Dangerous Seed (デンジャラスシード) is a 1989 arcade shoot-'em-up by Namco ported to the Sega Mega Drive in 1990. Both versions were released exclusively in Japan.

Story

Alpha, Beta, and Gamma

The Moon Diver is a ship consisting of three sub-ships, sometimes called wings: Alpha, Beta, and Gamma. These ships are tasked with destroying an alien race known as the Danger Seed before they wipe out all of mankind.

Gameplay

The game is a vertically scrolling shoot-'em-up. The player commands a fleet of three spaceships: Alpha, Beta, and Gamma. The player initially starts with only Alpha but acquires the other two ships in the early stages of the game. When the player has more than one ship, they combine into a single ship. The pattern of the weapon fire is affected by which ships are in this formation and which ship is in the lead.

The ship moves in any direction using the D-Pad. It fires its main weapon with , which can be held for rapid-fire. The ship fires a bomb with . Bombs are limited in supply and different for each ship. When there is more than one ship, the player can change the formation with , which changes the lead ship and the weapon patterns. There are three different weapons, which are changed by collecting items. Collecting the same item as the equipped weapon upgrades the weapon level, up to three times, but collecting a different item keeps the weapon level the same.

Each ship has a health meter with three hit points. The topmost ship loses a hit point when the player is hit by enemy fire; a ship is destroyed if it runs out of hit points, which affects the formation of the remaining ships. Formations of fewer ships are less powerful. If every ship is destroyed, the player loses a life but starts the stage over with every ship as long as there are extra lives remaining. The game ends if the player runs out of lives.

There are three selectable difficulty levels (Digest, Easy, Normal, and Hard). Digest mode only plays stages 4, 5, 9, and 12, which starts the player with all three ships. Easy mode only plays stages 2, 4, 5, 7, 8, 9, 10, and 12. Normal and Hard mode play all twelve stages; completing the game on either difficulty gives a cheat code for a hidden Expert mode. Stages 6 and 7 vary depending on whether the player defeats the boss of the previous stage quickly enough.

Versions

Dangerous Seed began life as a Namco System 1 arcade title, and received numerous cutbacks during its transition to Mega Drive hardware. Graphics were simplified across the board, with less detailed stages and simpler cutscenes. Bosses no longer split into pieces when taking damage, and fewer objects are drawn on screen during gameplay. Curiously the colour schemes were changed as well, and horizontal scrolling was removed.

To compensate, the Mega Drive version features additional stages (and extends the arcade levels) and three weapon types (normal, wave, and laser). and the soundtrack was remixed, becoming more upbeat in the process.
