Raiden is a vertical scrolling shoot 'em up released in September 1990 by Seibu Kaihatsu. The first installment in the popular Raiden series, it was Seibu Kaihatsu's hit game.
The year is 2090. Earth suddenly becomes a target for a race of deranged aliens known as Cranassians. Following the invasion, a new cutting-edge weapon, based on one of the destroyed alien starships, the Raiden Supersonic Attack Fighter, is built to save humanity from the clutches of the crazed aliens.
- Vulcan Cannon: The main spread weapon. The more upgraded it is, the greater it spreads, which annihilates enemies on different sides of the screen from one area.
- Ion Laser: Fires straight beams that does twice the damage of the vulcan spread.
- Thermonulear Bomb: Gives a heavy blast, taking out most regular enemies at once and severly damageing bosses, You eventually run out of bombs, but obtain them again by shooting a heavy enemy (not a boss).
- Nuclear missiles: Fires six missiles that go straight (takes 1 sec. to reload).
- Homing missiles: Fires multiple homing missiles at random enemies (0.5 sec. to reload).
When a player comes behind the other player, an array of stars will start to fly across the screen, which has twice the damage of the Vulcan spread. When a player dies, the fragments of the gunned-down fighter becomes projectiles that harm all enemies on-screen.
- Red beacon: Gives the Vulcan firepower to the player who obtains it.
- Blue beacon: Gives the Laser firepower to the player who obtains it.
- M: Gives the Nuclear missile sub-weapon to the player who obtains it.
- H: Gives the Homing missile sub-weapon to the player who obtains it.
- 1-UP: Gives the player who obtains it an extra life stock.
- P: Maximizes the players current weapon sets to full power.
- B: Increases bomb stock by one.
- Medal: Gives a score of 300 points.
- Miclus: Seibu Kaihatsu's dragon mascot appears in Raiden and it's series, giving a score of 3,000.
- Fairy: A small humanoid creature that gives whoever obtains it 10,000 points.
There are 8 stages in the game (note: the Megadrive port features an additional bonus stage, whereas the PC-Engine Super Raiden port adds two more stages for a total of 10). When continuing after the player's defeat, they resume from a predefined checkpoint.
At the end of each stage, player gains stage bonus equals to the number of medals gained in a stage with current life, multiplied by number of bombs player possesses, multiplied by a 1000. If medal or bomb stock is 0, the count is equal to 1 for each affected field for scoring purposes. After defeating the Stage 8 boss, the mission is completed, and player receives 1 million bonus points. Afterwards, it will start back to Stage 1. This time around, enemies shoot faster and at a more rapid rate. After completing the second 8 stages the player is awarded 2 million bonus points, after completing the third 8 stages, the player is awarded 3 million bonus points, and so on. After the tenth 8 stages, the player is awarded 10 million bonus points. However, for the eleventh 8 stages and later, the amount of bonus points is variable (usually between 7-9 million).
The maximum score is 99,999,999. After reaching this score, the player can continue on playing, but the score stays at 99,999,999. After reaching 99,999,999 points, free play is enabled - the credit counter stays at 9 (the maximum number of credits) for all subsequent games until the arcade game is rebooted. This may be a software bug rather than an intentional feature as the sample gameplay sequences prior to starting a game are also disabled after reaching 99,999,999 until the arcade game is rebooted.
