Made in Garry's Mod and edited in Photoshop. Scene is based on Season 10: Episode 10 of Red vs. Blue, which was awesome and I recommend you watch if you haven't already. The right-most Spartan is a hologram, if my representation wasn't... representative enough. I just realized that the description had said "left-most" at first, which is entirely incorrect. It was pointed out in the comments but I didn't really interpret it correctly until I looked back at it a week later.
Very cool and very well done
You mean the right most is the hologram?
