Ahh, yes. The Infamous Saber Scorpion. Everyone knows him, He's like a LEGO® celebrity. Seriously though, you gotta give the guy credit. He has made some of the best Halo MOCs out there, the most famous being the warthog. Yes, I did 'copy' his Mongoose, but this is simply for completionist and replications sake. I wanted a full UNSC vehicle lineup, and his, you have to admit, was pretty easy to just look at and build.
I can't remember completely if there was much difference on mine from his, aside from the color.
One thing about the Halo Reach mongoose: Ever since first saw it, i was disappointed. I really liked the look of the Halo 3 one alot more than Reach. I dunno, just thought the new one was to much like an actual ATV. Hm. Whatever.
