Dangerous Seed

Dangerous Seed (デンジャラスシード) is a vertical scrolling shooter arcade game that was released by Namco in 1989 only in Japan. In 1990, a Sega Mega Drive version was also developed and released only in Japan.

The player assumed control of three separate ships operated by three separate pilots: Alpha ship is piloted by Yugo Tyrone, Beta ship is piloted by Belle Vogato, and Gamma ship is piloted by Kenny Crawford. Each ship had a different firing pattern that the player could switch between when the ships were formed together as The Moon Diver. Their mission is to quell an alien invasion spanning all of the Milky Way and destroy the alien's headquarters: the Danger Seed.

Gameplay
The player starts with three separate fighters and has to make it through four tubes using the fighters separately. If one gets destroyed, then the next, more powerful ship makes an attempt to get through. If you get to stage 5, the three ships combine into one big ultra combo ship called the Moon Diver which brings massive amounts of sheer firepower. Each ship has shields, but the stages must be completed with one ship. The gameplay is also very similar to that of Dragon Spirit and Phelios.
