C: The Contra Adventure is a 3D action game produced by Konami and developed by Appaloosa Interactive that was released for the PlayStation in 1998.

Ray Poward (having previously retired after the events of Contra: Legacy of War), is brought back into action to re-establish contact with Tasha and neutralize the alien invaders.

There are a total of ten levels in the game, which are shown through multiple perspectives, depending on the level: 2-D side-scrolling (referred to as "Classic Contra" in the game manual), third-person (free-roaming and linear), overhead (360 degree movement), and a special "Weightless Elevator" view, which alternates between multi-directional and 3D shooting on a single screen.

All the innovations that were introduced in Contra: Legacy of War (memory card saving, hitpoints and three-dimensional fire fights) are maintained in this game.

[6] GamePro's review of the game was more positive, stating "although flawed, C: The Contra Adventure carries on the franchise with style, picking up bonus points for the variety of its gameplay modes".
