Scorelli

8-Ball has tasked Mike with whacking some of Scorelli's goons, then stealing his car.

Revenge Is Sweet

Make your way South West to an alleyway where you'll find some of Scorelli's goons and one of his high ranking officers.

You'll notice a damage meter appear on the right hand side of the screen. This shows his officers' health. There are about 5 regular enemies alongside the officer, and you'll need to take them all out. A few of them have guns, some will come at you with bats, so keep sprinting away and use the strafe functionality to back off and shoot at them as they run towards you.

The officer will take a few more hits to kill than the rest of them, but if you keep moving, you should manage to take them all out without getting killed yourself.

Lose The Heat

You'll probably have a few stars wanted level after the gun fight, so lose the cops either at the Pay N' Spray or via police bribes, then make your way to the North West of Portland where you'll find Scorelli's car in a car park.

Once you get in, you'll be ambushed by a load of his goons. Escape from the car park and head towards the South East of the map. You need to get the vehicle to the Pay 'n' Spray.

Once it's been repainted, his goons should stop chasing you, so just make your way back to 8-Ball's and drop off the car.

Mission Passed!
