About Trailmakers High Seas Expansion
Trailmakers High Seas Expansion adds a large sandbox map with four islands to explore, new building blocks and weather physics based on wind and waves. You can build and customize vessels, search for treasures and secrets, and explore environments above and below the water.
The High Seas islands
The map includes four distinct environments, each with 35 artifacts to find:
- Coral Cove: a tropical island suited to pirate ships.
- Green Haven: a wilderness of towering pines and dramatic rock formations.
- Sub-Zero Archaeology Base: a frozen northern outpost.
- Mount Magma: a molten mountain that tests your resourcefulness.
Each island has its own vegetation and animal life, and the landscape contains more than 100 hidden treasures and secret locations to discover.
Build and sail
New functional and accessory blocks include sail blocks, new seats and exclusive vanity blocks. You can use them to build vessels ranging from giant surfboards and luxury yachts to fully rigged tall ships. New hats let you customize your character, and skins from the Skin Pack DLCs are compatible with the new Hull Blocks used to build ships.
Wind and waves
The expansion introduces a revamped physics-based weather system. Wind and waves affect your time at sea and challenge your building and sailing skills.
