Dangerous Seed

Dangerous Seed is a 1989 vertically scrolling shooter video game developed and published by Namco for arcades. 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.
