contra dual spirits
Contra: Dual Spirits (魂斗羅 デュアルスピリッツ), released in the United States as Contra 4, is a 2D shooter video game for the Nintendo DS and the eleventh original installment in the Contra series.
The game was released in North America on November 13, 2007 and in Japan on March 13, 2008. Contra 4 was produced by Konami Digital Entertainment in America and developed by WayForward Technologies, making it the first Contra game developed by a foreign western company, as well as the first original Contra game for a portable platform since the 1991 Game Boy game Operation C.
As the game's title indicates, Contra 4 was designed to be a direct sequel to the Contra games for the Nintendo Entertainment System and Super Nintendo (Contra, Super Contra, and Contra III The Alien Wars), with a gameplay model similar to those games. In celebration of the 20th anniversary of the original Contra the game also includes several playable characters from many different Contra games.
