Huragok
Biology
Huragok (Latin Facticius indoles meaning "artificial genius"), are a race of biomechanical sentient beings that were created by the Forerunners to maintain their technology and, in some cases, biological beings. These remarkably helpful and docile pseudo-organisms are exceedingly patient, rarely communicate with other species, and are almost single-mindedly devoted to their work. Huragok are known to exist in two varieties; those that used to serve the Builders, referred to by some individuals as Engineers, and the rarer Lifeworker Huragok, who were designed to repair and maintain biological lifeforms.
History
Huragok were essentially the scientific and engineering backbone of the Covenant and its economy. They fulfilled one of the most important roles within the Covenant, as they bore the responsibility of maintaining the Covenant's machines, managing medical matters, and interacting with Forerunner technology. While it was generally held that only the San'Shyuum were high enough in the Covenant hierarchy to handle and manage Forerunner research and technology, in reality it was the Huragok who must excavate, unlock, and transport Forerunner artifacts—a fact only known to higher-ranked officials and leaders within the Covenant, due to its sensitive nature. The Huragok were also tasked with securely transmitting data between locations.
Huragok Guide
A quick and short guide on how to play Huragok as either the Builder or Lifeworker caste - and effectively at that. Your jobs are mostly support roles, so don't try to get into the middle of combat unless saving someone from death. Luckily, marines won't ALWAYS shoot you because you aren't obligated to just help the covenant, you just should help anyone in the vicinity if they need it. A true neutral of the human covenant war. Don't directly go out of your way to betray your crew.
Builder
Builder Huragok are self explanatory. Your job is to build. When first starting off you may wish to see what command wants done from you and do it. While waiting for stuff to happen, it is a good idea to do something productive. Remember to keep a construction guide open and pistol on macro just in case.
Lifeworker
Lifeworkers are another self explanatory Huragok caste. It's a good idea to keep the medicine and surgery tabs open in your browser just in case.
