Megablast

Megablast (メガブラスト) is a 1989 Horizontal scrolling shooter arcade game released by Taito in Europe and Japan. One or two players could control space fighters assigned to deal with an alien invasion using incredible firepower through eight stages. The game is somewhat parodical as many of the game’s mini-bosses resemble previous Taito game characters and the ending theme consists of a Beethoven song.

Story
Taking place on a future-Earth date, the world has achieved a state of global peace, but only one global problem has risen: a wholesale disappearance of young women around Earth's continents. A top secret planetary protection organization investigated the issue on the strange disappearances and discovered that the women were being abducted by aliens. Said aliens hail from the planet Zancs where a rampant disease has sterilized the entire female populous. Unable to mate with their own kind, the people of Zancs found the perfect reproductive substitutes in the women of Earth and began abducting them to keep the planetary populous steady.

Two fighter pilots - Downson and Bogey - are ordered to rescue the women of Earth, including one of the pilot's significant others, by flying to Zancs and eliminating any threats the inhabitants pose.

Gameplay
The ship was all ready equipped with four Options, each one set to fire in vertical and horizontal positions. The player collected orbs to empower the Option's firing strength and durability; Each Option had to be empowered by collecting the orbs depending on the Option's direction. The player's Extend was set at every 100,000 points.
