One of my favorite Manga series of all time is the Kerberos Saga. Jin Roh the Wolf Brigade is based on it. (An Anime).

They had a few "live action movies" called The Red Spectacles, StrayDog: Kerberos Panzer Cops. The series even had a radio drama I have not had a chance to hear it but aparently it was good.

The killzone helghast characters seem to be based on the gear from Kerberos Saga.

If you haven't heard of this at all before check it out. If you have what did you think of it?
