Ikari Warriors (Data East USA)

Ikari Warriors is a vertically scrolling action game where one or two players fight their way through a variety of terrain, such as jungles, rivers, and ruins. Along the way different weapons can be found, including machine guns, grenades, and rocket launchers. Not to be confused with the Elite version of the game put out the following year.

There are two completely different C64 conversions of the game. The US version was done by Quicksilver. The European version was done by Elite. The European version has better graphics, sound, and gameplay. It also uses the upper and lower screenborder and doesn't use the whole horizontal resolution to imitate the vertical look of the arcade.

This is the North American version.
