The engineers of Hawkorp develop the Connection Ray project: a giant transport ship with a robotic arm serving as space mail.

Seeing the failure to properly accumulate profit for its desired purpose, the ship has been remade from space mail to just another transport. A new AI, Sark, was made for the new system proposed by Offworld designers.
Offworld opens "revending machines" in places of high interest, such as stations or their capital at Celestia Alpha, as well as one on Celestia Beta's ground station. These machines accept an item of your choice, scan it, then pack in a box, attach a one-time use FTL drive to the box and send to Connection Ray. Then these boxes can be purchased for an amount of credits depending solely on its size and design without knowing what is inside. The boxes are produced in various sizes and armouring levels.

The Basic Box is, essientially, a box. It contains an object that does not need any sort of advanced containment, e.g. a firework, a handheld firearm, a fitness ball, and so on. Costs 50 credits to purchase.

The Priority box is made for either fragile or valuable objects. Costs 100 credits to purchase.

The Military Box usually contains some weapon that could deal damage to a spaceship. Costs 1000 credits.

This box was created for transporting either biological or volatile objects, and features full armor plating. Costs 1000 credits.

The High Priority box holds very valuable objects. Costs 2000 credits to purchase.
Take note that civilians get about 100-200 credits for usually any object of interest in the revending machine. Objects of no or little interest (e.g. an old boot, a hat, a stun gun) are usually packed in ordinary boxes and are given 20 credits for. In total, Offworld makes more profit off the boxes than what they pay citizens.
Boxes can be purchased by sending a message to Connection Ray and specifying coordinates, box type and amount, e.g. "coordinate volatile 1". The Connection Ray will then grab the closest box of that type in its disposal, attach a one-time use FTL drive to it and send the box to the desired coordinates.
