Trying to remember a movie I saw on sci fi channel.?

This movie was set in a futuristic wwII like war setting with a few factions on earth that come together to destroy this zombie making machine. there was a faction that had somewhat of a german nazi theme with the eagle crest, and there were zombie like creatures dragging people down into this massive machine/factory. it was a really epic movie and i cant remember its name or how to find it.
