C.R.A.S.H.
Snail Trail
Another joyous assassination mission from Officer Tenpenny, who wants you to shut up a journalist and a snitch. This one’s simple, but annoyingly time-consuming, as you’ll have to follow the train that the journalist’s on all the way to Los Santos. In point of fact, you shouldn’t follow it at all, but rather speed ahead of it until you reach Market Station in Los Santos, at which point you can get out of your car and jack a new one on the street above in preparation for following the journalist after he gets a taxi. Once the journo makes it to the pier, kill both of the targets to complete the mission.
Zero
A note: Zero’s missions are optional; you don’t have to complete them to finish the game. Keep this in mind when you hit the Supply Lines mission, which can be terrifically frustrating. If you do manage to complete these missions, though, you’ll unlock the RC Shop as an asset, which will generate money for you over time.
Air Raid
Air Raid may be just another point-and-shoot mission, but it’s a toughie. Your goal is to protect Zero’s transmitters from hordes of incoming RC airplanes. You have a minigun with unlimited ammo, but your targets are very small, and the minigun jumps when it fires. If you want to up your kills, don’t fire while aiming; you’ll improve your accuracy if you’re zeroed in on a target before blowing it out of the sky. Also, keep an eye on your radar to discern between the incoming targets and those that are leaving the area; after a plane drops its bomb, it crashes, so don’t waste your time shooting anything other than incoming targets. Also, keep an eye out for clumps of planes; there are a couple of instances of planes arriving in groups of four or five. If you can’t shoot them all down, you’ll probably lose a transmitter.
Supply Lines...
Supply Lines is one of those missions that separates the men from the boys. It’s almost certainly going to be the most difficult mission you’ve come up against thus far, if not in the entire game, so don’t feel too frustrated if you don’t succeed on your first few (dozen) tries.
The basic gist of it is that Zero wants you to take a remote-controlled plane, find five of Berkeley’s deliverymen, kill them with the plane’s machineguns, and return the plane to Berkeley’s shop without the plane running out of fuel or getting shot down. The first time you get into the plane, though, just ignore the deliverymen and concentrate on learning how to fly the plane itself, as it’s a beast to control. What you should try to focus on is keeping the plane level and lining up behind targets before throttling back and opening up with your machineguns.
Video Walk-through
This is hardly a perfect run, but we still made it back with fuel to spare.
The deliverymen travel much more slowly than most cars, which is to your benefit, but you’ll still be required to make an almost perfect run if you want to get the plane back to Zero’s place while it still has fuel left. The trickiest one to take out will be the deliveryman on the motorcycle, as he’ll fire back at you after he’s alerted to your presence, and can shoot down the plane relatively quickly, so focus on getting him lined up before you open fire. If you find yourself consistently crashing and burning due to lack of fuel, try running a different route on your next attempt. The van to the south of your start point is usually a good place to start, as he will continue moving south from there and will require more fuel to hit if you save him for later.
(If you're having a lot of trouble beating this mission, and are willing to cheat to get past it, enter the Faster Gameplay code. This will let the plane move much more quickly than normal, without burning extra fuel. If you want to revert to normal afterwards, use the Slower Gameplay code to counteract the effects of the first code.)
If you have a truly difficult time hitting people, try landing the plane behind or in front of a target and firing from the ground. You can rotate on the ground by using the R2 and L2 buttons to line up with your target. Also, keep the X button depressed while you’re in the air; it doesn’t affect your fuel consumption at all. If you want more time to fire on a target while flying, hit the Square button to decelerate.
Beyond those rudimentary tips, this is essentially a mission based on a little bit of skill and a whole lot of luck.
New Model Army
Zero’s last mission involves a large-scale model of a battlefield. Zero’s going to be attempting to enter Berkeley’s base in his little car, while you get to do the heavy lifting in your helicopter. Don’t worry, though; if you passed the last mission, this one should be cake.
Video Walk-through
This mission isn't nearly as difficult as the last one, but still requires a bit of skill.
Take a couple seconds to get used to how the helicopter handles; it’s much easier to control than the model airplane. Your primary tasks here are: lifting barrels out of the way of the car; placing planks across the rivers that don’t already have bridges; and destroying Berkeley’s tanks with bombs. You can use your magnet with the O button, but you can’t hold it down; you have to tap it while you’re hovering over a metallic object in order to trigger it. The biggest risk of failure comes from the tanks, which can quickly damage Zero’s buggy if you let them. You can use bombs to kill them in one good shot, or you can drop barrels on them form a height to inflict somewhat less severe damage. Barrels are sometimes the better choice, though, especially if you’re low on time. If you find that things are going well, though, you may want to leave Zero at one of the barrel obstacles and grab bombs to take out the tanks before they get a chance to hit him.
When you complete this mission, you’ll gain the RC Shop asset, which will generate cash for you over time, as well as a cool 7,000 smackers up front.
