Ikari Warriors (Nintendo NES, 1987)

The country of Ikari has seen better days. Enslaved by a foreign power, Ikari needs help if it is to ever see freedom again. It's up to a couple of American soldiers, Paul and Vince, to liberate them. 

In Ikari Warriors, you and a friend take control of Paul and Vince on their quest to free Ikari. Moving vertically through the various landscapes of Ikari, it is your job to shoot your guns and throw your grenades at any enemy soldiers that get in your way. But be careful. Your firepower is limited. However, there are many power-ups that you can collect along the way to make your quest less challenging. You can even blast away enemies with a tank and a helicopter at some points in the game.
