I think you may need some more tragic music. "Conquest of Paradise" is the soundtrack specially composed by the famous Greek music master Vangelis for the film "1942". But everyone must be familiar with it. It was used in the Hong Kong film "Dark War", and it seems to have been used in "Soldiers Assault". It is very tragic and has the meaning of Kang's death, a bit like some music styles of the former Soviet Union. "Heart War" - Alan Utada Hikaru's Prisoner of Love and Pirates of the Caribbean have some great music, go check it out
