Ikari Warriors is a run & gun shoot 'em up game that was developed by SNK, published in North America and Europe by Tradewest, and released for the NES in 1986. The arcade version was later ported to the Nintendo Switch by Hamster as a part of Arcade Archives.
The player takes the role of commando-like warriors named Ralf and Clark, who must try to reach the village of Ikari. Enemy units attempting to kill the player include tanks, enemy soldiers and helicopters. A number of power-ups along the way help the player achieve victory.
Players must proceed from the bottom of the screen upwards, towards the village of Ikari. Trying to prevent them from reaching the village are enemy soldiers and other units. Along the way, players may commandeer enemy tanks and helicopters (NES version) to help fight their way through the enemy personnel. The tanks are immune to enemy bullets, but have a limited supply of fuel and will sustain damage when it runs out or the tank is caught in an explosion, taking the player with it unless he can exit the tank and get clear before it blows up. The helicopters have two different weapons, a spread gun and a cannon, and may fly over water.
Rotating the joystick changes the direction the character faced independent of the direction the character was moving, as controlled by pushing the joystick. This gives the player freedom to attack or walk in eight different directions. No shot is fired from directly in front of the player; the warrior uses the machine gun in his right hand, and throws grenades with his left. If a player character takes too long moving up screen, the computer starts using "call for fire". A red spot appears below him; this is tracking fire to speed up the game.
