The player's task is to pilot a starship through a series of squared solar cell matrixes inside a rack. While capturing the cells you must dodge waves of fireballs that are being thrown by Sentinels. These Sentinels move continuously along the perimeter of each cell formation. When you clear an entire field of squares (by flying through each square), you go on to the next level (rack). The faster you clear a matrix, the more points you receive. 
There are 26 different solar cell matrixes shapes, every fifth matrix you reach a Challenge rack. During challenge racks there're no fireballs, but you have to clear the entire field before the time runs out.
- After completing each Challenge round you get a letter, to form the mystery word Helios.
- Maximum of 100 Racks are available.
- Score points reset to 0 after 1000000
- A comic book was released to support the story of the game.
