Gameplay and design
The home console version spans eight levels, with pacing alternating among several level types. Standard side-scrolling stages focus on running and gunning, while waterfall stages scroll upward, and base stages employ a pseudo-3D perspective with the character facing away from the screen, moving into the background. These three modes rotate, shifting the flow between horizontal, vertical, and depth-oriented movement, preventing monotony. In side-view stages, the character can run, perform forward somersaults, crouch, and shoot in eight directions. Aiming and movement share the same controls, eliminating the need to switch shooting directions separately; players can fire at any angle while running or jumping. This design naturally integrates movement and attack, requiring players to adjust their aim while constantly on the move.
As a rule, a single hit or contact with a hazard typically costs a life. The North American manual specifies three starting lives, with an extra life awarded after each level, and allows up to three continues. The one-hit-death rule makes mistakes costly, and the limited continues further reduce margin for error. Players must memorize enemy spawn points and bullet patterns to complete the game without continuing. Weapon capsules and fixed turrets offer weapon changes and upgrades, with the spread gun's fan-shaped barrage becoming the most iconic pickup. However, the one-hit-death rule means that a hard-earned upgraded weapon can be lost instantly, making weapon choice and risk management part of the rhythm.
Two-player mode allows Bill Rizer and Lance Bean to play simultaneously, sharing one screen, so scroll speed and position become a shared concern, especially in upward-scrolling waterfall stages where the shared screen demands coordination. The home console version's loop consists of short waves of enemies, readable bullet patterns, sudden boss battles, and quick restarts, making memorization and execution part of the challenge while still requiring quick reflexes. This design lets players gradually master the rhythm through repeated attempts.
The arcade version of "Contra" used a vertical screen, while the home console versions were redesigned for the horizontal television format of the FC and NES. This change not only altered the screen orientation but also prompted a significant expansion of the map size and the addition of original content, rather than simply shrinking the arcade screen. The arcade original featured alternating side-scrolling, upward movement, and pseudo-3D sequences, with large fortress scenes and boss battles as its main visual elements. This diverse level design was distinctive among arcade games of the time, offering players a rich visual experience.
The home version retained the arcade's excitement while adding larger level maps and more varied enemy attack patterns. Konami officially stated that this adaptation was not merely a matter of shrinking the arcade screen but involved expanding content to let players experience tension and challenge close to the arcade on the FC and NES. The difficulty is built on the "one-hit-death" rule: whether touched by an enemy, hit by a bullet, or falling into a pit, a life is lost. The US manual gives three starting lives, awards one per level, and allows up to three continues. This design encourages repeated attempts in short bursts, but each failure stems from clearly visible bullet patterns or terrain, so the challenge, though harsh, remains readable.
Weapon capsules and fixed turrets appear periodically in levels, offering weapon changes and upgrades. The spread gun, with its wide barrage, is the most recognizable pickup, but the one-hit-death rule means that once hit, the upgraded weapon is immediately lost. Players must weigh whether to risk picking it up or plan their firepower configuration from a safe position, making this trade-off a core strategic element. Two-player mode allows Bill Rizer and Lance Bean to act simultaneously, but they share the same screen, so scroll speed and character position become a common concern. Especially in upward-scrolling waterfall stages, the screen advances faster, and either player lagging behind or rushing ahead can leave the teammate in danger out of view. Players must constantly communicate or coordinate to ensure both remain within supporting range.
Background and release
Konami released the arcade version of "Contra" in 1987, with the Japanese home console version following on February 9, 1988, and the North American NES version later that same year. The home console version was not a simple port but was redesigned for the horizontal television format, expanding the map size and adding original content, allowing players on the FC and NES to experience tension close to the arcade. The Japanese home version sets the story in 2633 on the Galuga Islands, where Bill and Lance fight against the Red Falcon organization and alien threats. This setting continues the arcade's sci-fi tone, placing the battlefield on a futuristic archipelago and providing a clear narrative backdrop.
The North American manual rewrote the timeline: in 1957, an object crashes near Mayan ruins in the Amazon basin; thirty years later, in 1987, the mission begins. Bill and Lance use the codenames Mad Dog and Scorpion in the US version, a change that grounds the story in a more contemporary reality, contrasting with the Japanese future setting. The European NES version was released as "Probotector," replacing human heroes and most human enemies with robots, with the protagonists' codenames being RD008 and RC011. This change gives the game a more sci-fi mechanical look, but the level structure, weapon system, and two-player cooperative mechanics remain identical to the original.
Japanese materials define "Contra" as a title bestowed upon guerrilla fighters with strong fighting spirit and innate combat abilities, a military rank within the game's world, not a description of the genre. This meaning carries the character identity and combat temperament in the title, with no direct correspondence to the actual gameplay. The arcade original was released in 1987 with a vertical screen; the FC and NES versions were redesigned for horizontal televisions, expanding the map size and adding original content. The home version was not a simple port but reorganized level layouts and enemy configurations to suit the home console's controls and display environment while retaining the arcade's tension.

The North American manual rewrote the timeline: an object crashes near Mayan ruins in the Amazon in 1957, and the mission begins thirty years later in 1987, giving the two protagonists the codenames "Mad Dog" and "Scorpion." The story backgrounds differ significantly between versions, but the gameplay flow remains unchanged. The European NES version was released as "Probotector," replacing human heroes and many human enemies with robots, with the protagonists' codenames being RD008 and RC011. Sources confirm the changes in name and content but do not explain the reason for the rename. The European cover was illustrated by Bob Wakelin, and its foreground figures were later reused, but the two actors did not officially endorse the game.
The game's visual style—alien fortresses, muscular commandos, and a mix of military and sci-fi elements—clearly echoes the imagery of 1980s action films, though it is not an official adaptation of "Predator," "First Blood," or "Aliens." This style aligns with the popular action movies of the time, naturally evoking the tough-guy characters on screen. Konami first released "Contra" in arcades in 1987, then released the Japanese FC version on February 9, 1988, with the North American NES version later that year. The home console version was not a simple port but was redesigned for horizontal television displays, expanding the map size and adding original content, allowing players on the FC and NES to experience tension close to the arcade.
The Japanese FC version sets the story in 2633 on the Galuga Islands, where Bill and Lance fight the Red Falcon organization and alien threats. The North American manual rewrote the timeline: an object crashes near Mayan ruins in the Amazon basin in 1957, and the mission begins thirty years later in 1987, with the two protagonists' codenames changed to Mad Dog and Scorpion. The story backgrounds differ significantly between versions, but both serve the same action gameplay, just with different narrative packaging. Konami stated that the home console version, while retaining the arcade's excitement, added larger level maps and more varied enemy attack patterns, rather than simply shrinking the arcade screen. This adaptation alternates between horizontal, vertical, and depth-oriented levels, combined with the one-hit-death rule, creating an experience that is both connected to and distinct from the arcade version.
Development
The Japanese FC cartridge used Konami's proprietary VRC2 memory mapper, along with a larger ROM capacity, allowing the inclusion of an opening cutscene, a progress map, level briefings, an additional music track, and several animated environmental details. These elements were not present in the arcade version and were created specifically for the home console version to enrich the gameplay experience. The North American NES version, due to cost and manufacturing considerations, used Nintendo's UNROM board, with a ROM capacity about half that of the Japanese version. As a result, map scenes, briefing screens, and several animated effects were removed or simplified, making the overall presentation more direct and closer to the arcade's compact pacing.
The hardware differences did not make the North American version a different set of levels: the core eight-level structure and gameplay remain closely aligned with the Japanese version, with differences mainly in presentation and some behavioral details. Both versions maintain the same framework, but the Japanese version feels more complete due to its capacity advantage, while the US version relies more on action itself to convey the experience. The North American NES cover's foreground figures were not newly drawn but were directly borrowed from the artwork British illustrator Bob Wakelin created for Ocean Software's European home computer version of "Gryzor." This artwork was originally for another game but was used by Konami for the US "Contra" packaging, becoming many players' first impression of the game.
Wakelin later recalled that the two characters he drew while at Ocean were combined by the company with an alien background taken from existing "Contra" assets, and the resulting composite was then used for other versions' covers. This kind of cross-work collage was not uncommon at the time, but it unexpectedly made his artwork part of the "Contra" series' visual identity. Some players, through image comparison, found that the poses of the two characters on the cover were taken from promotional photos of Arnold Schwarzenegger in "Predator." The second character's dark hair and red headband evoke Sylvester Stallone in "First Blood," but the verifiable image sources are not official endorsements from the two actors, but rather a visual borrowing.
The Japanese FC cartridge used Konami's VRC2 memory mapper and a larger ROM capacity, allowing the inclusion of an opening prologue, a progress map, level briefings, additional music cues, and dynamic environmental details. These elements provided a more complete narrative connection and visual feedback between levels in the Japanese version. The US NES cartridge, due to cost and manufacturing reasons, used Nintendo's UNROM board, with a ROM capacity about half that of the Japanese version, resulting in the removal or simplification of map scenes, briefings, and several animated effects, making the US version more direct in presentation, lacking the atmospheric buildup between levels found in the Japanese version. The US NES cover borrowed the foreground artwork from British illustrator Bob Wakelin, originally created for Ocean Software's European home computer version of "Gryzor." Wakelin later recalled that he combined the two "Gryzor" characters he drew at Ocean with an alien-style background taken from existing "Contra" assets, and this composite was then used for other "Contra" versions. Therefore, the foreground figures on the US cover were not specifically drawn for the NES version but were ready-made assets imported from the European market, with no direct correspondence to the actual in-game graphics.
The US NES cartridge, due to its use of the UNROM board, had a ROM capacity about half that of the Japanese version, leading to the removal or simplification of map scenes, level briefings, and several animated effects. This hardware limitation made the US version more streamlined in content presentation, with reduced transitional information between levels, so players relied more on in-game immediate feedback to understand progress. Although the core level structure and gameplay remained consistent, the narrative and dynamic details provided by the extra ROM space in the Japanese version were presented in a more austere manner in the US version, affecting players' perception of the game world's completeness to some extent. The Japanese FC cartridge used Konami's proprietary VRC2 memory mapper and a larger ROM capacity, allowing the inclusion of an opening cutscene, a progress map, level briefings, additional music cues, and dynamic environmental details. These elements were interspersed before the game and between levels, providing players with a richer narrative atmosphere and visual depth.
The US NES cartridge, due to cost and manufacturing reasons, used Nintendo's UNROM board, with a ROM capacity about half that of the Japanese version, so map scenes, briefings, and some animated effects were removed or simplified. Despite the reduced presentation, the core eight-level structure and gameplay remained closely related to the Japanese version, with differences mainly in the presentation layer and some behavioral details. These hardware differences did not make the US version a different set of levels but reflected the trade-offs in technical choices across different markets. The Japanese version achieved a more complete audiovisual presentation through a larger ROM, while the US version adapted to cost constraints through simplification. This technical choice shaped the differences in narrative and atmosphere between the two versions, but the core gameplay experience remained consistent.
Reception and legacy
The origin of the Konami Code is unrelated to "Contra." It was created by programmer Kazuhisa Hashimoto during the development of the FC version of "Gradius" as a simple cheat input for testing, because he found it difficult to clear the game himself. The sequence was later widely copied, but it was not originally designed for "Contra." Although "Contra" did not invent the Konami Code, it made it widely known. Entering the sequence on the title screen changed the starting lives from three to thirty, a dramatic effect that left a strong impression on players, linking the code closely with "Contra" and gradually integrating it into broader popular culture.
Contemporary reviews were generally positive. "Computer Gaming World" called the NES version an outstanding action game and praised its scrolling graphics; a later "Nintendo Power" retrospective listed it among the platform's strongest games, specifically mentioning the two-player cooperative gameplay. Retrospective reviews repeatedly highlight its responsive controls, brisk pacing, varied perspectives, and simultaneous two-player cooperation, while also acknowledging that the one-hit-death rule and limited starting lives are quite harsh for newcomers. This design makes the game feel fluid and exciting in the hands of skilled players, but beginners often need repeated attempts to adapt to its high difficulty.
Konami subsequently released multiple arcade and home console sequels, including "Super Contra," "Contra III: The Alien Wars," and "Contra: Hard Corps," turning "Contra" into an ongoing series rather than a single title. These sequels built on the core gameplay while introducing new mechanics, solidifying the series' position in the action genre. The 2019 "Contra Anniversary Collection" includes the Japanese FC version and the North American NES version, as well as the arcade original and subsequent works, along with an extra book introducing the series' history. The collection provides players with an official means to experience the differences between versions and understand the series' development.
In contemporary descriptions, Konami refers to the original "Contra" as one of the games that defined the run-and-gun genre. This assessment is more about viewing it as a lasting reference point for fast-paced shooting and local co-op, rather than proving that every subsequent run-and-gun game directly imitated it. The Konami Code was not pioneered by "Contra." Kazuhisa Hashimoto, during the development of the FC version of "Gradius," designed this input sequence as an internal aid because he found it difficult to clear the game during testing. Using the code on the title screen of this game increases the starting lives from three to thirty, a dramatic effect that closely linked the code with "Contra" and helped it enter broader popular culture.
