Gravitar
Released in 1982 by Atari, this game did not do particularly well, mainly because many found the game too hard. The object of the game is to destroy enemy planets to make space a safer place for you to travel. While doing this you need to collect fuel units, because every time you use your thrusters and/or the tractor beam it uses up your fuel.
The cabinet is in very good condition and is in full working order. At time of writing it will set you back £450, but you will have to pick it up yourself.
