I had a chance to work on the Hel Walker versions of the Raiders based on Yefim Kligerman's original concept. It was really fun as we had a strong base of raiders design and hel walker design already, what I did was to combine them together with the help from my art director Raf Grassetti and lead Dela Longfish. Hope you guys enjoy it!
