See Ma’k Morin’s blog post about Roomans here.
Yesterday I painted 13 that Ma’k converted to “space Roomans” by combining parts of a Ral Partha Rooman with the body of a Reaper science fiction figure. I think the conversion was quite effective.
I cut some of the arms and re-glued them to give a little more variety to the posing. It was a primitive conversion job, but from wargaming distance, they look okay.
Beware space farers when you hear the fear-inspiring battle cry of the Romman marines: ”Roop! Roop! Adoop!”
