Contra 4

Contra 4 takes place two years after "Contra III: The Alien Wars," first released on the Super Nintendo in 1992. Heroes Bill and Lance again must team up to take down an oncoming alien invasion and its leader, Black Viper. Contra 4 features the same style of 2D side-scrolling gameplay that established the series 20 years ago. Players combat alien hordes with a variety of futuristic weapons while attempting to avoid pitfalls and other hazards along the way. Contra 4's action extends to both screens on the DS, allowing for larger environments and boss encounters. And as is a hallmark of the series, Contra 4 retain two-player simultaneous gameplay.
