Background & introduction

Endeavor: Deep Sea puts players in charge of independent marine research institutes. The team explores ever deeper waters to observe, understand, and protect the ocean, rather than extract material resources from it.

Specialists, vessels, and action discs limit how the team can work. Each scenario provides its own ocean layout, Impact Board, and scoring goals. Developing attributes, publishing Journals, and completing conservation projects can turn this round’s opportunities into the ability to do more later.

Core rules & scoring

  1. Play six rounds. In each Preparation phase, first recruit one Junior Specialist allowed by your Reputation level, then gain discs according to Inspiration, and finally reclaim discs from Specialists to your Staging Area according to Coordination. Attribute increases gained during these steps affect the steps that follow.

  2. During Activation, players take turns clockwise from the Wave holder, acting or passing. Normally, spend one disc from your Staging Area on an unoccupied Specialist activation circle to use its abilities; Sonar, Conserve, and Journal actions need additional discs. Choose one side of a slash-separated ability; otherwise multiple abilities may be carried out one at a time in your chosen order.

  3. To take an ordinary action in a zone, you need one of your vessels there. Your Technology level limits both travel distance and depth. Move between horizontally or vertically adjacent zones, without crossing empty spaces that have no zone. Only the final destination provides an arrival bonus.

  4. For Sonar, put a disc in the leftmost empty space of the current zone’s sonar track, take its reward, and discover a new zone if instructed. Draw two Ocean boards of the indicated depth and choose one, placing it within the scenario’s layout restrictions and collecting its one-time discovery reward. You may discover a depth your vessels cannot yet travel to.

  5. Diving takes the top Dive token from your zone. When you use it, choose either its Research value or its ability. You may use several on your turn, but can keep at most one at turn end; use extras before finishing. Research is capped at twelve and excess is lost. Conserve pays the site’s Research cost; Journal must match the site’s field icon with a displayed Journal and pay that Journal’s Research cost.

  6. Place Impact rewards on the scenario’s Impact Board, normally in an empty hex indicated by an entry arrow or sharing an edge with any occupied hex, including an opponent’s. The round ends when everyone has passed; a player who passes cannot act again that round. Unless the sixth round has finished, pass the Wave clockwise and begin the next round.

  7. After round six, add the four attribute-track scores, Impact Board points, Journals and tier-five Senior Specialists, and scenario goals. Add remaining Research, including a kept Dive token’s Research value, to the discs still in your Staging Area and score one point per complete group of three. You must meet a goal’s stated criteria to qualify for its leader reward. Qualified players tied for first each receive the first-place reward and no second-place reward is awarded. Highest total wins; tied players share victory.

Rules & gameplay questions

May I recruit a duplicate Specialist, and do they enter on their Senior side?

Duplicates are allowed, but recruits always enter on their Junior side. Resolve any immediate rewards before continuing to Effort and Reassignment.

Can Preparation reclaim discs from Specialists, Journals, and ocean zones alike?

No. Reassignment uses your Coordination level to reclaim discs from Specialists only. A disc in a published Journal’s activation circle remains there until game end, and discs in ocean zones are not Specialist discs either.

Can I collect every arrival bonus along a route through several zones?

No. Travel grants only the final destination’s arrival bonus. A new vessel entering the scenario’s starting zone can receive that zone’s arrival bonus, including your initial vessel during setup.

Does a Dive token give both its Research and its ability?

No. Choose one when using the token. It can be used on the turn you gain it, before or after activating a Specialist, or between actions. Use any tokens beyond one before ending your turn.
