History.dat entry:
NAM-1975 (c) 1990 SNK [Shin Nihon Kikaku].

One or two players take control of 2 machine-gun carrying Vietnam vets who must shoot their way through a number of sideways scrolling, Vietnam-themed levels. the players shoot into the screen and aiming is achieved via the use an on-screen target, which each player directs to lock on to the various enemy troops and vehicles. Players can run and somersault to avoid the incoming enemy fire.

A number of more powerful weapons - such as grenades and flame throwers - are often dropped by the enemy and can be picked up and used. Bonus points are also revealed in this fashion.

Nam-1975 is a blatant plagiarism of TAD Corp's "Cabal", released in September 1988. Cabal is easily the more accomplished of the two games.


Runs on the SNK "Neo-Geo MVS" hardware.
Game ID : NGM-001

Players: 2
Control: 8-way joystick
Buttons: 3
=> [A] Machine gun, [B] Special weapon, [C] Run/Emergency control


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).
