hand have a look under "Alternative way of making Strong Regenerating Bioplate" if theres anything that doesnt make sense..
I believe I allready have the rollerat queen blood thats used to make Rollerrat Queen Erythrocyte. If nothing else, this is all buyable?? Though its more fun to get the parts and build it from scratch.. :p
