The Nippon version allows players a life bar that can hold 3 hits before you lost a life but also provide an infinite continues system. In addition, there are a main difference which affect the gameplay.

This probably explains the reason that we have on Contra Japanese and American versions: robots are piloted by humans and not on Probotector. But a secret department found out that an alien from the galaxy is planning to eradicate humanity.

On Probotector, we are in 2633 at an advanced technology stage that allow human and science to live peacefully. In fact, the difference is found directly from the lore, in the Contra’s Serie the story occurs in 1957 when a strange object from the outer space crashed to the Earth’s ocean. Your main objective is a bit different: all through you will be in charge to look into the X-Drive and not for the Alien Cell. Plus, you will find some facelifts and replacements on the enemy side: they are kinda mutators now and no longer names are given to them. Some sentences have been reviewed in order to remove any vulgarity. Secondly, we sure do have presence of dissimilarities within the history that provides the original Contra to have much more detailed dialogues accompanied with references about precedent Contra’s episodes that finally give the story a better pulsating plot. This also apply to some antagonists and protagonists, your opponent’s name is changed to generic names, your chief is now a robot, etc

The character’s name differs too and are labelled as robot code names ‘CX-#’ contrary to ‘human’ names in Contra. In first, we have characters which are all robots in the Probotector’s saga as the opposite of all humans in the Contra’s Serie. As said above, there are a few differences between the two versions (Contra vs Probotector).
