About Trailmakers High Seas Expansion

Take to the seas and dive headfirst into a new Trailmakers experience, with our completely revamped physics-based system for weather - the wind and waves in High Seas will challenge your skills like never before!

High Seas presents players with a sandbox playground, complete with new elements to play with. Explore a gigantic, stunning new map both above and below water, and delve into four new distinct environments in the High Seas islands (each with 35 artifacts to find):

? Coral Cove: A tropical paradise, the perfect place for a pirate ship to call home.



⛰️ Green Haven, a vision of Viking wilderness with towering pines and dramatic rock formations.



❄️ Sub-Zero Archaeology Base, a frozen desolation in the north of the High Seas.



? Mount Magma, a molten mountain that’ll test your resourcefulness and resolve.



The vast new landscape that is home to each new island comes with its own unique vegetation, animal life to explore and hundreds of hidden treasures and secrets to uncover.

Embody your inner sailor with one of the new hats, use the new functional blocks to become master and commander of the waves in the builder, and make anything from giant surfboards to luxury yachts or fully rigged tall ships in the world of the High Seas, and make it all your own with the exclusive new vanity blocks.

High Seas features:

  • A large new map with four new islands to explore
  • 100+ hidden treasures to collect
  • Secret locations to uncover
  • A brand new weather system with wind and wave physics
  • A wide selection of new functional and accessory blocks including sail blocks and new seats

Additionally, the skins available from the Skin Pack DLC’s are compatible with the new Hull Blocks used to create ships.

Most common FAQs when buying Trailmakers High Seas Expansion for PC in digital format:

It is a key that will allow you to download the game Trailmakers High Seas Expansion on your PC from official download platforms.
As of 28/09/2026, in United States, the best price we have found in our selection of online stores that include the key for Trailmakers High Seas Expansion on PC is €4.99 (no fees).
The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Trailmakers High Seas Expansion to your game library. The account format requires more complicated steps and is more prone to errors during activation.
The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Trailmakers High Seas Expansion, and they will provide a new key. You can also contact us, and we’ll help you out.
Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.

In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.
