Wait what does spikes on spikes mean?
Perhaps they are simply a negative?
Marine with spikes = 1 x -1 = -1 (evil)
Marine with spikes on spikes = 1 x (-1 x -1) = 1 x 1 = 1 (good)
But put spikes on the spikes on the spikes, then we're back to Chaos.
Sick model, BTW. I'd look forward to seeing them around.
