is a 1989 vertically scrolling shooter arcade game developed and published by Namco. Controlling one of three different starships, the player is tasked with destroying an alien race known as the Danger Seed before they wipe out all of mankind. Each ship has their own set of weapons and abilities, such as shots that dissolve enemies and target-seeking projectiles, and can sustain multiple hits before being destroyed. The player's ships can also combine into a new ship, the Moon Diver, featuring a stronger shield and additional weapons. It ran on the Namco System 1 hardware.
The game was designed by Yuichiro Shinozaki, a character artist for Namco's own Babylonian Castle Saga franchise, with music composed by Yoshinori Nagumo. Early versions of the game were known as Kristallkern, which remains in-game during the end credits. A conversion for the Sega Mega Drive was released a year later in 1990, which included new features such as additional stages and an arranged soundtrack. Dangerous Seed was met with mixed reviews from critics — although the game was praised for its graphics, fast-paced gameplay and soundtrack, it was criticized for lacking originality and for being unable to stand out among other similar games. Some reviewers stated it was one of the better shoot'em ups released for the Mega Drive.
Gameplay
Dangerous Seed is a vertically scrolling shooter video game. The player controls a fleet of ships — Alpha, Beta and Gamma — as they must wipe out the alien race known as Danger Seed before they destroy all of mankind. Each ship features different attack types; Alpha has a standard shot, Beta has a V-shaped laser weapon, and Gamma has the ability to shoot forwards and backwards. All three also have a health meter that will deplete when they are inflicted with enemy fire, and having one of the ships destroyed will cause the player to take control of the next ship. If all three ships are destroyed, the game will be over. The three ships can also find power capsules by destroying large "Turtle" enemies that upgrade their abilities, such as homing missiles, "ring lasers" that track enemies, and a melt-missile that dissolves enemies when they are hit.
The game spans twelve stages, known as "tubes" in-game, each taking place in planets found in the Solar System. The fifth tube combines the player's ships into a single craft named the Moon Diver, which features all of the weapons and abilities of the three ships and a large health bar. Each tube features a boss fight at the end, which must be destroyed in a certain amount of time before it flees and deducts points from the player's score. Bosses have weak points which must be destroyed before completely defeating it.
Development
Dangerous Seed was released by Namco in December 1989, making it the company's final arcade game of the 1980s. It was designed by Yuichiro Shinozaki, who was a character designer for the Babylonian Castle Saga franchise. The game was originally known as Kristallkern in early prototypes, with the end credits still retaining this name — the credits also hint at a follow-up with a vague "To be continued" message, however a sequel was never released. The soundtrack was composed by Yoshinori Nagumo, which was re-released by Victor Entertainment in 1990. A Sega Mega Drive conversion was released exclusively in Japan on December 18, 1990, adding new features such as additional stages and an arranged soundtrack.
Reception
In Japan, Game Machine listed Dangerous Seed on their January 15, 1990 issue as being the seventeenth most-successful table arcade game of the year. The Mega Drive version in particular was met with mixed reviews, being praised for its colorful graphics, fast-paced gameplay and soundtrack yet criticized for its lack of originality and being unable to stand out among other shooters in the market.
