The back armor is identical, for example.Īdditionally, while you're right that the helmet has retained a basic concept in most of the games, Halo Reach did something very specific with it that I strongly dislike.
There's also more similarities that you can see on other images of Infinite marines we have. I focused almost entirely on the left marine, but if you look up other Reach marines, you'll also see that the shoulders and knees from the right marine appear on Reach marines as well. Look up other marines in the series, they don't really share these exact elements.
The upper shoulder plates, the chest plate, the arm straps, the kneepads, the supplemental leg armor-these are all elements straight from the Reach design with very few differences, and elements relatively unique to the Reach design. Lemme show ya with a good old bunch of colored circles:
I don't know what you mean, there's a ton of carry-overs from the Reach design.
