Endeavor: Deep Sea is a strategy game for PC that places players at the head of an independent research institute tasked with exploring ocean environments and advancing sustainable marine projects. The experience centers on building a capable team of specialists while balancing exploration, research, and conservation goals across a modular board that represents surface and deep-sea zones.
Gameplay
Core play revolves around a worker placement system combined with track advancement on a personal player board. Each round begins with a preparation phase where players recruit specialists from a shared pool, limited by their current reputation level. These specialists provide specific action options once placed with discs from a staging area.
During the activation phase, players take turns performing actions such as travel to move vessels across zones, sonar to reveal new board tiles, dive to collect research tokens from sites, journal to gain points and bonuses, or conserve to place impact markers. Four attribute tracks track progress in reputation, inspiration, coordination, and ingenuity, with higher positions unlocking more vessels, better recruitment options, and increased movement range. Arrival bonuses from zones and dive token effects further shape decisions. Games last six rounds in most cases, after which final scoring tallies points from track positions, impact markers, journal cards, upgraded specialists, and scenario-specific goals.
Game Modes
The game supports three distinct modes that share the same core rules with minor adjustments. Competitive play pits players against each other for the highest individual score after six rounds. Cooperative mode introduces shared goals and setback elements, requiring the group to meet collective thresholds across multiple objectives. Solo mode follows cooperative rules but extends play to seven rounds for a single participant aiming to satisfy the same goal thresholds.
Every session uses one of ten available scenarios, each with its own setup, special rules, impact board configuration, and scoring objectives. These scenarios vary in complexity and emphasize different combinations of actions and end-game priorities.
Scenarios and Progression
Scenarios serve as the main source of variety, dictating initial board layout, bonus conditions, and the three primary scoring goals per mission. Players select from the full set of ten at the start of each game, allowing repeated plays with fresh challenges. Progression feels natural as recruited specialists and advancing tracks open new options for chaining actions efficiently across rounds.
The modular board grows through exploration, creating different layouts each time. Impact placement on the scenario board rewards both individual performance and timing, while journal cards collected during dives add another layer of scoring and occasional special effects.
