History After publishing Endeavor in 2009, New Zealanders Carl de Visser and Jarratt Gray had set towards creating another board game built on the foundations of Endeavor. De Visser and Gray designed Endeavor: Deep Sea for one and a half years. A Kickstarter campaign for the game was launched in 2023 by the game's publishers, Burnt Island Games and Grand Gamers Guild. Endeavor: Deep Sea was published in 2024.
In 2026, Endeavor: Deep Sea was the featured game at Wellycon in Wellington, New Zealand.
Gameplay
Players represent an institute of oceanographers doing research and conservation work. Players can compete competitively, cooperatively, or solo. By heading an independent research institute, players have the goal of developing sustainable projects and preserving the balance of marine life. The gameplay includes recruiting a field of experts and using their abilities to explore new locations, researching dive sites, publish ecological papers, and launching conservation efforts.
Across six rounds in the competitive and cooperative modes, players must lead their marine life specialists by making them travel, sonar, dive, conserve or journal in order to score points. In the solo mode, the number of rounds extends to seven.
Endeavor: Deep Sea has 10 different missions for players to elect from in any of the three player modes.

Andrea Champagne of Board Game Quest rated Endeavor: Deep Sea 5 out of 5 stars, noting it was "definitely worthy of being Kennerspiel des Jahres". Champagne praised the game for pulling everything together into something that is "near-perfect whole; the art, the theme, the thematically driven actions." She praised the iconography, theme guides, and how the game can be played in every iteration (competitive, co-operative, and solo) with the same ruleset.
Dan Hinkin of Gaming Trend rated the game 95 out of 100 praising it for its easy to pick up rules which lead to "more strategic gameplay the more you get the game to the table." He praised the replayability with the game having 10 different missions available as well as multiple game modes.
