In Final Frontier, you take control over a spaceship, which has to save the earth against enemy invasors.
For doing that, you have a on-board-cannon and some rockets for it. If you have less rockets, you can call a supplyship which places the required supplies into the space - so you have to collect it by yourself ;D.
The graphic is average, so the planet earth looks great, the effects for the rocket are looking like displaced ;D. About the sound or the backgroundmusic - you don’t have to say something about them in FF (not really avaiable ;D).
