Raiden IV is an Arcade game that follows up from the events of its precursor, Raiden III. It was developed by the Japanese company Moss Ltd, under the license of Seibu Kaihatsu, and currently in co-operation with Taito. It was released in Japan Arcades on June 7, 2007, and later on Xbox 360 on
October 2, 2008.
The gameplay of Raiden IV is identical to its prior installments, although its level design is different than Raiden III, but it is exactly the same as Raiden II, as the player starts from in-land, over the farms. In later levels the game progresses through a vast cityscape, into the sky, and finally onward to space. The player faces many enemies, powerful stages, and fearless bosses. The Flash Shot System, first introduced in Raiden III, returns in IV. Multipliers are given for destroying enemies that just appeared on screen, if faster players destroy enemies, the higher the bonuses are.
