Despawn Zone at Trucking

1. Setup (Trucking)
   • You should have a high-priority call from Zero or Jethro (15s delay)
   • Phonecall start Trucking and attach a Satchel to the Truck, which cancels the call setting $OM=0, drive to the mission, get and hold a call and then explode the Satchel to fail Trucking and get $OM=0 call
   • Using a Satchel means you have no traffic on the way to the mission, because starting Trucking without ever getting into the truck prevents traffic from spawning. You should still have Satchels from Badlands. If you don't have a Satchel you can also hold the call and blow up the Truck, but then you'll have traffic.
   • There is a despawn zone around Trucking, so park your vehicle on the bridge to keep it
2. Duping
   • Having the $OM=0 call held, walk into the marker, then let go of the call once the cutscene comes up.
   • Because the cutscene is in an interior, duping in the cutscene (not cancelling the cutscene after starting the first instance, then letting go of the held call while still standing in the marker to start the second instance) will cancel the call instead of answering it, so you don't need to press F (or whatever puts down the call) for duping and you can also use the call again.
   • Once you started the second instance you can skip the cutscene.
3. Mission
   • Duping in the cutscene means you get no traffic on the roads until you enter the car
   • There will be two mission cars spawned in the parking garage, which may cause the car you get into to roll and land on your roof. To prevent getting stuck on your roof, hold "move left" (default A) and skip the cutscene after you get into the car as fast as possible. That way you can just roll around once and land on your wheels again.
4. Result
   • Skips Lure

T-Bone Mendez

1. Setup (Blood Bowl)
   • You should have a high-priority call from Zero or Jethro (15s delay)
   • There are two possible routes for this setup:
     1. Setup at Blood Bowl directly after Photo Opportunity, which requires you to carry the call through Jizzy (Cutscene) and Jizzy
        • After Blood Bowl, go to Jizzy (Cutscene)
          • Enter the marker on the side of the building, so CJ will walk out of it during the fade (what we usually want to avoid for duping, however this mission isn't going to be duped), then let got of the held $OM=0 call once the cutscene comes up, wait at least 15s so the call can come in again. Then start holding the call, skip the cutscene and the phone should ring once CJ is placed outside, just moments before the mission will pass and set $OM=0 again.
          • Simply holding the call through the Jizzy (Cutscene) will not work, because CJ will answer the call once you skip the cutscene.
        • Hold the $OM=0 call until Jizzy
          • Start the mission and skip the cutscene while still holding the call. The call will be cancelled automatically, you can let go of holding it once the cutscene showing the Pimpmobile comes up.
          • At the end of Jizzy, drive ahead of the Limo as you normally would, get out preparing to attack the Limo, start holding the call, getting out of the Pimpmobile will cause the phone to ring (make sure you don't have a wanted level), then kill the enemies. You can't use a Rocket Launcher to destroy the Limo, since aiming with the Rocket Launcher while holding a call will cause CJ to answer the call. You can either use your SMG (that the mission gives you) to shoot the driver of the Limo and then kill the other enemies or place down Satchels. Either way requires a bit of practice and traffic can troll you quite a bit.
     2. Setup at Blood Bowl after finishing Jizzy, which is a bit longer drive, but you can simply drive to T-Bone Mendez directly after the Setup
2. Duping
   • Having the $OM=0 call held, walk into the marker, then let go of the call once the cutscene comes up. Entering the marker away from the door may be safer, because CJ may walk towards the door a bit, possibly walking out of the marker.
   • Because the cutscene is in an interior, duping in the cutscene (not cancelling the cutscene after starting the first instance, then letting go of the held call while still standing in the marker to start the second instance) will cancel the call instead of answering it, so you don't need to press F (or whatever puts down the call) for duping and you can also use the call again.
   • Once you started the second instance you can skip the cutscene.
3. Mission
   • Duping in the cutscene means you get no traffic on the roads for the mission and you get interior lighting.
4. Result
   • Skips Mike Toreno

Amphibious Assault

1. Setup (Blood Bowl)
   • You should have a high-priority call from Zero, Jethro or Woozie (15s delay)
2. Duping
   • Having the $OM=0 call held, walk into the marker, then let go of the call once the cutscene comes up.
   • Because the cutscene is in an interior, duping in the cutscene (not cancelling the cutscene after starting the first instance, then letting go of the held call while still standing in the marker to start the second instance) will cancel the call instead of answering it, so you don't need to press F (or whatever puts down the call) for duping and you can also use the call again.
   • Once you started the second instance you can skip the cutscene.
3. Mission
   • Duping in the cutscene means you get no traffic on the roads and interior lighting.
   • Twice the number of patrol boats will spawn, on top of eachother. Sometimes they blow eachother up and activate the enemies, the same as if you got into the open water (which triggers the cutscene and activates the enemies).
   • Sometimes the enemies on the patrol boats can get quite dangerous, even using the Dhingy. Make sure the Dhingy doesn't end up too close to the Patrol boat when it's drifting to the front of the ship.
   • On the ship, some more enemies than usual can spawn, some apparently inside of eachother. To be able to plant the bug and advance the mission, you have to kill all enemies that are running around on the ship.
   • After the Setup with Blood Bowl you won't have an Uzi anymore, so you can either sprint and stop to shoot the enemies with a Shotgun or slide with the AK.
4. Result
   • Skips The Da Nang Thang (which aside from saved time also means you can keep your weapons)

Highjack

1. Setup (Bike School)
   • You should have a Catalina call (60s delay), so make sure the call is ready when you get to Bike School. Since it has a 1000ms check delay, pause buffering is advised to get the call consistently during the 500ms fade until the mission sets $OM=1.
   • Get a bike: Answer the call to unlock Highjack, then start Highjack, kill Cesar to fail the mission and use the spawned bike.
   • Drive to Bike School and do the setup. The call will be ready 60s after you failed Highjack, so make sure you don't fall off the bike when the call is ready, so you don't have to wait once you get to Bike School.
2. Duping
   • Having the $OM=0 call held, walk into the marker, then let go of the call once the cutscene comes up.
   • Since the cutscene is outside, CJ will take the call, so you have to also spam F (or whatever puts down the phone again) for a bit.
   • Once you started the second instance you can skip the cutscene.
3. Mission
   • Duping this mission in the cutscene will remove all traffic for the mission.
4. Result
   • Skips Interdiction.
     • You can get Rockets and AK which you would normally pick up during Interdiction from the Helipad after Toreno's Last Flight. If you also duped Amphibious Assault and skipped The Da Nang Thang, you can pick them up directly after passing Toreno's Last Flight or otherwise during Yay-Ka-Boom-Boom.
   • You'll still get the phonecall that unlocks Interdiction, which is actually used to dupe Verdant Meadows.

Verdant Meadows

1. Setup (Blood Bowl)
   • You should have the call that would normally unlock Interdiction (since you skipped Interdiction by duping Highjack you don't need it for that).
   • Go to Blood Bowl after Highjack and do the setup, then drive to Verdant Meadows.
   • Since you skipped Interdiction, the Verdant Meadows mission marker will be invisible, but it will still work.
2. Duping
   • Since this mission only consists of a cutscene, you have to dupe it in the cutscene.
   • Since the cutscene is outside, CJ will take the call, so you have to also spam F (or whatever puts down the phone again) for a bit. The dupe will occur once CJ put down the phone, so it will take a few seconds.
3. Result
   • Skips N.O.E.
   • Sets $TORENO_TOTAL_PASSED_MISSIONS to 5, like after Flight School. However, there is a separate variable that tracks if you passed Flight School, which is required to start the following missions. Luckily Flight School starts if $TORENO_TOTAL_PASSED_MISSIONS > 3 not $TORENO_TOTAL_PASSED_MISSIONS == 4, otherwise duping Verdant Meadows would basicially softlock the game. Flight School itself increases the mission chain variable as well, setting $TORENO_TOTAL_PASSED_MISSIONS to 6, so you skip the next mission instead (N.O.E.).

Fish in a Barrel

1. Setup (Bike School or Quarry)
   • You should have a Catalina call (60s delay), so make sure the call is ready when you get to Quarry/Bike School. Since it has a 1000ms check delay, pause buffering is advised to get the call consistently during the 500ms fade until the mission sets $OM=1.
   • Bike School requires a bike to drive into the building and get off into the marker. Since you're probably going to use a bike on the way to the Casino, having SMG ammo makes you shoot all the time.
   • Using Quarry you can hold the call, then blow up the truck to get $OM=0 call and drive back (having SMG ammo when holding the call on a bike makes you shoot all the time) or use a Satchel to blow the truck up remotely from the Casino, to get an $OM=0 call there (you may get shot up by the guards in the casino a bit). Since the Casino is an interior, you have to hold the call before entering the casino either way.
2. Duping
   • Since this mission only consists of a cutscene, you have to dupe it in the cutscene.
   • Having the $OM=0 call held, walk into the marker from the stairs, without sprinting, then let go of the call once the cutscene comes up.
   • CJ walks a bit towards the door, so make sure you enter the marker from the stairs, so CJ is still in the marker when you set $OM=0 after starting the first instance. CJ will sprint on the stairs if you sprinted on the previous stairs, you can switch to a weapon you can't sprint with to prevent that or don't actively press sprint on the previous stairs. Wait for the marker to appear before entering it in case you blow up the Satchel shortly before it, to make sure you actually hit the edge away from the door.
   • Once you started the second instance you can skip the cutscene.
3. Result
   • Skips Freefall.
   • You'll still get the Freefall phonecall, which will add the mission marker when answered, but it has no effect.

Black Project

1. Setup (Quarry)
   • Phonecall start Quarry and skip or answer the phonecall afterwards. As opposed to other dupes, we don't want an $OM=0 call, but instead Quarry running with $OM=0.
   • You can sprint to the Cropduster north of the Quarry while answering phonecalls if you have any left.
2. Duping
   • Start Black Project with Quarry running, which turns the Quarry instance into another Black Project instance.
   • Skip the cutscene with the Mothership as soon as it is possible, otherwise the mission can softlock (no triggers inside the facility).
3. Mission
   • There appear to be double the Armor pickups and more blips on the map, however the enemies seem to be at least similiar.
4. Result
   • Skips Green Goo.

Under some circumstances starting Black Project with Quarry can apparently crash the game (frozen at "Black Project" text). However it is currently unclear if that can actually be a problem in real runs or just some testing circumstances like doing the dupe several times without restarting the game. This requires more testing under actual run (or near actual run) conditions.
