Operation C, released as Contra (コントラ Kontora?) in Japan and as Probotector in the PAL region, is a 1991 run-and-gun platformer shoot-'em-up game by Konami released for the Game Boy. It is the first portable installment in the Contra series and features gameplay and graphics similar to the Nintendo Entertainment System versions of Contra and Super C.


The player takes the role of Bill Rizer, who must neutralize an enemy force that is secretly storing an alien cell in their base.

As with the previous Contra games for the NES, the exact details of the game's settings varies between supplemental materials: in the Japanese version, the enemies are identified as the army of an unnamed hostile nation in an isolated South Pacific island that is seeking to use an alien cell to produce military weapons of mass destruction; in the American versions, the enemies are working for an alien entity calling itself "Black Viper".

Likewise, the main character's identity was changed from Bill (the Player 1 character from the previous arcade and console games) to Lance (the Player 2 character from the previous installments as well). Contra 4's updated chronology further mixed up the identity of this/these commando(es), changing the identity of the main character from Bill/Lance to Mad Dog and Scorpion, which were the western localized codenames for Bill and Lance, respectively. However, it must be noted that since Contra 4ʼs additions to the main storyline don't fit well with the original established Japanese chronology, it's arguable if they're still accepted as part of the official canon (although some of its ideas have been retained, nonetheless, precisely such as the existence of Mad Dog and Scorpion as individual characters).

The game has a total of five stages, many of which share design similarities to Super C (the NES version of Super Contra). The three odd-numbered stages (1, 3, and 5) are played from a side-view perspective, while the two even-numbered ones (2 and 4) are top-view. The soundtrack consists primarily of arranged background music from the original Contra, with the exception of a few tunes (namely the Area 2 theme, the Stage Select theme, the sub-boss theme in Area 3, and the ending theme).

Operation C was the first Contra game to feature auto-fire as a default feature, resulting in the removal of the Machine Gun power-up from previous games. The Laser is also removed, leaving only the Spread Gun and Fire Gun from Super C. However, the game introduces a new Homing Gun which fires bullets that chase after enemies. The Spread Gun starts out as a three way shot but it can be upgraded to a five-way version after picking it up a second time. Unlike Super C, the Fire Gun does not have chargeable shots, while the Barrier and Rapid Fire power-ups are not featured in this installment either.

Versions and re-releases

The Japanese version, simply titled Contra, allows the player to begin the game at any of the first four stages. The American and European versions only allows the Stage Select feature to be available by inputting the Konami Code.

While the rest of the game was left unchanged for the American version, the plot of the game as featured in the instruction booklet was altered for the American localization (as detailed above). The European version, Probotector, changed the main character and some of the enemies into robots, much like the European localizations of the NES installments.

Operation C is included in the Game Boy compilation Konami GB Collection, Vol. 1 released in 1997 in Japan and in 2000 in Europe. The Japanese version is identical to the original release but with added Super Game Boy border support. Even though the version of the game included with the European compilation is titled Probotector, it retains the original human characters from the Japanese release and adds full Game Boy Color support.


Nintendo Life gave the game an 8/10 score, praising the gameplay, controls, enemies, weapons and music, while suggesting that the game borrowed from Super C a bit too much. It also criticized the game's lack of multiplayer option.



  • The "C" in Operation C and Super C was originally intended to be short for "Commando" and not "Contra". This is stated on the box and packaging materials for all the home versions of Super Contra in North America (including the DOS and Amiga versions), this was likely because name policies regarding the Iran-Contra affair, which was still going on at the time.
  • This is the first Contra game not to start its life in the arcade and be a direct-to-console game.
  • The story in Probotector, the European version of this game, implies that this is the same mission as the one seen in the first game. Though such statement is considered non-canon, as the event of Operation C took place after the first two games in the official timeline.
