WALKTHROUGH VIDEO COMING SOON
This mission has three parts. As soon as you pick option C, Franklin will call Lester, who will tell him to meet him at his house. When Franklin arrives at Lester's house, and he explains the situation, Lester suggests killing Michael and then killing Trevor. However, Franklin is having none of it. Eventually, Lester comes up with a plan and tells Franklin to meet Michael and Trevor at the foundry, where they will ambush the FIB.
Part 1: Foundry Shootout
Go pick up Lamar at his house
Following the opening cutscene, Franklin will call Lamar. Go to Lamar's house and pick him up, and then drive to the foundry.
When you arrive, Lamar gets out of the car and waits outside, while Franklin goes in to meet Michael and Trevor. After a brief argument between the trio, they take their positions and prepare for the ensuing fight.
Ambush the FIB team when ready
Switch between each of the characters as necessary and eliminate the FIB team that is attacking.
When the FIB team is eliminated, several Merryweather teams will join the attack, and will also attack the FIB teams as well. Use this to your advantage.
Go to Lamar
Lamar sends out a distress signal. Switch to Franklin and get to Lamar, who is outside.
Take out the attackers
As soon as you get outside, take cover and eliminate the attackers.
After a short while, Michael sends out a distress signal that Trevor is in trouble. Switch to Michael, and fight your way to Trevor, who is pinned down by attackers.
Take out the attackers
Take cover where Trevor is, and take out the incoming FIB attackers.
Once the last of the attackers inside the foundry are eliminated, follow Trevor to the exit. More Merryweather soldiers will be waiting for them, including attack helicopters. Get to cover and eliminate them, switching between each of the characters as necessary in order to get the job done.
Regroup outside the main doors
Once the last of the FIB and Merryweather soldiers have been taken out, regroup at the main entrance outside.
Part 2: Killing the Targets
Get rid of Mr. Cheng/Escape the Triads
Drive out to Mr. Cheng's location, marked on your map, and eliminate him. The easiest way to do this is using Sticky Bombs (which is also a gold medal requirement). Escape or kill the other triads once dealt with.
Take out Stretch/Escape the Ballas
Approach Stretch and eliminate him. If gold is your aim, you'll need to exit your vehicle and have Michael down him mono e mono. Once he's dealt with, escape the pursuing Ballas.
Bring down Haines/Lose the Cops
Approach Haines' location, who is on the Ferris wheel. Use a Sniper Rifle to eliminate him from afar. When Haines has been eliminated, you'll have to lose the cops.
Part 3: Kidnap Devin
Go to Devin's house
With the last target killed, drive out to Devin Weston's house, marked on your map.
Take out the guards
Eliminate the Merryweather guards protecting him and guarding his estate, and go to Devin's location by the pool. Try to use stealth and silenced weapons to avoid alerting them.
When the guards are eliminated, approach Devin's location, and kidnap him.
Go to the rendezvous point
Drive out to the rendezvous point out at the Mount Chiliad State Wilderness, where Michael and Franklin will be waiting.
