Zombies in siberia

I had this funny idea about a comic that would be based in the siberia during the russian civil war 1917-1922. Admiral Kolchak and his siberian white army were fighting a desperate fight agains the bolshevic onslaugh when suddenly the dead started to crawl under the snow and feast on the living. War between two armies turned to everyone´s fight for survival. Only way out from the hell is through trans-siberian railway, but the zech-legion who controls the railway won´t sell their tickets cheaply...
