Raiden IV

Raiden IV, the seventh full game in the Raiden franchise, was developed by MOSS and was first released on June 7, 2007 in arcades.

Raiden IV is considered to have refined the ideas that Raiden III introduced to the series. Raiden III used 3D graphics instead of sprites; the ship had smaller hitbox; and the bomb deployed instantly instead of after a delay. All these changes were carried over to Raiden IV.

Two significant updates were made to the game in later releases. The Xbox 360 port, released in Japan on October 2, 2008, added two additional stages playable in the “Xbox 360 Mode”. This was renamed Additional Mode in later releases, distinct from the Arcade Mode in which only the original five stages are played.

In April/May 2014, Raiden IV: Overkill was released worldwide for the PS3, which featured Overkill Mode. This mode featured an entirely new scoring system and added two new bonus stages, bringing the total stage count to nine. Enemy patterns were also adjusted.

Gameplay Overview

Raiden IV’s gameplay is characterized by medium quantities of bullets, fast bullet-speeds, an absence of static obstacles, and a multiple-weapon power-up system. This puts it in line with the style of previous game in the series as well as traditional vertical arcade shmups of the early 90s, where the Raiden series originated.

Controls

---

Raiden IV has two-button controls with autofire by default.

• A: Fire
• B: Bomb

Sub Weapon Charge Shot: After a sub weapon (ie. missile) has been obtained, releasing the fire button will charge your ship. Firing after a few seconds will release a larger barrage of your missiles. Each missile that hits will score additional points.

Ships

---

The arcade release had only one playable ship (Fighting Thunder ME-02).

For the Xbox 360 release, two additional characters were made available as DLC. Raiden MK-II is the ship from Raiden II; Fairy was first seen in the original Raiden as a point-scoring item first, now turned into a playable character.

Later releases, for PS3 and PC, made all three ships available in the base game.

Enemy Destruction Points / Flast Shot System

Each enemy has a base point value. For example, the first enemy you meeet is a small ship with a base value of 1,000 points. Medium size ships are [usually^?] 10,000 points, and bosses are 100,000 points.

When an enemy is destroyed, a multiplier is applied to the base value based on how quickly you killed the enemy. The maximum multiplier is x5.0, and decreases the longer the foe is on the screen. The rate of decrease depends on the enemy.^?

The multiplier appears on top of large enemies after you kill them, and to the side of th screen when killing small enemies.
