This was a fun little side project and design exercise.
I like the story and universe of Halo and was a bit annoyed by some of the armor and helmet designs in Halo 5: Guardians. For a supposed combat exo-suit of Spartan super soldiers, a lot of them vary so wildly that my suspension of disbelief is giving out considering they need some common standards for maintenance and field repair.
Hence this little attempt to reduce the complexity in the designs and getting rid of some of the elements I didn't like while trying to keep the icons of the originals.
