"Bill Rizer has been called back to Galuga Island in this new spine-tingling mobile adventure, and this time he’s brought a new kind of help. When we last left our heroes they had conquered the alien invasion and two years later they have been called back to duty in order to defeat the Black Viper terrorist organization. With newly designed weapons, a brand new character and an even more persistent faction, Contra 4 promises to deliver an excellent mission."
