The All Terrain MegaCaliber Six (AT-M6), also known as the Gorilla Walker First Order Heavy Assault Walker or First Order AT-AT, was a mobile heavy artillery walker used by the First Order during their war with the Resistance. Much larger than the All Terrain Armored Transport used by the Galactic Empire, it was the biggest walker in the First Order’s arsenal and featured a megacaliber six cannon mounted to its back,[2] for which it was named.
The All Terrain MegaCaliber Six was first officially revealed on The Star Wars Show on August 23, 2017, along side the First Order Dreadnaught. It was created for the 2017 film Star Wars: Episode VIII The Last Jedi, directed by Rian Johnson, as the First Order variant of the All Terrain Armored Transport of the Galactic Empire, being larger and more stable.
Loved by some, loathed by other fans. Here is the AT-M6 Heavy Assault Walker coming to the movie theaters very shortly. Revell included this one within the set of Star Wars The Last Jedi during Force Friday. There might be a love/hate relation with the design of this walker but one thing is for sure. I am at Target headquarters (Minnesota) and this kits in the area are flying off the shelves. We did share an entry for the A-Wing from the same line of Snap Titeâ„¢ and sure as heck we had a lot of fun building and customizing. That’s what model building is all about.
It took me some 45 minutes to put the kit together. I did not attach the legs because I had plans of painting it. There’s not much detailed reference from the Star Wars The Last Jedi  movie trailers, but enough to take a hint and artistic licence.
PAINTING THE AT-M6 HEAVY ASSAULT WALKER
This was supposed to be a quick build. It is a Snap Tite right? NO! I wanted (as usual to take it for a spin.) I washed all the part with soapy water and after letting the kit dry, I used Mission Models MMP-064 Dark Gull Gray as base color. Then I lighted that color with Mission Models Flat White for some random light spots on those areas of more exposure and create some shades. I sealed the model with Testors DullCote and then started to use pastels for paneling and Ammo Mig Streaks. I used Vallejo ”Escarlata” (red/orange) on the very bottom of the legs because I plan to display it at my local hobby shop on a base. Once everything was finished and no more spraying was to be done, I cracked open the head and added thin strips of clear red sheet from K&S inside the cabin. My goodness, if it turns to be after watching the movie, I can always go back to add an LED to illuminate it.

I know it was a shocker when Lucasfilm unveiled the AT-M6 along with some other ships for the movie. Some call it a ”lazy design”. In all honesty, I was in shock also. But the design on time started to grow on me. Before I received this kit, my desk already had the Hot Wheels version of it. The sound module survived the plastic wash, the paint and the oil washes during the weathering process.
