* BEWARE HUGE STORY SPOILERS *

*These tasks will be the start of your journey. I warn you again, spoilers.*

Money rewarding side tasks[/b]

Little Jacob's and Badman's drug delivery

[2%]
Now, these mission are readily available to do at anytime after completing concrete jungle. You will recieve a text from Little Jacob, and after reading that text you can do drug running missions for Jacob by going into your phone, entering your phonebook and entering Jacobs' options. Select the 'Job' option. You will then have to go and get into a car that will be marked on your minimap. Deliever the vehicle to the target destination in the unspecified time limit. You will recieve payments upon completion of each of the 10 deliveries.

Brucie's car exports[/b][/h1] [2%]
These missions will be available after the completion of the 'Logging on' mission;recieved from Roman. After completion of this, you will recieve, at some point, a call from Roman saying that Brucie has a business proposition for us. You will thereafter be able to check your emails and you will recieve a email from Brucie with a picture of a car attached. Reply positively to this email, and you will begin a mission where you have to steal, and then deliever a car to Brucie's lockup. You will be paid a sum of money. This sum of money will be considerably less if you trash the car too bad. If you do trash the car, take it to the pay n' spray near the park in Hove Beach. There are 10 of these missions.

Brucie's races[/b][/h1] [2%]
These side missions are available after completing Brucie's mission 'No.1'. You can access these missions the same way you can access Little Jacob's;by recieving a phonecall/text, and then after the option will reside in their phone menus'. Brucies' coption is called 'Race'. These are only available at certain times, so try regularly. You are only required to do 9[/b] races. After this you will be able to do a additional 11 races, but they won't count towards your 100% mark. You will also be paid for winning each race.

Assassinations

[/b] [2%]
These missions are one of the better requirements for 100% completion. I mean, come on, who doesn't love killing people for money?Anyhow, these missions will be available after meeting Phil Bell and completing the first mission he gives you. A man called the Fixer becomes interested in using you. The phonebox near Phil's workplace will have a crosshairs on it on the worldmap. When activating these, you will be given one of the 9 jobs. You will always be left a weapon suitable to the job and body armour on the otherside of the fence that the phonebox is against.
Here are the 9 missions:

Water hazard[/b]
The target is on a boat anchored just off shore. You may want to use an RPG to send her down with the ship, or shoot them with a Sniper Rifle. After you kill the target, you will not need to worry about the police once Niko calls The Fixer telling him that he killed the target, because your wanted level will disappear once the call is made.

Dead end[/b]
The target are some members of The Lost Brotherhood, or Northwood Dominican Drug Dealers. They are in Alderney, when you come close to them they will drive away and you will have to give chase, however they will lure you into an ambush where you will have to take out many enemies.
If you take a cab to the destination, watch them drive away and then run towards their destination - you will get there after the ambush has arrived and you can easily take them out using your assault rifle. If you have a Rocket Launcher you can shoot the Patriot as it drives away to end the mission and never face the ambushers

There's an easy and fun way to take them all out easily: Keep behind the "escaping" Patriot and when the ambush is triggered, quickly get back to the street you came from, hide behind a corner and get out of the car. Now all thugs in the alleyway will run out from behind the corner one by one and you can shoot them all easily or throw a grenade for killing multiple targets at once.

Migration control[/b]
The target is attempting to catch a helicopter. Either use an RPG and blow it up when they board it, or shoot them with a sniper rifle.

Derelict target[/b]
The targets are members of the Triads, and Russian Mafia. There are 3 heavily guarded targets to be wiped out in a stripped out building in Alderney City. This is a hard mission because the police get involved regardless of whether or not you shoot anybody - it's scripted so when you get to the level where the second person is, the cops will come starting at a 1 star level and going up to two stars once you shoot another baddie. Of course, you have to move fast or end up killing policemen and your wanted level goes up to 4 stars. The easiest way to do this is to get a helicopter, go to the street level where you can see two of the targets, snipe them, and then fly to the roof of the same building and through the partially destroyed roof shoot the third person. If you do attract police, just fly away.

Bailing out for good[/b]
This target is bailing out of a police station. Kill him outside it or chase him down when he gets in his car and kill him that way. This is a realatively easy mission. There are a lot of cops in the area so you should kill him quick and then get out of the area. Also, if you run into and kill him, the mission is passed as well.

Hook, line and sinker[/b]
The target is on a boat, use a boat to get closer and give chase, shooting the boat until it explodes
A much easier way is to use a boat to get only a little closer and snipe the target. This is easiest when positioned behind the target's boat as the target's head can be covered by windshield from other directions.
You could also snipe the driver from the beach, if you're a trustworthy shot.
Note: You don't have to kill both occupants, just the driver (left seat).

R.U.B. Down[/b]
The target is in the Acter Industrial park not far to the south. However there are actually three, and they are all on bikes. Chase them down and kill them. Easier way to kill them instantly is to use a grenade. Sneak behind the concrete fence on the west side of the alleyway and throw a grenade over it. If you find yourself unable to hit them by manual aim, you can park a car by the fence and jump on its roof, then use auto-aim.

Industrial action[/b]
Three targets have to be taken out at the industrial park. They are up high on some walkways, and are guarded by a number of guards. The best way is to use a sniper form the north side and pick off as many as you can. Then get closer and take out the rest. Some targets may try to use two Landstalkers parked on the road just south of the walkway to escape.
Note: There is a $10,000 bonus on this contract. In the middle walkway between the two towers there is a sports bag that contains the money (presumably for the deal). To get the cash simply walk up to the bag. Be warned, this disappears after killing an undetermined amount of enemies.

Taken out[/b]
The target is moving in a convoy. Take a good handling car and drive up towards the target. The convoy is a stretch and two SUVs. If you are in a helicopter, slowly and methodically crash into the limousine, which pretty much makes it undriveable, and then just drill everybody with your SMG or Carbine Rifle. Another way to stop them is to get ahead of the limousine and through a Grenade outside of the window, this will stop the convoy and if you time it just right you will even be able to blow up the convoy and the target as well.

Vigilante and police missions[/h1][/b] [5%]
These missions do NOTgive you money. All you have to do is aquire a police vehicle, access the police computer and kill all of the most wanted. There are 30 in total, 10 on each island. You also have to deal with 20 'current' crimes.
