In G-Fighter you move around in a full 360-degree circle and shoot inwards towards enemies that fly outwards (and inwards) to group in the center. You cannot collide with enemy ships, however you can collide with: asteroids, enemy bullets (red stars), and shockers (blue electricity).

You receive an extra life after 60,000 points. The game has a total of 30 warps, each one progressively harder.

The game starts out rather easy, but the excitement begins to ramp up quickly after a while!
