You will control in Ufo Mars a flying object round like a saucer and this is nothing but a marvel of alien technology. Your task is to go through levels where various targets and objects will appear that attack you. To get started, raise the ship off the platform by controlling the arrow keys. Take off to patrol your part of the galaxy, preventing foreign objects from penetrating into it. If you see any, shoot without warning. Having cleared the perimeter in this way, you will smoothly move to a new level and continue to defend your positions in Ufo Mars.
