Androida of Heavy Metal managed to build on the frame of the Ulthar Bot a new technically advanced version that possessed a higher AI and a very efficient and fast tactical computer built in.
Built using the extra backpack component form the Sentry Bots pack, Advanced Sentry Bots are exclusively available to the Heavy Metal team and just that little better than 'normal' Sentry Bots. The Sentry Bots/Advanced Sentry Bots are sculpted Jarek Smolka.
I painted this one at the same time as Androida, but opted for less sharp highlighting. I think it came out okay, and I am not unhappy with the result, but I am still working on the techniques I used, so hopefully there remains room for improvement.
