Alien Sub Construction
|Each vessel has a chameleon-like structure, carefully modelled on sea creatures, and constructed of Aqua Plastics. Each submarine functions as an organism: crew and craft in harmony. Most of these systems can be replicated and a hybrid technology can be evolved to allow us to move up to the same technological level.||
Alien Sub Construction modules can be obtained by recovering the modules pictured in the Magnetic Navigation in-game UFOpedia entry (as pictured above). They can be sold for $20,000 each.
There's a research bug where finishing research of the prerequisite technologies (Zrbite and Transmission Resolver) without getting a sample prevents research of this item in the future, making the game unwinnable.
