From the introduction:
The following is a module designed for 5-8 characters with approximately 20,000 experience and 50,000 credits. The ideal party should consist of: 1 Orion, 1 Zen Rigeln, 1 Python Lizard, 1 Cizerak, and 1 Aedronian or Chatelian. They will have to not only be ready for battle, but be able to handle the miscellaneous challenges of life.
...
They start out in Benka, a mountainous town on Planet Daeyrieen (Hex 1437 of No Man's Land). The town was recently captured by the capitalist Ptuzma, who are fighting the communist group, the Thalin, in a civil war. The rag-tag Ptzuma army, although winning, is unable to advance across a river due to the presence of a Thalin hopper, so they contacted SSDC. SSDC agreed to send mercenaries in return for mining contracts. The party's mission is to capture the hopper. If unable to do so, the party should sabotage or destroy it. The Ptzuma know that sending a crew of adventurers is cheaper then hiring a spacecraft to bomb the site from space - mercs are paid only if they are successful.
