Operation C

Operation C (released as Contra (コントラ, Kontora)#cite_note-Jpntitle-3) in Japan and as Probotector in the PAL region) is a 1991 run and gun video game by Konami released for the Game Boy. It is a sequel to Super Contra, and the first portable installment in the Contra series "Contra (series)"). Operation C features gameplay and graphics similar to the Nintendo Entertainment System versions of Contra and Super Contra. 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).
