What are debri for?

Debris are a very useful resource. They can be recycled and transformed into credits.

To recycle you need to build the Recycler Ship or Heavy Recycler Ship.

Those ships can recycle 10 and 15 debri hourly (on the half-hour) respectively.

The Recycler ship engines use aerospike technology, so it can't travel to other galaxies without a Space Gate.

The Heavy unit use hyperdrive engine, so it can reach other galaxies by itself.
