launch on July 15, 2026, Nacon offered Temple of Yig as free downloadable content—a exclusive mission contract sending expeditions into a distinct cursed jungle area with unique threats and environmental hazards. The zone draws on serpent-cult Lovecraftian themes separate from standard coastal and fort-adjacent contracts documented on Contracts.
The free DLC is available to all Standard Edition owners—not locked behind Deluxe. Deluxe Edition also bundles Temple of Yig inside its premium package alongside Fortune Hunters characters and Abyssal Gear cosmetics—see Deluxe Edition for the full $39.99 USD breakdown versus $29.99 USD Standard.
ACE Team and Nacon marketed the free mission as part of a generous launch package alongside the twenty percent Steam discount through July 29, 2026 and the complimentary Lost Explorers' Swords Pack cosmetic DLC on the same deadline.
How to Claim on PC
Temple of Yig does not auto-add to your library—you must claim it manually on your PC storefront. On Steam: open the game hub, scroll to DLC section, locate Temple of Yig or the free mission listing, and click install/add to account before launching the game. Epic Games Store users should check the game's DLC tab for the equivalent free add-on listing.
After installation, verify the DLC appears in your owned content before hosting co-op sessions. Mixed squads only need the session host to own and install Temple of Yig for participants to join Yig briefings—same hosting rule as Deluxe-exclusive mission content. Confirm loadout and contract selection aboard the Tempestad per First Expedition guide.
Console players should check PlayStation Store and Microsoft Store DLC sections—free mission availability may differ by platform promotion timing. This wiki tracks PC free-claim steps confirmed at Steam launch; update console paths when Nacon posts platform-specific guides.
Co-op Hosting and Mission Tips
Only the host needs Temple of Yig installed for co-op Yig contracts, but every player should understand sanity escalation in enclosed temple-adjacent zones. Assign lamp and salt roles before disembarking—serpent-themed areas may compress sightlines compared to open marsh tiles from demo coastal runs.
Cross-play squads must match game versions and use the server browser if direct cross-platform invites fail—details on Cross-Play. Push-to-talk at launch reduces open-mic noise during tense temple corridors; see Co-op and Voice Chat.
Pair Yig runs with Jungle Zones knowledge and Combat Strategies for musket discipline in tight spaces. Extract with partial loot rather than wiping on first Yig attempts—token rewards feed the Weapon Upgrade Anvil between runs.
Free DLC Versus Deluxe Bundles
Standard owners receive Temple of Yig free at launch while Deluxe adds Fortune Hunters characters (two extra playable explorers), Abyssal Gear weapon cosmetics, digital soundtrack, and Lost Explorers' Swords—without gating the Yig mission itself. Mixed squads do not need matching edition tiers; Deluxe-only characters apply only to players who purchased that content.
Lost Explorers' Swords Pack is a separate free cosmetic DLC on Steam through July 29, 2026—claim via "Add to Account" on the DLC page. It is not the same entitlement as Temple of Yig; install both before your first expedition if you want rapier skins and Yig contracts available.
Track promotion deadlines on Post-Launch Updates and Pre-Order Bonuses. After July 29, sword DLC may return to $4.99 USD paid listing while Temple of Yig free claim status depends on Nacon storefront policy.
