DoDonPachi DaiOuJou
Gameplay. DaiOuJou follows the conventions of the previous game with only a few changes. The chaining system is intact and works in much the same way. Causing an enemy to explode fills a meter, and every enemy destroyed before the meter depletes adds to the current chain and again refills the meter. Holding the laser weapon over a large enemy will hold the meter steady and slowly accumulate hits. In this way it is possible to create a single chain out of any of the 5 stages. The controls in DaiOuJou are identical to the previous games in  the series, and the same shot-laser dynamic as seen in "Donpachi" and "Dodonpachi" are also present, with spread bombs and laser bombs also making a return. However, there are only 2 ships, a narrow shot ship (Type-A) and a wide shot ship (Type-B). In addition, the game introduces Element Dolls, which will power up the player's weapons. The element dolls are: Introduced in this game and carried on in later entries is the Hyper system. By gaining large combos, attacking enemies at close range, and collecting bee medals while a large combo is active (Bee medals  now give score based on how large of a combo is racked up), you build up a hyper meter at the top of the screen. When the meter fills up, a hyper powerup drops from the bottom of the screen. Activating the hyper will cancel all bullets currently onscreen and increases the firepower of your shot and laser. Hypers also increase the rate of which combos are built up, as small enemies will give more hits on the combo gauge, larger enemies will add to the current combo chain much faster, and combos on bosses build up at a much  faster rate. In addition, if a hyper meter is filled during a boss fight, all bullets on screen are cancelled and turned into score bonuses. Plot. After the events of Dodonpachi, in which the pilot stops Colonel Schwarlitz Longhener's plan to annihilate humanity, the remains of the Donpachi Corps are sealed away in the moon, never to be heard from again. 1000 years later, the robotic army, led by Hibachi, have reawakened and are slowly rebuilding itself in order to wipe out humanity again, taking the defenseless moon colony of Lunapolis. The world quickly resurrects the Donpachi Corps, and  aided by Element Dolls, sentient androids meant to increase a ship's power, are deployed on the moon to destroy Hibachi's army. Depending on the element doll the player chose at the beginning of the game, the ending will differ upon defeating Hibachi; Development. Black Label. This variant was a limited edition release. The arcade board includes the original and Black Label games, which can be selected during boot time. The Black Label game can be identified by the black title screen. After the release of the Black label, the original version is called as White Label, particularly for  clarification. A prototype export/overseas version of the Black Label edition named DoDonPachi III was discovered in 2016. Music. The music tracks are puns of shooting game companies. Mukei, Toua, Takimi, Torejya, Saikyou, Seibu, Sakusetsu, Taitou, Raijin, and Awaremu are named after NMK, Toaplan, Takumi Corporation, Treasure, Psikyo, Seibu Kaihatsu, Success Corporation, Taito Corporation, 8ing/Raizing, and Irem respectively. As often pointed out by fans, Manabu Namiki confirmed that the tracks from the game are the shooting game companies stated above he wanted to show respect for. Graphics. With Junya Inoue still a graphical designer, the serene steampunk world of  Progear has been replaced with hard sci-fi. The graphic style, especially the ships were drawn so as to resemble the original Dodonpachi. Bullets are drawn in blue and pink, and many of the backgrounds are deliberately flat so as not to distract from the on-screen action. Releases. PlayStation 2 release. This version added the following modes/features: Death Label mode sets the player against a boss rush, with maximum firepower at all times and a full stock of Hyper granted before each boss. Death Label's difficulty is roughly equivalent to that of the normal game's second  loop, with a number of alterations made to the bosses and their attack pattern. The most notable change is made at the final boss fight of Death Label, where the player faces two Hibachis simultaneously. According to top players, this is the most difficult iteration in the DoDonPachi series taking 7 years (from 2003 until 2010-09-18) to clear. Tamashii. This edition is aimed at the Taiwan-Chinese market and some in-game text has been translated in Chinese. It features an easy mode for beginners (not Black Label). It was published by IGS on April 20, 2010. Black  Label EXTRA release. The 2008-03-07 issue of Famitsu Weekly magazine reported that 5pb. Inc.'s 5pb.Games Division #2 would bring this game to the Xbox 360 platform as an Xbox Live Arcade title. However, 5pb representative Masaki Sakari claimed that Microsoft rejected 5pb's proposals and 'decided to cut down faithful arcade ports.'. 5pb considered releasing Black Label and Ketsui on a retail DVD instead. On 2008-09-26, Famitsu announced the official title of the Xbox 360 version of the game, , scheduled for a release on Christmas Day of 2008. The port includes the original and  Black Label editions of the game, as well as online score ranking, replay saving, enhanced graphics, and Xbox Live Marketplace content. There is an Xbox 360 original mode for beginners named the "X Mode", where a new Element Doll named Piper is introduced. The pre-order also includes a guidebook. "Arcade mode - Old Version -" is a port of the original "White Label" arcade release. "Arcade mode - New Version -" is a port of the newer "Black Label" arcade release. The X Mode features a 1-loop, 5-stage layout with a new game system. The game's music can be changed  from Mono (from the arcade), Stereo, or X Mode, which features rearranged music. Xbox achievements feature 50 categories for 1,000 points in total. The player can get extra credits, X mode, and unlock Config EX options that alter gameplay mechanics by playing the game for a specific amount of time or earning achievement points. The Xbox 360 version was plagued at released with bugs and problems that rendered the game highly inaccurate and glitchy. It was eventually found that 5pb had, without permission, lifted the source code from the PS2 version of the game and slotted it in for the  360 version while making adjustments as needed. Patches were eventually made with Cave and Microsoft stepping in to aid the patching process. Reception.
