Contra is an arcade game released in 1987 by the Konami corporation. The player controls a commando 

who battles waves of enemies including humans, machines, mutants and aliens to reach his ultimate 

goal. Much of the game's popularity came from its two-player simultaneous gameplay, which was an 

uncommon feature in video games at the time of Contra's release. While successful in the arcades, the 

game became and remained widely popular and remembered when it was ported to the Nintendo 

Entertainment System in 1988. Contra was voted #1 by gaming website IGN.com as being the 

"Toughest Game to Beat".
