You're a trigger-happy lawman pitted against wave after wave of mean hombres. Blow away one gang and another appears. As if 80-plus on-screen bandits wasn't enough, you have to contend with Killer Cacti and Treacherous Trees!
There is the incentive of a bonus life at 20,000 points and at each 10,000 thereafter. So, the more baddies you send to Boot Hill the better.
Graphics are excellent, particularly the bad guys. Unlike many, the sound effects don't detract from your enjoyment. Adequate instructions are wittily presented on the inlay. There are options for joystick and - a nice feature - two players.
If I have a complaint it's that the screen sometimes is too crowded, though generally layout is effective.
Comparison with others are obvious, but this is a winner with lots of addictive appeal.
