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, and is noteworthy for being the first video game with a vocal in-game soundtrack.
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). This was achieved by creating a JAMMA board that was much larger than usual, and consists of three PCB boards hardwired together and sandwiched on top of each other inside the game cabinet. Her song made Athena one of the earliest video game idols in Japan. Both the Japanese and English-language versions of the game have different vocals for the main song.
The Japanese version of the song was released as a single in 1987 on a special cassette that was available only to those who purchased the Nintendo Famicom version of Athena in Japanese retail stores. The cassette also included a special vocal version of the ending theme.
Athena and Kensou would go on to be far better known as standards in The King of Fighters.
Not to be confused with Sociopathic Soldier.
Psycho Solider has examples of:
- Action Girl: Athena
- American Kirby Is Hardcore: The European and American covers and flyers fit this trope to a T. Here's the art◊.
- Animal Motifs: Athena's motif is the phoenix and Kensou's motif is the dragon.
- Autoscrolling Level: The whole game, which pauses at each boss wall.
- Big Bad: "Shigu Do Dabide" (however the Hell you wanna translate that — the last word is exactly like the Japanese rendition of "David"), the Final Boss and apparent leader of the Shiguma.
- Big Creepy-Crawlies: The Zeel species, massive blue bugs that wander around. The first boss is a swarm of their strongest form infesting a building, the Zeel Zebub.
- Butt-Monkey: Downplayed with Kensou, who after any long drop will inevitably land flat on his face.
- Direct Continuous Levels: After defeating each boss, you go through a very short area at the back filled with breakable walls and power-ups before a drop down that seamlessly segues into the beginning of the next level.
- Energy Ball: The signature Power-Up of the game, where Athena and Kensou can collect up to four psycho balls to create an Orbiting Particle Shield, all of which change color and size according to their personal energy level. (They'd both go on to these Psycho Balls in The King of Fighters tournaments).
- Evolution Power-Up: There's an item that allows you to boost all the enemies on-screen to their next level, with new attacks and attack patterns. There's another one that allows you to level them down as well.
- Gratuitous English: The Japanese version of Psycho Soldier.
- Idol Singer: Athena. Kensou appears to be her lead guitarist.
- Image Song: Psycho Soldier.
- Joshikousei: Athena.
- Notable Original Music: The Psycho Soldier theme is a partly an Expository Theme Tune about several of the game's special moves and techniques and partly an Image Song about Athena (the English version is almost purely Image Song). This song would later become the Bootstrapped Theme for Team Psycho Soldier in The King of Fighters and for Athena herself in other spinoff games.
- Power-Up: A dozen of 'em, which was one of the distinguishing factors of the game.
- Psychic Powers: The basis of their gameplay.
- Sealed Evil in a Can: The "Shiguma" (literal translation "Corpse Fool Demons"), who were sealed away in the bowels of the earth until somebody accidentally let them out.
- Sudden Musical Ending: Tne credits have Athena and Kensou putting on a concert atop a pile of rubble, with Athena singing the game's main theme, while Kensou rocks out on guitar. There is also one of the game's enemies dancing along, for some reason.
- Suddenly Voiced: This game is notable for including the first known example of a full song recording.
- They Look Like Us Now: Downplayed with the Duff-kun, trenchcoat-bedecked zombies with glowing eyes that wander around. Upon being defeated they may reveal themselves to be a disguise for another type of monster.
- You Gotta Have Blue Hair: Athena has pink hair. If The King of Fighters is to be trusted on this point, she dyes it.
