Main games

• Contra (Arcade, NES, MSX2, DOS, C64, CPC, ZX) (1987)

  Contra is the first game in the series.^[2]: 4 Many of the series' conventions such as power-ups, two-player cooperative gameplay and the character's light mobility (including somersaults) were already present in this game. The game is composed of traditional side-view stages that scroll either vertically or horizontally, as well as "3D view" stages in which the player moves towards the backgrounds. The NES version is different from the arcade version and has longer stages and numerous other modifications. In Japan, the Famicom version uses the VRC2 chip, which allowed for additional background animation and cut-scenes not included in its North American and European NES counterparts. An MSX2 version was also produced that is drastically different from the other two versions, made by Konami staff members, but not by the original team who made the original Arcade. Several computer versions were done outside Japan, by Ocean in Europe for the C64, CPC and ZX, and by Banana Software in North America for DOS based PCs.

• Super Contra (Arcade, NES, DOS, Amiga) (1987)

  Super Contra replaces the 3D view stages from the original with top-view stages similar to those in Commando or Ikari Warriors. Features unique to the arcade version includes upgradable weapons and the ability to control the character's jumping height. The NES version (retitled Super C for its North American version) has three new stages and a new final boss, but lacks the upgradable weapons from the arcade game. Unlimited Software created DOS and Amiga conversions for the North American market, based on the arcade original.

• Operation C (Game Boy) (1991)

  Operation C is the first Contra game made specifically for a portable platform. Featuring gameplay similar to the NES version of Super C, Operation C also first introduced the "homing gun" power-up.

• Contra III: The Alien Wars (SNES, Game Boy, Game Boy Advance) (1992)

  The series' first entry for a 16-bit game console, Contra III allows the player's character to climb into walls or railings and carry two weapons that can be switched back and forth, as well as smart bombs that kill all on-screen enemies. Many of the stages and bosses made use of the system's Mode 7 graphic effects, including a bike riding stage that ends in a midair battle with the main character riding missiles. The player is now required to rotate their character in the top-view stages to move along with the scenery. Two heavily modified portable ports were produced; a port for the original Game Boy, simply titled Contra: The Alien Wars; and a later Game Boy Advance port, titled Contra Advance: The Alien Wars EX, which replaced the top view stages with levels from Contra: Hard Corps.

• Contra Force (NES) (1992)

  Contra Force combines the run and gun style of the Contra series with a power-up system similar to Gradius. The game is notable for being the first Contra to feature selectable characters with their unique weapon configurations. Contra Force lacks the alien invaders and futuristic environment of previous installments, as the game centers around an elite task force fighting human terrorists in a present-day setting. The game was actually planned as an unrelated game in Japan titled Arc Hound, but it was never officially released there, nor in Europe.

• Contra: Hard Corps (Mega Drive/Genesis) (1994)

  The first Contra game for a Sega platform. Hard Corps also contains selectable characters with unique weapons and abilities and introduces an in-game storyline with branching paths that alter the ending.

• Contra: Legacy of War (PlayStation, Sega Saturn) (1996)

  The first of two Contra titles developed by Appaloosa Interactive, as well as the first attempt to convert the Contra gameplay to 3D and the first game in the series to be played in an isometric perspective. It was originally sold with a pair of anaglyph glasses. It is the first console Contra game to be released in the PAL region with no changes. A Japanese release of Legacy of War was planned, but canceled.

• C: The Contra Adventure (PlayStation) (1998)

  The second Contra game developed by Appaloosa. The gameplay is composed of several side-scrolling and 3D stages, as well as a single overhead stage. It's the only console game in the series to lack a multiplayer mode. C: The Contra Adventure was only released in North America, with no Japanese or European versions.

• Contra: Shattered Soldier (PlayStation 2) (2002)

  Features 2D side-scrolling gameplay with fully polygonal 3D graphics. The player now has a fixed weapon configuration, allowing the character to use one of three weapons. The player can also charge their weapon for a more powerful shot. The game grades the player's performance on each stage and only allows the good ending to those with an above-average rank.

• Neo Contra (PlayStation 2) (2004)

  Most of the game is played in an isometric perspective, but portions are side-scrolling or overhead-behind. The player can now select their weapon configurations, which includes a weapon that locks onto airborne enemies.

• Contra 4 (Nintendo DS) (2007)

  Developed by WayForward Technologies, the gameplay is displayed on two screens and the player's character now has a grappling hook that latches onto railings. The gameplay system is modeled after Contra III: The Alien Wars, with upgradable weapons similar to Super Contra. It also features the return of the 3D view "tunnel" stages from the original Contra. The game has never been released in Europe.

• Contra ReBirth (downloadable for Wii) (2009)

  Developed by M2 and published by Konami for WiiWare,^[3] this 2D side-scrolling game was released in May 2009 in Japan and features Bill Rizer and Genbei Yagyu from Neo Contra fighting off an alien invasion.^[4] It features hand-drawn sprite-based visuals, and has two unlockable characters as well as an unlockable "nightmare mode." With the announcement of the closure of the Nintendo Wii Shop Channel in 2018, and discontinued in 2019, this game is no longer available for purchase or re-download.

• Hard Corps: Uprising (downloadable for PlayStation 3, Xbox 360) (2011)

  The game was developed by Arc System Works and is the first Contra game without the Contra name in the title. It became available on Xbox Live Arcade on February 16, 2011, and was released on the PlayStation Network on March 15, 2011. It is a prequel to the original Contra. The player plays as Colonel Bahamut, the main antagonist from Contra: Hard Corps. Although the game was released with only two different characters to choose from, Konami has released additional characters via DLC.

• Contra: Rogue Corps (Microsoft Windows, Nintendo Switch, PlayStation 4, Xbox One) (2019)

  Developed by Toylogic and published by Konami, Contra: Rogue Corps is a top-down isometric view run and gun game taking place years after Contra III: The Alien Wars, which was released on September 24, 2019.

• Contra: Operation Galuga (Nintendo Switch, PlayStation 4, PlayStation 5, Xbox One, Xbox Series X and Series S, Microsoft Windows) (2024)

  A reimagining of the original game developed by WayForward.

Re-releases

The original arcade versions of Contra and Super Contra were ported to several computer platforms in North America and Europe during the late 1980s and 1990s. In North America, the original Contra and Super Contra (as Super C) were ported to DOS. A version of Super C was also released for the Amiga. Contra was released for DOS,^[11] the Amstrad CPC,^[12] the Commodore 64^[13] and the ZX Spectrum^[14] in Europe under the Gryzor title.

As software emulation became more widespread, the games would be re-released in numerous formats on several platforms, most notable through the Wii's Virtual Console, the Xbox Live Arcade, and the PlayStation Network.^[15]

Storyline and protagonists

Contra, and its initial sequels, are set in the 27th century, and center around two commandos named Bill Rizer (code name Mad Dog) and Lance Bean (code name Scorpion). They are members of a special guerrilla task force codenamed "Contra", who are sent to thwart armies of alien invaders seeking to destroy the Earth. After Contra III: The Alien Wars, the series would deviate from its original premise.

Contra: Hard Corps and its sequels (Legacy of War and C The Contra Adventure) take place after the events of Contra III, and followed several new characters; namely, recurring protagonist Ray Poward. Additionally, Hard Corps would feature human antagonists, rather than aliens. 2011's Hard Corps: Uprising is a prequel to Hard Corps, and is also set twenty years before the events of the original Contra. The game follows a character named "Bahamut", but in an interview with Siliconera, producer Kenji Yamamoto comments that Bahamut may or may not be the same character from the original Hard Corps. Yamamoto would also reveal the reason why the game doesn't use the Contra name in its title was due to how "different" fans regarded Hard Corps from the rest of the series.^[19] Hard Corps and its follow ups have since been considered to be spin-offs from the main series.^[2]: 37

Bill would not return until 2002's Contra: Shattered Soldier; where he became a convicted war criminal sent to fight against his former partner, Lance, who has become a terrorist leader. In the game's sequel, Neo Contra, a cryogenically frozen Bill is ultimately revealed to be a clone of the original Bill Rizer.

Contra 4 was intended to be a direct sequel to Contra III, ignoring the events of previous installments. However, "Mad Dog" and "Scorpion", originally the nicknames given to Bill and Lance in the NES versions of Contra and Super C, were made into separate characters. The game's main antagonist, "Black Viper", is also treated as a new character, despite originally appearing in the North American version of Operation C (which also refers to protagonist Lance as "Scorpion").^[20][21] On the official timeline seen in the "History of Contra" e-book included with the Contra Anniversary Collection, the game is chronology set after the Japanese versions of Operation C and Contra III, but before the events of Hard Corps.^[2]: 37

Contra: Rogue Corps would return to the post-Contra III setting. The game features the return of Kaiser from the latter game, who joins a group of bounty hunters in a place called the "Damned City".^[22]

Contra: Operation Galuga is a reimagining of the original game.

Continuity differences

While the original Japanese version of the early Contra games (specifically Contra, Super Contra and Operation C) were set in the 27th century (in the years 2633, 2634, and 2635 in that order), the American versions of these games omitted this detail and the instruction manuals for these versions implied that the series was set during the present day.^[23] Contra III: The Alien Wars retains its futuristic setting of 2636 for its American release, but the identities of the two player characters, Bill Rizer and Lance Bean (the heroes from the previous installments), were changed to their descendants "Jimbo" and "Sully" in order to retain the continuity of the previous localizations.^[24]

The enemy characters of the earlier games were also named differently in the American versions. In particular, "Red Falcon", originally the name of the terrorist army that was fought by the main characters in the first game (the Red Falcon Organization), became the name of the actual alien entity leader; thus, "Red Falcon" became the name of the final boss fought at the end of Contra, where the player fights both his alien body form and his heart.^[23] In Japan, these are intended to be two different entities: Emperor Demon Dragon God Java and Emperor Demon Evil Heart Gomera Mosking, respectively.^[25][26]

The final boss of Super Contra (or the third to last boss in the NES Super C) and Contra III; is named Emperor Demon Gyaba in the original Japanese versions. Often mistaken as Red Falcon, his American name is referred to as Jagger Froid in the Super C instruction manual.^[27] The American Super C instruction manual also illustrates a common "running" alien enemy from its final stage as Red Falcon.^[27] The alien entity leader known as Red Falcon does not appear as an enemy in the Super Contra or Super C games.

In the Japanese version of Operation C, the antagonist was originally a nameless hostile nation seeking to develop alien-based weapons. This was changed in the North American version to "Black Viper", another alien invader.^[20]

With the release of the American and European versions of Contra: Shattered Soldier, all international Contra releases began to follow the Japanese continuity.

Alternate continuities

Contra Force is a standalone entry that, due to it being originally intended to be separate game altogether, is considered to be non-canon from the rest of the franchise.^{[28][29][30][31]}

Contra ReBirth begins in 2633, but the game's plot primarily takes place in 1973 and incorporates elements of time travel. It has since been considered non-canon, instead taking place in an alternate timeline during a period dubbed "the KONTRA era".^[2]: 37

Probotector

When Konami released the NES version of the original Contra in the PAL region (Europe and Australia) they modified the game by replacing the original main characters and most of the human enemies with robotic counterparts, retitling the game Probotector (a portmanteau of "Robot" and "Protector"). The title referred to the two robotic soldiers, RD-008 and RC-011, who replaced Bill and Lance in this version. This was presumably done due to the German Federal Agency BPjM, which prohibited the sale and advertisement of media deemed too violent to children, including "content which glorifies war".

While the original arcade games, as well as a few computer conversions under the Gryzor title, were released unchanged in Europe, subsequent console installments of the Contra series were released under the Probotector title in Europe. The original Probotector was followed by Probotector II: Return of the Evil Forces for the NES (originally Super Contra or Super C) and Super Probotector: Alien Rebels for the SNES (Contra III: The Alien Wars). The Contra games for the Game Boy (Operation C and the Game Boy version of Alien Wars) and Mega Drive (Contra: Hard Corps) were also released as Probotector titles in Europe. The series would revert to the Contra title in Europe beginning with Contra: Legacy of War for the PlayStation, retaining the human characters. However, Probotector II and Super Probotector were still released for the Wii Virtual Console in Europe and Australia like their original releases, with no "uncensored" versions available. Although Contra 4 was not released in Europe, the "Probotector" character appears in the game as a hidden character.
