The Game Bakers have dated the first free installment in Cairn’s On the Trail DLC series — On the Trail: Deep Water — for October 29, 2026 on PlayStation 5 and PC (Steam / Epic / GOG), per Gematsu (Sep 20 English wire summarizing the studio overview).
Free Oct 29 — water soloing, three areas, Marco playable
Deep Water is framed as the first of a series of free downloadable content that follows the trail of a legendary climber with new locations and challenges. Headline features from The Game Bakers:
- Three new climbing areas
- Water soloing — climb over water without the usual fall-to-death consequence
- Marco joins the climb: players can now climb with Marco or Aava (Marco is no longer sidelined as a cheerleader)
Price: free. Do not invent a paid tag.
Soft aside — Switch 2 base game early 2027
Cairn is available now on PS5 and PC. A Nintendo Switch 2 version of the base game is due early 2027 — calendar aside only; this DLC wire does not confirm Switch 2 Deep Water timing.
