Discovery is a full-scale expansion modification for Freelancer, replacing the single-player campaign with a player-driven online narrative and adding 97 new star systems, 255 ships, hundreds of weapons and equipment types, new factions, new NPC encounters, and its own evolving storyline. The economy has been rebuilt around realistic commodity chains — harvesting, refining, manufacturing, and retail — with enough trade and smuggling opportunities to sustain dedicated haulers. NPCs have been updated to carry better weapons but appear in smaller, more dangerous patrols rather than large disposable swarms. Version 4.87 focused on significant storyline advancement and roleplay infrastructure, including reworked Light Fighter balance, new ship models, and plugin additions such as Player Bases, Jump Drives, and Cloaking Devices.
