Reception

[edit]

Raiden IV has received mixed or average review scores upon its U.S. release, with both IGN and the Official Xbox Magazine scoring it a 6 out of 10. IGN's Eric Brudvig writes: "Though at first glance you might think there are 14 levels in Raiden IV ... there are in fact only seven with the second half of the game merely repeating the first.... UFO Interactive Games went ahead and added insult to injury with its use of downloadable content. After dishing out $40 for the game, you'll find that only one of the three ships on the main menu can be used. The other two must be purchased through Xbox Live". Backlash over the pay to play ships has created controversy at several gaming forums, leading gamers to wonder whether the extra content is worth the price to obtain them.[16]

Raiden IV (雷電IV) is a vertical-scrolling developed and published by , released in on June 7, 2007. As the fourth main installment in the long-running Raiden series, it places players in control of one of three selectable —the Fighting Thunder ME-02, Raiden MK-II, or —equipped with primary weapons like Vulcan cannons and lasers, as well as chargeable sub-weapons such as missiles and plasma beams. The game's sci-fi storyline involves defending from an invasion by the alien Crystals, a crystalline extraterrestrial force seeking to conquer the planet, with stages progressing from rural farmlands and urban skylines to aerial dogfights and outer space battles. Gameplay emphasizes fast-paced, bullet-hell action with medium-density enemy bullet patterns, two-button controls for shooting and bombing, and collectible power-ups that upgrade weapons and enable scoring combos through precise enemy destruction. Raiden IV supports single-player and cooperative modes, featuring five core stages in its arcade version (with up to seven in higher difficulty modes), adjustable difficulty levels, and a branching path system that unlocks additional content based on performance. The title introduced innovations like the "Additional Mode" in console ports, which adds two extra stages and online leaderboards for competitive play. Following its arcade debut, Raiden IV was ported to the on October 2, 2008, in by UFO Interactive, with a North American release in September 2009, including region-free enhancements such as (vertical) screen support and new boss encounters. The 2014 version, subtitled OverKill, revamped scoring mechanics, enemy patterns, and added bonus stages for heightened replayability. The series' modern revival came with Raiden IV x MIKADO remix in 2021 for and 2023 for /5, PC, and Xbox, featuring a remastered by artists like Akira Sato, vertical display options, new battle modes such as Boss Rush, and couch co-op for up to two players. These updates preserved the core arcade intensity while incorporating quality-of-life improvements like customizable controls and gallery modes showcasing concept art, contributing to the game's enduring legacy in the genre.

Gameplay

Mechanics

Raiden IV is a vertical scrolling game that supports single-player or two-player simultaneous cooperative play, where players control fighter ships navigating through enemy waves in a top-down perspective. In the arcade version, the player pilots the Fighting Thunder ME-02 fighter ship; console ports add selectable options including the Raiden MK-II (slower but stronger) and Slave Fairy (faster but weaker), using directional inputs on a for eight-way movement across the screen and dedicated buttons for primary weapon fire, bomb deployment, and activating the Flash Shot—a charged attack mechanic triggered by holding and releasing the shot button after acquiring a sub-weapon, which unleashes a powerful barrage for increased damage and scoring potential. The ship's arsenal includes three primary weapon types, cycled via color-coded power-up orbs (red for Vulcan, blue for , purple for Plasma) and upgraded with each collection up to a maximum level (5 for ME-02 and , 7 for MK-II): the Vulcan cannon delivers a wide spread shot for broad coverage, the fires a straight piercing beam for focused damage, and the Plasma launches homing orbs that track enemies. Secondary weapons, selected via items marked "M" for nuclear missiles, "H" for homing missiles, or "R" for missiles and enhanced up to level 2, provide area-of-effect explosions, target pursuit, or guided strikes, all integrated into the Flash Shot for amplified effects. Defensive options include bombs, which trigger screen-clearing nuclear blasts to eliminate on-screen threats and deal heavy damage to bosses, limited to a stock of three (replenishable via items) with unused bombs granting end-of-stage bonuses; score multipliers are achieved through collecting blue medal chips, which award base points escalating with consecutive chains (starting at 100 points and increasing per streak), and fairies that appear periodically to provide temporary score multipliers, automatic smart bombs during peril, and item dispersal upon collection for rapid acquisition. Boss encounters feature large, multi-phase mechanical foes with distinct weak points exposed during attack patterns, requiring players to dodge bullet waves while targeting vulnerabilities to progress through escalating difficulty; in certain modes like Additional Mode, stage layouts incorporate varied enemy placements to emphasize strategic positioning. The scoring system prioritizes precision and speed, with base points from enemy destruction multiplied by the Flash Shot gauge (ranging from 1.0x to 5.0x based on rapid kills), medal collection chains yielding escalating end-of-stage bonuses up to 30,000 points per streak, and additional multipliers from fairy usage and bomb stock preservation, encouraging aggressive play to maximize totals across loops.

Setting and plot

Raiden IV is set in a futuristic sci-fi within the ongoing Raiden series lore, where Earth faces repeated threats from the alien invaders known as , extraterrestrial entities capable of contaminating and controlling machinery to launch assaults on humanity. These crystalline beings, first introduced in the original Raiden game in 2090, seek to conquer or eradicate life on the planet, having returned multiple times after previous defeats by human forces. The story unfolds in a near-future timeline, emphasizing themes of planetary defense against technological subversion and interstellar warfare, with the Crystals employing advanced, crystal-infused weaponry and structures. In response to the renewed Crystal invasion, the Vanquish Crystal Defense (VCD), a global human coalition formed to counter the threat, deploys the protagonist's vessel: the Fighting Thunder ME-02 Kai, an upgraded variant of the iconic Raiden fighter series designed for high-mobility aerial combat. This advanced ship, equipped for rapid deployment against -controlled forces, represents humanity's reliance on reverse-engineered technology to turn the tide. The narrative is characteristically minimalist for an arcade shooter, conveyed through brief inter-stage text and environmental visuals rather than extensive cutscenes, focusing on the player's role as a VCD pilot in a desperate counteroffensive. The plot follows a linear progression across five stages, beginning with the initial incursion via meteor-like projectiles bombarding rural and urban areas on , escalating to aerial dogfights over cityscapes, industrial zones, and space. The player advances by destroying waves of Crystal-infected enemy , ground installations, and massive boss constructs, ultimately infiltrating and assaulting the heart of the invasion—a colossal Crystal core orbiting or embedded in key strategic points. Success culminates in the repulsion of the current wave, though the lore implies the Crystals' persistent return, updating the series' crystal contamination mechanics with more intricate invasion patterns and defenses. This arcade-style storyline prioritizes action over deep character development, reinforcing the franchise's emphasis on humanity's resilient technological countermeasures against existential alien aggression.

Development

Production history

Raiden IV was developed by Co., Ltd., the Japanese studio formed by former Seibu Kaihatsu employees who acquired the rights to the Raiden franchise and had helmed the series since in 2005. The project was produced by Toshinobu Komazawa, MOSS's CEO and a veteran of the original Raiden games from his time at Seibu Kaihatsu, with planning and development handled entirely in-house by the MOSS team. Key contributors included sound designer and composer Go Sato, who crafted the game's synth-rock soundtrack incorporating remixed elements from prior entries. Following the 2005 release of , MOSS conceptualized to refine the series' formula amid evolving arcade trends, such as hybrid scoring mechanics that blended traditional power-ups with multiplier-based rewards. The core team focused on modernizing visuals using Taito's Type X hardware for brighter 3D graphics and smoother performance, while introducing balance adjustments like an expanded Flash Shot multiplier (up to ×5.0) to enhance accessibility and differentiate from dense patterns. This system rewarded rapid enemy destruction with escalating score bonuses, aiming to appeal to both newcomers and series veterans in arcade settings. Production faced challenges in adapting arcade-centric design for console ports, including the integration of online leaderboards and score attack modes in the version. Early planning for , such as additional playable ships like the Raiden Mk-II and , sparked controversy among players who viewed the paid extras as nickel-and-diming in an otherwise complete arcade conversion. Despite these hurdles, the team prioritized faithful replication of the arcade experience while adding optional enhancements, culminating in the game's 2007 debut.

Location testing

The location testing phase for Raiden IV began with its first public trial on July 22–23, 2006, at the Hey arcade in , running on a II system. This initial build focused on evaluating the core gameplay loop, including the returning Flash Shot mechanic from , early weapon systems, and three difficulty levels: Light, Medium, and Strong. Players tested basic stage progression and scoring elements, providing foundational data on overall playability and pacing. Feedback from this test highlighted enthusiasm for the Flash Shot system's innovative multiplier rewards for rapid enemy destruction, which encouraged aggressive yet precise playstyles, but also pointed to inconsistencies in difficulty progression and scoring sustainability. Developers responded by increasing the Flash Shot multiplier from an initial 2× to 5× in subsequent iterations, enhancing strategic depth and score potential, while reintroducing medal carriers like and Miclus to bolster the medal-based scoring economy. These changes addressed player notes on abrupt difficulty spikes and reward balance, drawing from direct observations and video analysis of test sessions. Additional location tests followed in late 2006 and early 2007 to further refine mechanics. The second round occurred on October 14–16, 2006, at Akihabara Hey and Shinjuku Taito Game World, emphasizing weapon selection and performance equity between single- and two-player modes. By December 27, 2006, the third test expanded to Hi-Tech Sega Shibuya and Shinjuku Game Center Mikado, incorporating tweaks to boss encounter patterns and overall difficulty curves. A fourth round started February 20, 2007, at Shinjuku Game Center Mikado with nationwide guerrilla tests, finalizing adjustments like adding an Original difficulty mode and removing the overly punishing Strong setting. These sessions collectively smoothed transitions from Raiden III's high-speed action toward more tactical, branching-free stage designs with extended loops for replayability. The iterative testing played a pivotal role in development, validating the game's shift to emphasize player agency through balanced risk-reward systems and confirming its readiness for a full arcade launch on June 7, 2007. By integrating empirical player input, the process mitigated production challenges in mechanic equilibrium, ensuring a polished experience that retained the series' intensity while broadening accessibility.

Reception

Critical reviews

Upon its initial console release on in 2008, Raiden IV received mixed reviews from critics, who praised its core shooting mechanics while criticizing its visual presentation and lack of significant evolution from prior entries in the series. awarded the game a 6/10, highlighting the solid, responsive shooting gameplay that appealed to shoot 'em up enthusiasts but lamenting the dated graphics and uninspired level designs that failed to modernize the arcade original effectively. Similarly, gave it a 6/10, commending the replayability offered by multiple ship types and branching paths but faulting the steep difficulty curve that alienated casual players without sufficient accessibility options. The game holds a score of 63/100 based on four reviews. The 2014 PlayStation 3 port, subtitled OverKill in Western markets and featuring enhanced modes and additional content, received generally positive reviews, with a score of 70/100. Critics appreciated the inclusion of OverKill mode, which introduced deeper scoring mechanics through rank-based multipliers and enemy chaining, providing more strategic depth than the base Xbox 360 version, though some noted minor control responsiveness issues when adapting the dual-stick setup to standard controllers. The Mikado remix edition, released in 2021 for and in 2023 for /5, PC, and , garnered generally favorable reception, with a aggregate score of 74/100 across versions. TheXboxHub scored it 3.5/5, praising it as a comprehensive update ideal for series fans due to its compilation of prior DLC and refined visuals, though the core formula remained largely unchanged. Reviews for the 2023 multi-platform version highlighted the remixed , additional boss rush and training modes, and smooth 60 FPS performance, with scores around 7-8/10 from outlets like ZTGD and TheSixthAxis. Common criticisms across releases included the game's adherence to the established Raiden formula without bold innovations, such as novel power-up systems or level variety, and significant backlash against the version's paid DLC for extra ships, which many viewed as an unnecessary barrier to full content access at a high . Within the shoot 'em up community, however, the title earned acclaim for its sophisticated scoring depth, particularly in OverKill mode's and rank systems that rewarded precise playstyles. Mechanics like the Flash Shot were also briefly noted for adding satisfying risk-reward elements to combat.

Commercial performance and legacy

The Xbox 360 port of Raiden IV achieved modest commercial success within the niche genre. The PC version, Raiden IV: OverKill, also saw limited uptake on , reflecting its appeal to dedicated fans. Similarly, the Raiden IV x Mikado remix—an enhanced edition featuring a remixed and additional modes—saw stronger digital sales on platforms like and , though exact figures remain unavailable; its release contributed to renewed series visibility amid limited physical distribution. In the broader market context, Raiden IV played a role in sustaining interest in the shoot 'em up genre during the 2000s, a period when arcade-style titles faced declining popularity due to the rise of first-person shooters and mainstream console trends. Arcade and console ports like this one helped bridge classic mechanics to modern audiences, influencing subsequent shmup compilations and revivals that preserved vertical-scrolling gameplay traditions. The game's legacy endures through its innovative Flash Shot mechanic, which rewards rapid enemy destruction for bonus points, adding a risk-reward layer that emphasizes aggressive tactics over defensive survival. This feature, carried over from earlier entries, has been highlighted in genre overviews for advancing scoring depth in non-bullet hell shmups. Community engagement remains active, with dedicated leaderboards tracking no-miss clears and high scores across arcade and console variants. The 2012 NESiCAxLive arcade update further supports preservation efforts, enabling ongoing play in networked cabinets and fostering informal tournaments among enthusiasts. The 2023 release of the remix cemented Raiden IV as a high point in the series, enhancing accessibility and tying into broader arcade heritage initiatives.
