Oh, this is so beautiful. It's impossible not to mentally hear this battle as it would have sounded in the game. I'm glad you decided to shift the setting of your remake. This is definitely going to be my new wallpaper.
Those lovely casing ejectors are far and away my favorite detail, but the parallel trail of rifle casings beside the Marines' footprints are too flavorful to leave unmentioned.
Glad you like it! I did spend a good few minutes just on the ejectors, those were fun to do. Those casings are there to sell the idea that the marines were already firing for a while before the Grizzly's got there.
When I was making this I got an idea to make a scale model of the heavy terradyne, that'd be a nice piece on the shelf...
