Building your crew is key to success in Citizen Sleeper 2, allowing you to tackle a wider range of contracts. This guide details how to recruit every crew member. While most recruitment is straightforward—accepting their offer to join—some involve successful contract completion or specific events. Remember, you can lose crew members through unlucky rolls or miss opportunities entirely.
Note: Due to Citizen Sleeper 2's dynamic nature, please comment if you discover alternative recruitment methods!

Serafin and Bliss are your initial crew members. While Serafin remains with your crew throughout, he's generally unavailable for contracts. Both join automatically; no achievements are tied to their recruitment.

Juni initially joins temporarily on Hexport. To permanently recruit Juni, head to Helion Gate after completing the "Idle Minds" clock at Solheim Records. A cutscene will trigger, followed by a contract. Agree to let Juni rejoin your ship after completing this contract. Recruiting Juni unlocks the "Data Archaeologist" achievement.

Find Yu-Jin on Far Spindle after completing the "Getting Wracked" clock at Gaia's Gyre (requires ordering a wrack four times, costing 16 Cryo). This unlocks a contract with Yu-Jin. Complete the contract to permanently recruit him. Recruiting Yu-Jin unlocks the "The Freelancer" achievement.

During the "Aphelion Beacon" contract, you have the option to leave Yu-Jin behind. Doing so allows you to recruit Luis. Recruiting Luis unlocks the "Signalchaser" achievement.

Meet Kadet on Far Spindle after completing the "Spindle Core" clock at the Spindle Core location. This unlocks a new drive and the Stripline Express location. Complete the new options at Stripline Express, triggering a cutscene. Finally, travel to the Scatteryards to recruit Kadet. Recruiting Kadet unlocks the "The Spindlejack" achievement.

You can recruit either Femi or Nia, but not both. You'll initially meet Nia on Hexport, where you'll also encounter Femi. Femi reappears on Floatsam, offering a contract to ensure Nia's safety. Complete this contract to choose between recruiting Femi (unlocks "Big Brother" achievement) or Nia (unlocks "Little Sister" achievement).

After your first visit to Olivera, a contract will lead you to investigate Flint's disappearance. This will trigger another contract requiring you to set a trap for an enemy. Follow Xander to rescue Flint and then recruit him. Recruiting Flint unlocks the "Fugitive" achievement.
This concludes the guide on recruiting every crew member in Citizen Sleeper 2.
