This mission is a bit harder than the subtle approach as it requires more finesse.
- Kill 20 enemies with a headshot
When the enemies pour into the tunnels, go for their heads. There are also plenty of guys outside as you try and meet up with Franklin.
- Complete within 16:00
The mission doesn’t take long providing you skip ahead when you can, even small conversations.
- Drop the gold onto the train within 00:30
This is probably the fly in the ointment for this mission. It can be an absolute pain to line up with the train. Follow the other crew member’s descent towards the train and after it passes under the bridge, be prepared to drop the gold. Slow up enough so the chopper is hovering above the train. It doesn’t have to be perfect so just get it straight enough until you get the prompt.
- Finish with a shooting accuracy of at least 60 percent
You should get this through the natural course of the mission.
