Is a vertically scrolling shooter video game originally developed by Seibu Kaihatsu and distributed by Tecmo in Japan on September 1990.
It was the first game in the Raiden series of vertical scrolling shooter arcade games.
The arcade version was also distributed in North America by Fabtek, Taiwan by Liang HWA Electronics, South Korea by IBL Corporation, Hong Kong by Wah Yan Electronics and in a few other countries such as Malaysia, though the publishers in those countries are unknown.
Raiden takes place in the year 2090 where the Earth has suddenly become the target of a deranged alien empire race known as the Cranassians and after the invasion, the World Alliance Military builds a new cutting-edge weapon based on a captured alien craft, the Raiden Supersonic Attack Fighter, as the only hope for humanity to survive.
The game is inspired by other games in the genre such as Capcom's 1942 and Toaplan's Twin Cobra.
In addition to the original arcade version, several ports were released to multiple consoles and computers such as Sega Genesis, Turbo Grafx-16, Super NES, FM Towns, PC Engine Super CD-ROM², Atari Jaguar, MS-DOS, Play Station, Atari Lynx, among others.
Ports for both the Amiga and the Atari Falcon were in development by Imagitec Design but ultimately never released.
Raiden is a vertical scrolling shoot 'em up game consisting of eight stages where the player maneuvers the Raiden fighter craft dodging enemy bullets and destroying enemy robots, buildings, ground targets, and enemy aircraft.
There are bombs and missile power-ups as well as collectable medals that players can collect, which increases the score at the end of each stage.
When the player dies, the fighter's fragments become projectiles that damage enemies.
On occasion an enemy carrier aircraft comes down and destroying it reveals two types of weapon power-ups: The Vulcan and the Laser, which they can be powered-up multiple times, while other times it reveals bombs and missile power-ups, which can be increased multiple times as well and on rare instances an P icon appears, which instantly power-ups the ship to the max.
There's also two types of missile: Napalm and Homing missiles.
