As of my knowledge cutoff in September 2021, there are several Contra games released across various platforms. The exact number of Contra games can vary depending on how you count them, as there are mainline entries, spin-offs, and variations of the series. The Contra franchise includes classic titles like Contra, Super Contra, Contra III: The Alien Wars, as well as newer entries like Contra 4, Contra: Rogue Corps, and Contra: Shattered Soldier. In total, there are around 20 official Contra games released across consoles, handhelds, and arcades.
