Grand Theft Auto: San Andreas/Blood Bowl

Requirements

 * Legal entry to San Fierro (i.e., completing The Green Sabre)
 * Location: Stadium in San Fierro (located at the trophy cup on the map)

Walkthrough
This is a demolition derby with a computer-controlled team-mate riding shotgun, except they are actually packing SMGs. The object is to collect checkpoints and avoid damage to your car. You start with 0:30 on the timer and each checkpoint earns you 0:15 more. If it gets to zero, you lose. If it gets to 1:00, you win.

There are car repair powerups (glowing wrenches) on the course, too. Pick up these to reduce the damage to your car.

Tips
You can go about destroying the cars, but remember the goal is to collect time. Avoid the other cars and aim for the checkpoints.

Rewards

 * Cash: $10,000
 * Progress towards 100% completion
