Twelve feet tall and bulletproof, a Hunter is not really a single being, but rather a colony of semi sentient worms that develop a mild mental bond when accumulated in great numbers. Given armor as think as some starships, and with a heavy shield and fuel rod cannon on their arms, Hunters fill the role of infantry support vehicle in the Covenant order of battle. The worm colonies which comprise a Hunters physical form are continually growing, and when one becomes too large to fit inside the armored shell, it splits and forms another Hunter, which is why these units are commonly encountered as pairs, or 'bond brothers.' Though the armor of a hunter is nearly impervious to small arms fire, they can still be damaged through unprotected flex points, and are susceptible to heavy weapons fire.
I saved the Hunters for last, as I think they are the most interesting of the Covenant's varied forces. In fact, they are what got me interested in Halo in the first place, all of those years ago. I think I am going to use some kind of game mechanic to make them vulnerable to 'critical hits' to represent hitting a gap in their armor. Thanks for reading! Until next time.
