An action arcade game developed by SNK
that was originally released in 1986 and internationally in 1987. Psycho Soldier
stars Athena Asamiya, a descendant of Princess Athena from SNK's previous game Athena

Psycho Soldier is noteworthy for being the first video game to utilize a vocal track during in-game play, with vocals provided by Japanese pop idol Kaori Shimizu (not to be confused with the Japanese voice actress with the same name
