Contra

In Contra, the player controls one of two armed military commandos named Bill "Mad Dog" Rizer and Lance "Scorpion" Bean, who are sent on a mission to neutralize a terrorist group called the Red Falcon Organization that is planning to take over the Earth. Details of the game's setting varies between supplementary materials: the Japanese versions sets the game in the year 2633 on the fictional "Galuga archipelago" near New Zealand, whereas the manual for the American NES version sets the game during the present in an unnamed South American island. The American storyline also changes the identity of "Red Falcon" from being the name of a terrorist organization to the name of an alien entity.
