Maybe a little premature, but here is my work in progress for a Space Marines Army List. It is hardly close to being finished, but please feel free to edit it. I haven't even had a chance to play a game of Warpath, but I am dying to use my Space Marines for something else other than 40k.
I really want to see what Mantic comes up with for their miniature range for Warpath. If they go by their army lists, it looks like there will be plenty of variation, including at least a couple vehicles and one aircraft per army. The inclusion of air units (along with they way they work) surprised me.
