Trevor needs to find the remnants of the O’Neil brothers.
- Finish with a shooting accuracy of at least 70 percent
You will be using a sniper rifle and a thermal scope so you shouldn’t have to worry too much. You do need to aim for their heads though so you must take the time to line up your shots.
- Complete within 09:00
You will need to know where the enemies are and to skip the cutscenes in this mission otherwise you will miss the limit. The first enemy is swimming in the river so look there first. The second guy is in the middle of the woods so zoom in and look for the heat signature (see above screenshot). You can distinguish them between the animals. Then a guy will start firing rockets at you.
- Kill 3 enemies with headshots
You need to shoot all 3 of the enemies in the head for this. The one in the river, the one in the woods and the one who fires the rockets. Close down on the guy and bust his head open.
Thin The Herd
- Don’t kill any animals
As long as you don’t accidentally shoot any animal during this mission, you will get this challenge.
