Checkpoint Charlie mission:
To have an easier time controlling the Squallo, enable the "Slow motion" code. The speed will be decreased, but the handling of the Squallo remains the same. Since the speed is less, the handling would seem better, allowing you to complete the mission without problems. Also, after complete it for the first time, every consecutive time after that, fog will appear that gets worse with each attempt. Enable the "Normal weather" code to make it disappear.
Bombs Away mission:
Instead of chasing boats and a car, you can run over all the Cubans with the RC plane. Then. just drop the bombs and blow up the boats.
Cop Land mission:
Once accepting the mission, take Lance with you to the police station helipad in Downtown. There are stairs which lead to the helipad from ground level. Take the VCPD helicopter (Lance will get in with you), and fly it to the garage where you are supposed to trap the police officers to obtain your uniforms. Land as carefully as possible in the grassy open area just east of the garage. You will see the police car intended for you parked behind the wall in the same area. Trap two police officers to obtain their uniforms. Once you are donned in police gear, you can take any police vehicle to the mall, including the VCPD helicopter. Fly with Lance to the mall and land in the open area between the two south entrances. Once you detonate the bomb and exit the mall with Lance, enter the helicopter as soon as possible and fly over all the pursuit vehicles to the mansion. Land and run down with Lance in tow to the pink area to complete the mission. Note: Police will appear inside the mansion and on the roof; kill them off quickly to get to the checkpoint.
Death Row mission:
Go to the Malibu Club in a really fast car, such as an Inferno. Get the mission brief. Drive as fast as you can towards the junkyard. When around the corner from enable the "Rhino" code to spawn a tank. Drive towards the guards, blasting them with the tank's cannon. Once inside the junkyard, kill as many men as you can by running them over with the tank. Grab Lance and make your way back toward the tank. Then, take him to the hospital to complete the mission.
Four Iron mission:
When you arrive at the driving range, go to the line of parked Caddys. Drive your Caddy straight to the edge of the river bank, behind them next to the telephone pole. Put the front wheels hanging over the edge. Next, one at a time, use the parked Caddys to ram them off the bank and into the river. The last one you use (the pink one) should be parked with the front wheels off the bank far enough where you cannot back it off. Be careful, or you will drive off the bank and die. Your last act should be to steal the last Caddy that has the guard in it. After you hijack the Caddy, the target will send his guards after you and attempt to run. He will get into the last available Caddy (the one parked at the edge of the bank). He will eventually fall off the bank, into the river, and drown. Your mission will be complete. Do not engage the guards -- as soon as the target gets into the Caddy, drive around. You can also ram his Caddy from behind to speed things up.
Guardian Angels mission:
Get some armor, a shotgun, and at least 50 rounds of ammunition for it. When the enemies appear, jump down from the roof with your shotgun. When you get down, start aiming and shooting. When the car blocks you, jump on the hood, aim, and shoot. When you get done with the first two cars, watch the lower left corner of the map. As the yellow dots approach, get ready to aim and take fire. When you get to the dirtbike part, have a gun since you can shoot ahead and not have to use the drive-by view. Get about five to ten feet away and start shooting. When he falls off his bike, you should also get off. After this, it should be easy to finish him off and to get the money back to Diaz. Note: This may not always work. To make things easier, jump off the roof just before the enemies get there.
Keep Your Friends Close mission:
It is a very good idea to have an ample supply of either Python or Spaz Shotgun ammunition for this mission. You will start out in your office. Run out of your office and stand at the top of the staircase. Use auto-aim to target and kill the seemingly endless amounts of gangsters that enter the building. After dispatching quite a few of these Mafia members, Lance will appear near the entrance to the roof. Run after him. He will appear in the hallway as you turn -- shoot him. When you reach the roof, run up to the helipad area. Shoot down the numerous gangsters. If you lose health, locate the health behind the helicopter. There is also an adrenaline pill on the roof. The best strategy to kill Lance and his friends is to use a gun such as the Python or MP5 (something you can sprint with while holding), fire, then run away. After killing Lance, run back downstairs and prepare for Sonny. He will have a few stronger gangsters with him. Get off a few shots, then run to the side of the upstairs with the windows. Since they cannot shoot through the floor (they should be directly underneath you) shoot who you can, and when you feel ready, run back around to the front of your office and fire off more rounds. Repeat this strategy, using the health in the den when needed.
Publicity Tour mission:
Enable the "Dodo car" or "Better driving skills" code, as well as the "Car floats on water" code before mission starts. After you begin driving the car, go straight until just before you get to the water. Jump or fly over the rail onto the water then drive until the bomb gets defused without worrying about obstacles or other drivers.
Shakedown mission:
Get a motorcycle, preferably a PCJ 600. Make sure you have a sub-machine gun to do drive-bys with, and a Ruger or M4 is recommended. With the bike, enter the mall. Do drive-bys on all the stores that are marked on the bottom. It should not take that long as you have the bike to get around the mall quickly. For the top, get off your bike, run up there, and use your Ruger or M4 to take out those stores. You do not need to have an assault rifle, but it does make it slightly easier. If the cops are giving you trouble, just shoot them. You will not retain your wanted level after the mission is completed.
Trojan Voodoo mission:
When you are exiting after detonating the bombs, do not bother approaching the gate. Nothing can stop this gate from closing, and nothing will open it. Turn to your right when exiting. In the right hand corner, you will find a set of stairs. Use them to run up and onto a building. Kill all the enemies before detonating any bombs. You can also enable the "Slow motion", "Weapons", and "Armor" codes. Set the bomb on the top floor first, then the two on the bottom floor. Run quickly to the exit. Even shoot the Cubans if they get in your way. Once near the exit, turn right, then right again up the stairs and over the roof.
