Radio Za-Za!
Northern phone: Fill your health, armor and Uzi. Peasants will attack you so shoot them when you go out. Steal a car. Drive into the Zaibatsu territory to the radio station and go right. Take the explosives (and the Molotov cocktails if you didn't already) and go north to the end of the path. Jump down to the radio station and deliver the explosives. Run away and watch the explosion. Hint: Get token 24 after the mission.

Pizza Cake!
Southern phone: Go to the city university. Enter it from the north but don't take the stairs (if you do, you'll end at token 48). Instead, go along the path to the south and take the explosives. Go out and to the southwest, following the marker. After a failed terror attempt, steal a car (the Minx in the university will do fine) and get a rocket launcher, some molotovs, an Uzi or even a car bomb. Now drive to the pizza van and blow it up.

Who's Mad?
Western phone: Drive to Cosmo Trouble. You're attacked by three hitman so kill them. The nearby Wellard is useful.

Destroy J-Lab!
Eastern phone: Pick up the explosives from the university. Go to the J-Lab. Kill the guards (a flamethrower is very useful here). After this, set the explosives and go up the stairs to watch the explosion. After the mission, you can fill up your rocket launcher by following the way to two crates.

Dimentia To Go!
(sic) Third mission: Meet Dodo at the University. After the meeting, go to the hotel and pick up the weapons. Now drive to Lance. Pick him up and drive to the police garage. Beware, he may drive over you if you're in the way. When they're away, use nearby stairs to get inside. Kill the guard. Use Molotovs to deactivate the door locker. Take the Dementia Limousine and drive it to the marked Looney garage.

Taxi Drivers Must Die!
First mission: Steal the first taxi. Run over the driver or kill it otherwise. Take the taxi to the south docks on the south east corner of the map. Let it be crushed. Steal the second taxi. Kill both drivers and also drive it to the docks to crush it. Now go to the third taxi and steal it. This time, kill all five drivers. Afterwards crush it at the south docks.

Gang War A-Go-Go!
Second mission: Steal a Z-Type. Drive into Yakuza territory and use it to run over the three top Yakuza. When they're dead, steal a Miara and drive to Zaibatsu territory. Kill the three top Zaibatsu. Be warned: If you leave the car or a victim can flee, you have failed.
