Solar Fox
Solar Fox is an arcade game released in 1981 by Bally/Midway. It was ported to the Atari 2600 console and was also released as a Commodore-published cartridge for the Commodore 64 computer in 1983. A comic book was released in 1983 to support the story of the game. Gameplay. The player's task is to pilot a starship through a series of squared solar cell matrixes inside a rack. While capturing the cells the player must dodge waves of fireballs that are being thrown by Sentinels. These Sentinels move continuously along the perimeter of each cell  formation. When an entire field of squares is completed (by flying through each square), the game advances to the next rack. The faster a matrix is cleared, the more points are received. There are 26 solar cell matrix shapes. Every fifth matrix is a Challenge rack. During challenge racks there are no fireballs; the goal is to clear the entire field before the time runs out. Completing each Challenge round awards a letter, to form the mystery word "Helios".
