This was really well done. I liked the CG and the integration of the actors into the backdrops. I liked it better than Troops.
While the humorous points were total jabs Spoiler:
Like the briefcase gag, they really took me out of the universe, if only for a brief moment. If they kept it a little more serious, like in the tone of the game Republic Commando, I'd probably have liked it more.
I did like the comment, "Out of the way, tree dodger!"
Looking forward to future chapters.
