Discovery mod is a full-scale expansion pack for Freelancer focused on continuing the story started in the vanilla campaign via the roleplay-driven multiplayer server an community forums. The mod and community currently host the most active remaining multiplayer experience for Freelancer and the mod introduces many new features including but not limited to new ship classes and types, ship equipment, player owned (and built) bases, jumpdrives, cloaking devices and equipment manufacturing as well as the ability to create, run and maintain player-led factions that shape, contribute and are a part of the ingame roleplay environment. This multiplayer-focused mod allows players to immerse themselves in the Freelancer world some time after the Nomad War from the singleplayer experience.
This is the test station the Discovery member Daedric set up for his tutorial on base building. It's a core 1 PoB, which is the basic deployment structure. To deploy a base, you need a Base Construction Platform (the ship pictured - previously the Heavy Lifter) which is filled with the appropriate commodities. Screen taken by Discovery member Daedric.
