Grand Theft Auto: San Andreas/Blood Bowl

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.

Of all the things reqired for 100% completion, this may be the most frustrating one for the sole reason it pretty much boils down to luck whether one succeed or not and is hardly skill-related. The AI competition is mixed, one portion consists of cars that will harass you by crashing into you and firing upon you. The other smaller portion will go for the same checkpoints that the player need (the "aggressor cars" will not claim a checkpoint even if they drive through one). The AI cars are randomly assigned as they spawn, new ones will spawn as old ones are destroyed.

A further obstacle is the poor acceleration and handling of the player car that will frequently spin out of control when hit by the nimble and fast AI cars. Finally, one can't exit the car and say handicap the other cars that go for the checkpoints by shooting their tires, nor exit the vehicle after it has sustained a lot of damage and is about to explode...

Tips
You can go about destroying the cars (which is pointless unless done for fun after beating the derby once due to the respawning AI cars), but remember the goal is to collect time. Avoid the other cars and aim for the checkpoints.
