Ikari Warriors is a shooter released by SNK corporation.
After a plane crash, two solders need to fight their way through one long battlefield in a single stage. They can move around with the joystick, and can change their aim simply by twisting the joystick left or right. Unlike other shooters, they have a limited number of bullets and grenades to fight against enemy solders, tanks and turrets.
The NES version adds three additional stages.
