Just like my Sangheili officer I shall upload a WIP stage of what I'm working on. Once again I've decided to work on what the Vadam loyal faction would appear as in Halo 4 in my eyes.
Once again they are a fusion of the Mdama Faction's appearance with the original trilogy's covenant appearance. One thing I did do was ditch the Halo 4 physique of the grunt and jackal.
The Grunts(unggoy) are arthropods meaning they are related to centipedes and millipedes. In Halo 4 it seems as though 343 ditched this fact and turned them into a reptilian looking race with the scales and toe nails on them. Although I do like the way their armor looks although they were missing the abdomen attachments to keep the methane tank strapped onto them.
The Jackals(Kig-Yar) were also turned reptilian in Halo 4. Their entire skull structure was changed with 343 ditching the avian skull with a more Zilla 1998 type of head with large teeth. I definitely did not like that drastic change. So I mixed the 2 head styles into 1. Keeping the bird skull they've had since Halo 2 but making it slightly more reptilian look with the jaws.
