The Paleto Score
Send any character to the H that appears on the map after completing "Military Hardware" at Trevor's Meth Lab. Enter the store and go through the "Private: No Entry" door, then through the rear door leading to the back staircase. Go up the stairs onto the second floor of the building which triggers a cut scene: Trevor and Michael are still arguing over trivial matters. However the team still head for their move on Paleto Bay.
You now control Michael, get in the white van and drive along the yellow route to the pier. Here is where Franklin is dropped off and heads off to the getaway boat. Follow the new yellow route to the bank parking lot and park near the entrance. Aim your weapon and customers and staff to get them on the ground.
Move to the vault where your gunman kneels, cutting through the lock with a torch. This triggers a quick cutscene: Michael kicks open the vault gate and Trevor chases off after the first sheriff's department unit that arrives. Note the take amount increasing in the lower-right corner as Michael and the gunman clear out the vault. Outside, the Sheriffs men confirm the bank robbery is in progress.
After the first Cutscene you control Trevor. Direct him to the vault which triggers a second cut scene: the police response is immediate and huge, with many cars and troopers cordoning off the bank lot. Your take increases to $8,000,000. Finally you see your trio emerge from the bank dressed in military hard-suits you stole in the set up mission.
You now control Trevor as the battle begins who is wielding a powerful Minigun that can quickly tear apart vehicles and cause them to explode. Open fire on the outgunned sheriff forces. Target the cars and be sure to watch out for the Police Helicopter that joins in.
After the chopper has been taken care of, a quick cut scene begins that shows the Helicoper spinning uncontrollably to the ground in flames. It slams into the San Andreas Apartment complex across Cascabel Avenue from the bank.
Switch to Michael at the entry point to the South Seas apartments courtyard. Franklin tells Michael via radio that the boar rendezvous is off; Franklin needs to pick up the team in town. Go through the arch into the shattered garden area where the Police Helicopter crashed into the swimming pool. After a screaming woman runs past you, turn right and take on the cops on Procopio Drive.
After all three guys are gathered at the pool, you get a new objective and route. Move past the burning chopper and shoot through the wooden fence, Run through the opening into the backyard of the adjacent house and shoot through the next wooden fence. Proceed onto Paleto Boulevard where you will see a Famous Hamburgers to your left and a liq our / Deli store to the right. As you reach the street, some NOOSE units arrive in armored vans. Use Trevor to destroy the vehicles.
Soon after, a Sheriffs car with scream towards you up Pyrite avenue and skids sideways to form a roadblock. Stay behind a parked car for cover and take out the attackers. Fight your way down Pyrite until a bit military helicopter lands at the end of the street. This triggers a cut scene: The military chopper is too heavy for flight so Michael leads the team up an alley and to the right, just past Del Veccio Liquor.
When the scene ends, you control Trevor. A cop car speeds in from the right. If you picked a low skilled gunman, the car will pin him against a power box. He is either dead or trapped. Either way, he isn't getting out, so run up to him and grab his cash the follow Michael past the fence with the "Beware of the Dog" sign into the junkyard full of brute equipment.
Military units in jeeps suddenly appear and race into the junkyard. Now you need to kill the soliders than are deployed across the area. Use Trevor's minigun to target their jeeps, the explosion will take out the majority near the vehicles. Keep killing the men until a cutscene is triggered: A military chopper passes overhead carrying a tank into the battle. Switch to Franklin.
Drive down the street in the yellow bulldozer Franklin has acquired from an excavation project. Follow the blue dot on the map to the crews location in the Junkyard, ramming through the military jeeps that get in the way. When you cross Pyrite avenue, a tank rolls into the intersection from the left. Veer into the Junkyard just half a block ahead to the left. Arrival will trigger a cut scene: Michael and Trevor get into the bulldozers shovel as the tank rolls round the corner into the Junkyard.
The tank opens fire at the bulldozer. Make a beeline out of the lot, cut a hard left turn on to the Great Ocean Highway, and then follow the short yellow route to the open garage door of the Cluckin' Bell Farms chicken factory on the right. You'll need to be quick as another tank blocks the road just ahead and turns to open fire at the dozer.
After a short cutscene, you control Michael again. Head into the factory, past the chicken cages and workers. Shoot the soldiers through the divider and then keep on moving. Keep an eye on the radar for any red dots that appear as threats and continue to navigate through the factory following the yellow destination marker that marks the railway platform. Be sure to check how much health your character has, a tip here is to switch to another character if your health gets too low and move him to take the lead. You can also switch characters for better shooting angles too.
Once at the destination, fight off the waves of soldiers while you wait for transport. A tip is to activate Trevor's rage to take them all out. When the train finally arrives, lead the trio to the platform to trigger a cutscene: the three men jump into the rail cart and escape the scene of the heist.
The mission ends on a cinematic in which FIB Agent Andreas Sanchez meets the team at Sandy Shores station and collects the money to fund the next mission. He says Agent Haines will be in touch when the time is right. He then gives a small take to each member of the crew, and everyone scatters.
