Contra: Hard Corps is the only game of the Contra series released on the Genesis / Mega Drive console. In this game, you get to choose between four characters, each with different abilities and weapons.
This game has four completely different final stages, each with a different ending, depending on the choices you make earlier.
Browny (the robot) is used in this video because of his Yo-Yo weapon, which has huge damage but short range. For example, the first boss is killed so quickly with it, that he never enters his second attack mode.
