Armcannon joins the ranks of The OneUps and The Megas in making interpretations of classic video game music rather than strict covers.
Genre vise we are talking metal-prog-glam, and they are mostly in the no-vocals gang, not counting the I'm A Real Sexy American Boy and a few others that have some vocal work.
I find this band very technically capable and they have quite a few classic tunes, so I suggest you check out both their albums on Spotify.
