From the back of the cover:
THE EDGE OF DISASTER!
Rebellions flare across the Omega sector. The RYN tigers try to break out of their enclave before the Andromedans can destroy them. The Qixa try to escape from their nebula. The Branthodons rebel at oppression by their genocidal Alunda neighbors. And the Bolosco Traders, denied the profits they seek, are hunted by enemies far and wide. On the eve of invasions that will virtually destroy the sector, wars and rebellions create a burning house in which everyone must fight for survival or be destroyed.
The RYN use renewable ceramic armor and transporter-emitter missiles.
The Branthodons use genetically-engineered space dragons for their ships.
The Qixa fight with gauss cannons, ultrawarp missiles, and energy spark rings.
The Bolosco Traders use tractor technology for their primary weapons.
The Koligahr gain caseless anti-matter to blast their foes into oblivion.
The Alunda develop Whipcrack Torpedoes to increase their firepower.
Seven scenarios, 47 new SSDs, 216 Counters, and the Bonnaventure Campaign.
