The aim of this arcade game is to launch missiles from the bottom of the screen at enemy spacecraft located at the top. To get there, the missile must pass through an asteroid belt flying across the screen and avoid the shots being fired down from the spacecraft. It is the player's job to control the missile. Once launched it can be moved left and right and can be sped up by using the boost to speed it's way out of trouble. Points scored depend on the location of the hit on the enemy spacecraft. The speed at which enemy spacecraft move increases as the number of them decreases. Once all spacecraft have been destroyed, another wave starts, the speed decreases again and the process repeats. A life is lost when a missile is hit by a shot or collides with an asteroid.
On the Super Famicom , three game modes are available: B&W mode recreates the graphics and behaviour of the original arcade game in black & white, Color mode updates the game with improved graphics and slightly different behaviour. Neo mode offers improved graphics and a new experience. There's also a turn-based two player mode. Other options include changing the number of lives available at the start of a game and the number of points needed for an extra ship.
Galaxy Wars , released on 1995-01-13 , is an action-packed experience that challenges players to control their missiles through increasingly difficult asteroid fields and enemy attacks.
