No Belter Left Behind

The umbrella crew-survival cheevo - keep every possible crewmate alive. It's an interdependent chain across all five episodes, so follow a survival checklist; completing it pops alongside Call it Even, Khan's Revenge, Miraculous Maya, Heal Thy Medic and Brother's Reaper. One missed early step (the Ep1 laser crystal, the brig choice) quietly locks a later survival, so get them right or replay from that episode.
