I found this to be a well-thought-out game of its type. The scenario is a rifle range with a wide variety of objects passing in front of your gun and barely sufficient ammunition with which to hit them. Extra bullets can be earned by shooting the appropriately numbered boxes as they appear.
Bonus points are earned for shooting groups of letters in sequence within a time limit in addition to normal hits. Interest in the game is furthered by the inclusion of the infamous 'Smiley' who traverses the rear shelves only to periodically descend and steal bullets if not shot.
A second screen shows a man attempting to reach the side boundaries, when shot he runs the other way until shot again, continuing until his speed defeats and you return to the fair.
Strangely addictive with good sound effects and graphics and with easy key operation this game should keep a room in silence - providing the option of removing the background music is exercised with the first bullet. Incorporating a 'hold' facility and a hall of fame this game grows on you.
