Grand Theft Auto: San Andreas/Missions/Dupes

Highjack

Setup
- 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.
- 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.
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.
Result
- Duping this mission in the cutscene will remove all traffic for the mission.
- Skips Interdiction.
- You'll still get the phonecall that unlocks Interdiction, which is actually used to dupe Verdant Meadows.

Setup
- You should have the call that unlocks Interdiction (since you skipped Interdiction by duping Highjack).
- 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.
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.
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.).

Setup
- 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.
- Bike School requires a bike to drive into the building and get off into the marker
- Quarry you can hold the call, then blow up the truck and drive back or use a Satchel
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.
- Once you started the second instance you can skip the cutscene.
Result
- Skips Freefall
- You'll still get the Freefall phonecall, which will add the mission marker when answered, but it has no effect
