Periodic Deliveries

Periodic Deliveries is a space shipping and trade game in which you build a growing transportation company. You send goods produced on one planet to planets that demand them, earn money and expand your fleet and network into new solar systems.

Build your trade network

Planets periodically produce goods. To establish a route, choose its destination, set import and export policies, and assign a ship; it then runs automatically, with no maintenance required. Resources never expire, and you can adjust your network as you choose. Trade routes cannot cross, and your company can operate only a limited number of ships, so planning routes and allocating ships and goods becomes more complex as the network grows.

As planets are upgraded, they work faster, produce new and more valuable goods, and gain additional demands. You must meet all of a planet’s demands to raise it to a higher tier. New goods may need to travel through a dense network to distant planets, with ships making multiple stops to collect and deliver cargo.

Research technology

You acquire technology by manufacturing and consuming technology tiers, special goods made from other goods. Producing them is complex, but they give you points to spend in a technology tree, unlocking additional ship designs, company abilities and higher planet levels.
