STORY
In the year 2067, most militaries of the various countries still present on the globe were using robot infantry, automated drones, and human-controlled war machines, commonly referred to as "mechs." These mechs were immensely powerful, as they could besiege a fort for days or fend off an entire battalion of enemy soldiers without any help. This particular model, the Atlas-6, was extremely well-equipped with weapons, armor, and even a pair of jets for short flight. It had a crew of 5 (1 commander/driver, 2 exterior weapons controllers, 1 medic, and 1 mechanic), all of whom were elite soldiers, often with cybernetic enhancements.
EXPLANATION
I did this build about a week ago; however, I was out of town, so I couldn't upload it. It is now ready for download though. I tried to incorporate as much detail into this build as possible. There are many things I could do better, but I would rather post it now than later. It was heavily inspired by this image (though obviously my version is way bigger):

I also used this Reddit post as a source of inspiration to figure out how to build some aspects:
