I just love war horror! This little subgenre of horror is related to movies happening in WWII, WWI or other wars, or are related to those wars. This little movie is so great that I watched it already three times since it is out ten years ago. Well, a group of mercenaries discovers abandoned mine in which Japanese general Yamashita supposedly hid gold. But, as things go in such movies, there is no gold and the mercenaries and scientists deal with infamous Japanese Unit 731 instead, For those who don´t know, Unit 731 was a sinister Japanese division which did experiments on humans and killed a lot of prisoners of war, especially in the town of Harbin in Manchuria. Well, action here is superb, especially when those Japanese Imperial Guard soldiers step into story. There are couple of great gore scenes, ending leaves place for a sequel which fortunately or less fortunately never came. My heartily recommendation for this one. Directed by Steven Sheil(Mum & Dad).
