Open the Expedition 4 tuckbox and remove the components.
Each player should:
• Flip their ocean board to the divided side.
• Take the 1 Crustacean with 1 Fish core discovery tile from their tile bag and place it, undiscovered side up, in the centre zone of their ocean board (1).
• Add the 3 Finless Sole tiles in their colour to their tile bag (2).
• Place 6 Stingray tokens on their ocean board in the positions shown (3).
• Place their ship in any ocean zone and place their submersible on any vertex adjacent to the zone their ship is in (4).
• Shuffle the 12 Shark Location tokens facedown, then place 1 above and 1 below each of the 6 rounds of the round tracker board. Place the round 1 tokens face-up and tokens for rounds 2 – 6 face-down (5).
• Each player should then attach 2 Sharks to their Shark stands and place them next to the regions revealed for round 1 (6).
If the same region is shown on both tokens, move 1 of the Sharks into the next region clockwise.
• Place the Finless Sole and Shark advanced species guides below the core species guides.
• Place the points of interest references close to players.
