Patch 1.01 Live — July 21, 2026
ACE Team's first post-launch hotfix addresses optimisation, inventory QoL, crossplay lobby discovery, and balance feedback from the first six launch days. PC players who tested the July 17 Open Beta should revert to the default Steam branch or restart the client so versions match console friends.
Headline features: improved PC performance profiles and console optimisation; server-browser passwords for private mixed-platform groups; mouse inventory sorting during ox-wagon interactions; first-launch camera choice between Cinematic and Standard profiles; key bindings persist between sessions. Balance adds a machete to all mission starting gear, reduces Creeping Canopy (spider) damage by fifty percent, and tunes enemy damage, stamina, knife, and pole-weapon reach.
Bug fixes include Mi-Go search behavior (they now appear reliably), T-posing death animations, bleeding state replication, wall-climb stuck cases, isolation fog crashes, and distant LOD pop-in. Known issues remain: Saints disappearing after one expedition unless the lobby restarts, and intermittent in-game mic pickup—both targeted for a follow-up patch. See the dedicated Patch 1.01 page for the full numbered list.
Launch Discounts and Early Adopter Bonus
Steam wishlists surpassed 800,000 before launch, unlocking Milestone 3 and a confirmed twenty percent discount on Standard and Deluxe editions through July 29, 2026 per Nacon Steam news. Standard Edition drops to $23.99 USD during the promotion; Deluxe to $31.99 USD before regional tax. Console pricing follows PlayStation Store and Microsoft Store listings and may differ from Steam percentages.
The Lost Explorers' Swords Pack DLC is free to claim on Steam through July 29, 2026—two ornate rapier cosmetics via the "Add to Account" button on the DLC store page. You must own the base game to claim it; the pack costs $4.99 USD after the promotion ends. Early Adopters who purchase the base game within the first two launch weeks also receive the sword pack bundled per Nacon announcements.
Standard Edition lists at $29.99 USD; Deluxe at $39.99 USD before discounts. Deluxe bundles Fortune Hunters characters, Abyssal Gear cosmetics, digital soundtrack, and sword pack per July 2026 storefront listings—see Deluxe Edition.
Free Temple of Yig DLC and Extended Demo
At launch, Nacon offered free DLC Temple of Yig—an exclusive mission contract in a unique cursed jungle area. Claim it manually on your PC storefront; it does not auto-add to your library. Only the session host needs the DLC installed for co-op participants to join Yig briefings, similar to Deluxe mission hosting rules.
ACE Team kept the Steam playable demo active for approximately one week after Next Fest ended, letting new players practice coastal loops before buying. Demo progress carryover to retail has not been confirmed—treat demo saves as training. Demo changelog history remains on Demo Patch Notes.
Launch-week content creators could enter Nacon's demo clip contest for a four-pack of game keys—promotion may have ended at retail unlock; watch official social channels for post-launch events.
Launch Promotions — Six Days Remaining (July 23)
As of July 23, 2026, six days remain before several launch promotions end on July 29, 2026. Steam's twenty percent introductory discount on Standard and Deluxe editions, the free Lost Explorers' Swords Pack DLC claim, and the Early Adopter sword bundle for buyers in the first two launch weeks all share the July 29 deadline per Nacon Steam news. Claim cosmetics via "Add to Account" on the DLC page—they do not auto-install.
Nacon also sells the Supernatural Co-op Horror Bundle on Steam, pairing The Mound: Omen of Cthulhu with Dark Hours—another co-op survival horror title—at ten percent off stacked atop existing discounts. If you already own one game, Steam completes the set by charging only the missing title. Details on Pre-Order Bonuses and Deluxe Edition.
Physical disc editions for PlayStation 5 and Xbox Series X|S arrive August 6, 2026—fourteen days from July 23 per Nacon's launch announcement. See Physical Edition. Console storefront pricing may differ from Steam percentages.
Launch Systems Changelog
Day-one retail includes systems the demo lacked or only partially showed. The Weapon Upgrade Anvil on the Tempestad spends contract tokens to improve gear between runs—full guide on Weapon Upgrades. Push-to-talk voice ships for clearer squad callouts when sanity distorts perception. The mandatory mission-end timer is removed so crews can linger for loot as long as they survive.
Comfort options expanded: FOV slider now ranges 75–125, and a centre-screen focus dot helps motion sickness. Treasure shrines, mainland loot, and contract clarity also received launch polish. Cross-play works, but direct cross-platform invites currently require the server browser—details on Cross-Play and the dedicated Launch Patch Notes page.
Nacon confirms eighteen handcrafted maps at launch, eight playable characters with four available day one, and a physical disc edition for PS5 and Xbox Series X|S on August 6, 2026. NVIDIA DLSS 4.5 ships day one on PC—tune via PC Graphics & DLSS 4.5.
