Crew Expendable

A campaign supplement for Cepheus Engine and the HOSTILE setting, focused on blue-collar space truckers conducting routine interstellar haulage. Players crew the Harbinger, a 1,000-ton multipurpose freighter, manage shipboard tasks, and fulfill cargo contracts by delivering goods to specific destinations before deadlines. The supplement includes charter-line companies, starmaps, 36 non-player crew members, haulage rules, crew tasks, and tables for generating contracts, random events, encounters, and mishaps. It supports group roleplaying sessions and solo campaigns when used with SOLO.
