Starting Location: Crystal Maze

Location: Grand Senora Desert / Yellow Jack Inn
Quest Giver: Mr. Cheng
Requirement: Complete “Trevor Philips Industries“
Can Be Started By: Trevor

Go to the O’Neil Brothers’ Farm

Looks like Trevor’s big international deal is being scooped by the O’Neil Brothers. We’ll see about that. Head to the objective marker and park.

Get to the Vantage Point on the Hill

Get out of your truck and climb the nearby hill where you can look down upon the O’Neil Brothers’ farm. Equip your sniper rifle and remember the Gold Medal requirements:

Headshots: Kill 10 enemies with a headshot
Accuracy: Finish with a shooting accuracy of at least 80%

Destroy the O’Neils’ Meth Lab

You can kill everyone visible without breaking stealth if you do it right. First take out the guy on the second floor balcony with the binoculars.

Next look just to the right were you’ll see one brother standing still and a second who comes over to talk to him. While they are talking, they’ll shift their weight from one side to the other and eventually their heads will line up for the perfect shot.

2 Birds, 1 Stone: Kill 2 enemies with one shot

If you find they don’t line up properly, move a bit to the right on the hill and wait for the second brother to come back on his next patrol. Next, move down to the first floor and kill the O’Neil standing on the front porch, then the one in the first floor window. Be careful with this one not to accidentally hit the window’s crossbeam or he will become alerted. You’ll then have to kill him quickly before he raises the alarm.

Just to the right of that window is another chance to get 2 Birds, 1 Stone if you missed it the first time. Again, wait for their swaying to line up their heads for the shot.

Just be ready to kill the two brothers rolling barrels up the hill who will likely be alerted by the previous twofer. Take them out quickly before they raise the alarm.

Finally take out the two O’Neils doing target practice in front of the barn, starting with the back one first. Incidentally this is also a third chance to get 2 Birds, 1 Stone if you’ve somehow missed the first two. Just know that you’ll have to get off the hill and move a fair bit to the left to line them up if you have to.

That takes care of everyone outside the house. Next head to the front steps and see if you can make it to the door without being spotted.

Once inside activate Trevor’s special ability to ensure you have damage resistance, to meet the last Gold Medal requirement:

Unmarked: Complete with minimal damage to health and armor

Remember that you still have an accuracy requirement, and probably still need a few headshots to make Gold. Luckily Trevor’s invulnerability gives you a lot of leeway to call your shots, so try to make them count. The O’Neils inside will move randomly but if you’ve shot the one that was in the window, you’re looking at 9 remaining O’Neils on the main floor and one in the basement. Watch your minimap for their positions, and keep an eye out for any that go through a side rooms to try and flank you.

When your special ability runs out, take cover and wait. Get a headshot if you can to build the meter, but on this mission any kill will build it quickly so don’t endanger yourself unnecessarily. There’s no Gold Medal requirement for time, so choose your moment. Wait till it’s back up to about half then activate it again go room to room to finish off any survivors left on the main floor.

The last O’Neil is in the basement, unarmed. Unfortunately for him he’s still got a head and will boost your accuracy since he’s not moving. Oh well.

Pick Up the Jerry Can

Who stores gasoline in a meth lab?! Well, the O’Neils apparently, so grab the can by the shelf and help Trevor redecorate the farm.

Pour a Gasoline Trail Leading Outside

A yellow dotted trail will appear on your minimap showing the route that you should follow to pour the gasoline trail. Move to the start of the trail, and hold / to begin pouring gas. Don’t let go until you’ve reached the end outside.

Now be careful where you’re walking while pouring the gas. To burn down the meth lab you’ll need an uninterrupted line of gasoline that leads all the way downstairs. Any interruption will cause the flame to burn out and you’ll fail the mission. If that happens though, you can hit / to retry and you’ll start back in the basement with the jerry can to try again, and can still get the Gold Medal. Still, if you want to get it right the first time make sure you avoid clipping the corner of this table, or pouring gas over random debris on the floor like the trash bags on the porch.
