Oceanhorn 3: Legend of the Shadow Sea macOS Free Download is an open-world action RPG from Helsinki-based studio Cornfox & Brothers, the third mainline entry in a series that began with Oceanhorn: Monster of Uncharted Seas and continued with Oceanhorn 2: Knights of the Lost Realm.
The setup: the story picks up roughly a thousand years after Oceanhorn 2. You play the newest Red Town Explorer, sailing the treacherous Shadow Sea to hunt down a long-lost god, fight enormous Titans, and recover the knowledge needed to restore the ruined world of Arcadia. Along the way you cross paths with Em, a technopirate tied to the Titans, and her crew aboard the Warlock’s Revenge.
Cornfox describes it as roughly 20+ hours of main story plus a substantial pile of optional side content. Importantly for newcomers: the story is self-contained. You don’t need to have played the first two games.

Oceanhorn 3 macOS System Requirements
This is the section most people land here for, so here it is up front.
Minimum: macOS 12.0 (Monterey) or later.
That’s the officially listed floor on the Mac App Store. A few practical notes on top of the official number:
- Apple silicon is strongly recommended. Oceanhorn 3 runs on Unreal Engine 5 and is, by the developer’s own admission, a demanding title. M-series chips (M1 and newer) are the realistic target hardware.
- Free up memory before you play. Cornfox explicitly advises closing background apps — this is not a game that shares GPU headroom gracefully with a dozen Chrome tabs and Final Cut.
- An Apple Arcade subscription is required. The game is an Arcade exclusive; there’s no standalone purchase option.
- Recent updates added device support for newer hardware including the MacBook Neo, alongside general performance and stability optimizations.
What’s New in Oceanhorn 3
A rebuilt combat system
The headline change is the Skill Drawer — a tactical pause that lets you stop mid-fight and pick exactly the ability, item or heal you need. Alongside it, Quick Skill slots let you bind favourite actions for uninterrupted real-time play. It’s a deliberate attempt to serve both players who want reflex-driven action and those who want to think through an encounter.
Your companion Gero brings unique abilities into that same menu, adding a light party-management layer the earlier games never had.
Character progression
For the first time in the mainline series, you build your hero. Collect Anima and other resources from defeated enemies and environmental exploration to shape how your character develops.
First-person mode
A series first: you can drop into your hero’s eyes and explore the Shadow Sea in first person. On a large Mac display this is more than a novelty — the art direction holds up close.
The Stream of Creation
A traversal and world-manipulation mechanic that lets you reshape your surroundings, used for both puzzles and combat
