NAM-1975 was released on April 26 1990 in Japan.
This is the first game developed for the SNK Neo-Geo MVS hardware
One of NAM-1975's influences was the 1987 Stanley Kubrick film, Full Metal Jacket. There are even some scenes which mirror the film such as the screaming soldier in the intro with the 'Born To Kill' helmet, and a Vietnamese lady with an AK-47 (which is seen near the end of the movie).
NAM-1975 was a blatant plagiarism of TAD Corp's "Cabal
", released in September 1988.
