Andrew Cook (@AndrewCookDFT) has become quite renowned for his fan made Halo props. Below is his latest creation almost complete.
Click on the pic and you’ll see that he indeed has the hexagonal texture that most Covenant weapons have on them.
Andrew is quite talented. Some prop maker should hire him and then seek out a license with 343/Microsoft to make these for Halo fans/collectors.
He already has an impressive collection of fan made UNSC and Promethean weapons.
