All the food has run out back on Earth and the folks are getting hungry. So they send you, the young rookie pilot, in search of enough Big Macs (no pickle, large fries) to feed the whole planet. Such culinary delights, referred to in the game as food, are to be found on the huge transporters which roam the galaxy. The radar and tracking computer tell you where the food transporters are, then it's up to you to navigate a course.
Now you must roam the ship on your 'Strangeloop'-style robo bike in search of a bite for the folks back home. While you're there you may as well help yourself to the odd bits of equipment carelessly left about the place. Of course, it's not simply a case of grab it and run, the transporter's guards will do their best to bump into you and deplete your energy reserves.
Your shopping spree completed, it's time to head back to the ship and go in search of another transporter. At this point, I was beginning to get a little bored when, whammo! - I was beset by marauding alien ships in their hordes. The aliens put paid to my space exploits several times before I discovered the perfect battle plan which, to put it mildly, was a stroke of genius. I threw the ship into maximum reverse thrust, giving me more time to pick the attackers off. Once they get behind you, you're done for.
For two pounds, Earth money, Space Hunter must be one of the best quality low-priced games in the galaxy.
