'''''Mega Man 4'''''{{efn|known in Japan as {{Nihongo|'''''Rockman 4: Aratanaru Yabou!!'''''|ロックマン4 {{ruby|新|あら}}たなる{{ruby|野望|やぼう}}!!|Rokkuman 4 Aratanaru Yabou!!|lit. "Rockman 4: A New Ambition!!"}}}} (stylized as '''''Mega Man IV''''')  is a 1991 [[Action game|action]]-[[platformer|platform game]] developed and published by [[Capcom]] for the [[Nintendo Entertainment System]]. It is the fourth installment of the [[Mega Man|original ''Mega Man'' series]] and was originally released in Japan on December 6, 1991. The game was released in North America the following January, and in Europe in August 1993 by [[Nintendo]].

The game's story takes place after the third defeat and supposed death of [[List of Mega Man characters#Dr. Wily|Dr. Wily]] in ''[[Mega Man 3]]'', and features the Earth coming under threat from the mysterious Russian scientist [[List of Mega Man characters#Dr. Cossack|Dr. Cossack]] and his eight "[[List of Mega Man characters#Robot Masters|Robot Masters]]". Fearing the worst, [[List of Mega Man characters#Dr. Light|Dr. Light]] sends [[Mega Man (character)|Mega Man]] to save the world once again. ''Mega Man 4'' carries on the same action and platforming gameplay as the first three games, in which the player completes a series of stages in any order and adds the weapon of each stage's boss to Mega Man's arsenal. One notable added feature is the "New Mega Buster" (often shortened to "Mega Buster"), an upgraded arm cannon that lets the player charge a regular shot into a much more powerful blast. The development team was mindful that this innovation would change the overall feel of the game.

Similarly to its predecessors ''Mega Man 4'' was remade for [[PlayStation (console)|PlayStation]] in Japan. In later years it appeared on [[mobile phone]]s and as part of game compilations, including ''[[Mega Man Anniversary Collection]]''. The [[Video game console emulator#Official use|emulated]] versions were also released through [[PlayStation Network]] and [[Virtual Console]]. The game received positive reviews overall, with critics praising its tried-and-true gameplay formula, but feeling that it wasn't as good or innovative as its predecessors. A sequel, ''[[Mega Man 5]]'', was released in 1992.

==Plot==
''Mega Man 4'' takes place in an unspecified year during the 21st century, described as the year "20XX". One year after the events of ''[[Mega Man 3]]'', a mysterious [[Russians|Russian]] scientist, [[List of Mega Man characters#Dr. Cossack|Dr. Cossack]], unleashes an army of robots with the intention of world domination, much like [[List of Mega Man characters#Dr. Wily|Dr. Wily]] before him. Concerned over the situation, [[List of Mega Man characters#Dr. Light|Dr. Light]] calls upon his own greatest creation, the hero [[Mega Man (character)|Mega Man]], to go after Cossack's [[List of Mega Man characters#Robot Masters|Robot Masters]], who have seized control of eight cities.<ref>''Rockman 4 Aratanaru Yabō!!'' manual, December 1991, [[Capcom]].</ref> He also creates the support robot Eddie and equips Mega Man with the New Mega Buster, an upgrade for his Mega Buster.<ref>{{cite video game|title=Mega Man 4|developer=Capcom|publisher=[[Capcom]]|date=December 1991|platform=Nintendo Entertainment System|quote='''Narrator:''' Dr. Cossack, a mysterious scientist, has invented eight powerful robots and sent them after Mega Man. Mega Man starts for the battle again, this time equipped with the powerful New Mega Buster!!}}</ref>

Upon defeating the eight Robot Masters — Toad Man, Bright Man, Pharaoh Man, Ring Man, Dust Man, Skull Man, Dive Man, and Drill Man — Mega Man makes his way to Cossack's icy fortress. However, in the middle of his battle with Cossack, Mega Man's brother [[List of Mega Man characters#Proto Man|Proto Man]] teleports in with Cossack's daughter, [[List of Mega Man characters#Kalinka|Kalinka]]. The girl begs Mega Man to stop fighting and explained that Dr. Wily had kidnapped her, forcing her father to build an army of robots and antagonize Mega Man as ransom.<ref>{{cite video game|title=Mega Man 4|developer=Capcom|publisher=[[Capcom]]|date=December 1991|platform=Nintendo Entertainment System|quote='''Kalinka:''' Please Mega Man don't!!

Mega Man escapes as the fortress begins to self-destruct, and rides home on the top of a passing train, where he is greeted by Roll and Rush.

==Gameplay==

The protagonist, Mega Man, is able to run, jump, shoot, and climb his way past obstacles and enemies; the game also retains the slide ability which debuted in ''[[Mega Man 3]]''. At the end of each stage is a Robot Master boss.

==Development==
''Mega Man'' series artist [[Keiji Inafune]], credited as "Inafking", stated that the development team had very few problems while working on ''Mega Man 4''.<ref>{{cite journal|journal=CFC Style Fan-Book | volume=3 | author=Inafune, Keiji | year=1997 | title=''Rockman'' 10th Anniversary Celebration Plans | publisher=[[Capcom]] | language=ja | page=24 }}</ref> Inafune designed Dr. Cossack and Kalinka as two new storyline characters for the game. Cossack, who was originally named "Dr. Vice", was made much younger than Dr. Light and Dr. Wily. Inafune also considered giving him [[United States|American]] traits, but decided upon influences from Russia instead.<ref name="MM25"/> Kalinka was created because so many male characters already existed in the series at this point. However, Inafune did not intend for players to compare her to Mega Man's sister [[List of Mega Man characters#Roll|Roll]].<ref name="MM25"/> The idea for Eddie originally came about during the development of ''[[Mega Man 2]]''. Eddie was designed as a supporting character that "would behave like a [[lottery]]", either pleasantly surprising or disappointing the player with the item he gives Mega Man.<ref name="MM25"/>

''Mega Man 4'' was the first game in the series for Hayato Kaji, credited as "K. Hayato", a prominent designer for many later ''Mega Man'' games. Kaji was responsible for the chargeable Mega Buster, a gameplay mechanic that would become a staple of the series.<ref name="MM25"/> "We knew adding a two-level or three-level charge would change the whole flavor of the game in some respects, and we were very mindful of that," Inafune explained.<ref name="MM25"/> The Robot Masters in ''Mega Man 4'' are a result of a design contest for fans held in Japan. With over 70,000 character submissions, the development team spent an extended period of time narrowing them down to only eight bosses.<ref name="MM25"/> According to Kaji, the team was very satisfied with many of the chosen designs and almost no changes were made to their original illustrations. They were so impressed with Skull Man that they scrapped an entire level being created just so they could restart it and devote it to that Robot Master.<ref name="MM25"/> The winning eight contestants of the design contest were each issued a special "golden cartridge" edition of ''Mega Man 4''. As there are only eight of these cartridges in existence, they are extremely rare and fetch a large collector's price today.<ref>{{Cite episode |title=''Ultra Seven'' |series=[[Retro Game Master]] |credits=Arino, Shinya and Suzuki, Sarina |network=[[Fuji Television]] |location=[[Minato, Tokyo]] |airdate=May 2, 2007 |season=7 |number=45 | language=ja}}</ref> The musical score for ''Mega Man 4'' was composed by Minae Fujii, credited as "Ojalin", while the sound programming and sound effects were handled by [[Yasuaki Fujita]], credited as "Bun Bun", who had composed the soundtrack for ''Mega Man 3'' the previous year.<ref>{{cite web | author=Gonazales, Joveth | date=February 5, 2010 | title=Japanese ''Mega Man 10'' Soundtrack Details | url=http://www.capcom-unity.com/jgonzo/blog/2010/02/05/japanese_mega_man_10_soundtrack_details | work=Capcom Unity | publisher=[[Capcom]] | access-date=February 28, 2011 | archive-url=https://web.archive.org/web/20110708114824/http://www.capcom-unity.com/jgonzo/blog/2010/02/05/japanese_mega_man_10_soundtrack_details | archive-date=July 8, 2011 | url-status=live | df=mdy-all }}</ref>

''Mega Man 4'' has received mostly positive critical reviews. Reviews contemporary with the game's release by the [[United States]] magazine ''[[Nintendo Power]]'' and the [[United Kingdom]] publications [[Official Nintendo Magazine|''Nintendo Magazine System'']] and ''[[Total!]]'' all found ''Mega Man 4'' to have high quality graphics, sound, and gameplay.<ref name="nintendomagazinesystem"/><ref name="nprev">{{cite magazine | author=''Nintendo Power'' staff | title=Now Playing| date=January 1992 | issue=32 | pages=100-103 |magazine=[[Nintendo Power]] | publisher=Nintendo of America | location=Redmond, Washington | issn=1041-9551 | url=https://archive.org/details/NintendoPower1988-2004/Nintendo%20Power%20Issue%20032%20%28January%201992%29/page/n107/mode/2up}}</ref><ref name="totalrev"/> However, they also noted very little improvement over previous entries in the series. ''[[GamePro]]'' was satisfied with the lack of changes. "''Mega Man 4'' continues the tradition — crazed robot baddies, good character graphics, great background art and warped, mechanical music," the reviewer said. "When you have a good game, why make radical changes? Capcom sticks to the blueprints in ''Mega Man 4'' — guaranteeing happiness for ''Mega Man'' fans everywhere."<ref name="gameprorev"/> ''Mega Man 4'' made it into [[IGN]]'s "Top 100 NES Games" list at number 95, with staff writer [[Matt Casamassina]] praising its attempt at better narrative and an essentially similar experience to the first three ''Mega Man'' games.<ref>{{cite web | author=Casamassina, Matt | title=95.

Thomas of IGN stated that, as a stand-alone title, the game is one of the best experiences available from the NES library, although not when compared to its superior predecessors.
