Twin Sails Interactive games

About Twin Sails Interactive

Based in France, Twin Sails Interactive publishes work from independent teams rather than developing in house, and it has become closely associated with digital versions of tabletop favourites. Gloomhaven brings campaign-driven tactical combat to PC, while Terraforming Mars turns the engine-building card game into a digital match.

Beyond the tabletop side, the publisher backs a broad mix of adventure, RPG and simulation titles. Its releases span 2018 to 2025 and come from studios including Flaming Fowl Studios, Lazy Bear Games, Sparrow Night, Odinsoft, Artefacts Studio and Doom Turtle.

Games in the catalogue

The strategy side is led by Gloomhaven and Terraforming Mars, joined by Pathfinder Adventures for card-driven dungeon crawling and Moonsigil Atlas. News Tower puts you in charge of a 1930s newspaper, and Survival: Fountain of Youth is a castaway survival game set across tropical islands.

For adventure and RPG tastes there is Bloomtown: A Different Story, a turn-based RPG in a small American town, alongside the action roguelike Ember Knights, the co-operative tavern chaos of Innchanted and the marble-rolling Amberial Dreams.

Expansions and edition bundles make up a sizeable part of the range, including Gloomhaven: Jaws of the Lion, Gloomhaven: Gold Edition, the Terraforming Mars Collection Bundle and Big Box Promo Pack, and extra content for Survival: Fountain of Youth. Everything here is for PC, with Bloomtown: A Different Story also covered on Xbox One.

How buying works

Most of these titles are Steam keys that you redeem in the Steam client or website to add the game to your library permanently; the help centre explains how to activate a Steam key step by step. News Tower and Bloomtown: A Different Story are also available as gift deliveries, and a handful of titles including Amberial Dreams and Innchanted come as game accounts, which arrive with the game already on it and are signed into rather than redeemed.

Games are sold per region, so check that the region of a key matches the region of the account it will be activated on before redeeming. Downloadable content and expansion packs need the matching base game on the same account.
