Contra: Hard Corps (1994)
Contra: Hard Corps is a side-scrolling run and gun-style shoot-'em-up video game. The objective of each stage of the game is to reach the end by shooting at every enemy that gets in the way, and fight the boss awaiting at the end. While most of the game have the character walking on foot, certain stages have the player riding a Motoroid, a hoverbike that can transform into an ostrich-like robot. (wikipedia.org).
