Discovery mod is a full-scale expansion pack for Freelancer focused on continuing the story started in the vanilla campaign. The mod is used by some of the busiest multiplayer Freelancer servers and has multiplayer features including player owned (and built) bases, jumpdrives, cloaking devices and equipment manufacturing.
This picture shows a Blood Dragon Togo battleship engaging its cloaking device. Feared by the forces of the Kusari Naval Forces, this ancient Togo has been equipped to lurk undetected in the depths of space and strike where it is least expected. Screen provided courtesy of Ryummel.
