Grand Theft Auto 2/Zaibatsu jobs (Area 1)

See here for Youtube videos that may help you.

Cop Car Crush!
Northern phone: Steal the cop car at Zarelli police station. Drive to the train station and ring the horn at the marked spot. After the informant gets in, drive to the Zaibatsu car crush and let it destroy the car. There would be other ways to get rid of the informant (like drowning him in the water) but only this one results in winning the mission. Be careful not to destroy the car while driving around.

Wheeler-Dealing!
Southern phone: Steal a fast car (B-Type, Z-Type or Cop Car will be fine), then take the drugs. You'll have 3 minutes to deliver the drugs from now. Follow the marker. Make sure not to kill the dealers before you deliver it. If you drive fast enough, eventually you'll reach all dealers. With a fast car you should be able to do it in 2 minutes. Note: Try not to be hunted by cops since they also tend to kill dealers with their cars.

Lick Those Loonies!
Western phone: Take the special Dementia (Looney car). Drive it to the bomb shop and rig it. Drive back and into the garage where it will explode. Hint: Get token 33 and 34 here. Take the flamethrower (if there's none, you may want to steal a Beamer and crush it). Now steal another car and drive down to the marked van. Take the armor and the van and get the other Zaibatsus (ring the horn). Make sure you have full health and armor, just in case. Drive back to the building where you let a car explode. Run over the Loonies and get out fast. If anyone survives, use the Flamethrower.

Yutes Must Die!
Eastern phone: Follow the Marker to Lefty. Don't kill him! Punch him instead. Now drive to the south east of the map and take the shark (if you need a flamethrower, there's one nearby to the east). Follow the marker and ring the horn. Make sure the car doesn't get damaged. If it does, you can respray it. There's no time limit. After you got the guy, you may want to get token 5 and 6. Now go into the Zaibatsu HQ and follow the marker. AFter the interrogation, drive him back to the south docks and let the crane crush him. After the car is crushed, you may want to take the Molotov cocktails. Don't take the tank to the left unless you want to start kill frenzy 9.

Big Bank Job!
Third mission: Steal the marked G4 Bank Van. Drive to the marked point but don't become wanted. Ring the horn. After both helpers got in, drive to the bank. Grab the money. Now your hunted level will rise so drive back fast. You'll have to enter the Zaibatsu HQ to find the garage. Now go to the Zaibatsu who has the money. Take it and go to the police station. Hint: If you didn't do it already, you can take token 14. Give the money to the corrupt cop and get out of the station fast. Drive back to where the marker points fast. You'll have a wanted level of 4. Alternatively, use the nearby respray to get rid of the cops. When you drive into the garage, you're done.

Armored Car Clash!
First mission: Steal a fast car. Rig it with a bomb. Try to place it near the Miara so the car explodes when the Miara is near. If this fails, steal another car and repeat. When the first Miara is destroyed, repeat this for the second Miara. It's a good idea to use red traffic lights. Also, cops tend to be annoying so respray, if necessary.

Bank Van Theft!
Second mission: Go to the bank van. Step to the marked point. When the guard is in the van, steal it. Now drive it to the Zaibatsu garage. It's that simple (well, the Yakuza and cops will follow you but if you drive good, this shoould be no problem).
