The Gizureans are legion, with an incredible reproduction rate, along with a ruthless focus on gaining and consuming enough resources to keep their burgeoning populations happy enough to stave off their tendency towards tribal strife. They also have a mysterious past, as the hive mind they once had was broken and a more limited shared consciousness is all that remains (though players who choose to may still play as a Hive Mind).
They engineer their ships through partially organic processes, which allows them to be tougher, but their real focus is in their numbers. Gizureans tend to focus on numbers and tactics based on quantity in space combat, specializing in many smaller ships and large quantities of hive starfighters for their ships, stations and colony defense with the earliest access of any faction to planetary starfighter bases.
While Gizureans themselves are relatively poor scientists, their talent for thoroughly disassembling and reverse engineering anything they find or capture means that it is possible to keep up in the technological race through conquest and salvage.
The history of the Gizureans is connected with that of the Hive threat as well as the ancient enemy known as the Shakturi! The Gizurean storyline will explain the origins of the Hive and why the Gizureans are no longer, by default, a full Hive Mind.
The Gizurean victory conditions encourage numbers, growth and conquest.
