Go to the O’Neal brothers’ farm and vantage point
O’Neal brothers farm is Northeast of your position. There is no time limit for completing the mission, so you can walk there if you feel like it. The vantage point is Southwest of the farm.Destroy the O’Neals meth lab

Keep in mind that the two tasks can collide here. Tasks “Accuracy” and “Headshots” can be tricky to complete, during the first playthrough. To make it possible, plan your moves, for example:
- Shoot down as many enemies as possible with a sniper rifle at the beginning, without alarming the others. This means you have to shoot down first the targets that are not on the patrol route of the nearby enemies.
- Use Trevor’s special ability whenever suitable, don’t be shy when using that skill. His special ability slows the time down, giving you a moment or two for a successful headshot. It also allows you to take some close up shots
- Sometimes headshots are not counted for even if you are sure you have made them. Keep aiming toward their heads whenever possible
- When you enter the house, there are a couple of enemies inside. Do not rush toward them, take your time, since they tend to reveal their positions behind the covers.
