Mission walkthrough

The ranch

Trevor gets the truth from Cheng at the Yellow Jack Inn and learns that the O’Neil brothers have taken his deal. Drive to the O’Neil Ranch and stop at the vantage point above the farmhouse. You have a clear view of about ten men, so pick them off from there before going down.

Clearing the house

Fight through the house room by room and go down to the basement lab. Two men load a van early on, and they drive away if you take too long. They don’t need to be killed to pass.

The fire

Pick up the Jerry Can in the lab and walk a line of gasoline through the house and out of the door. Keep it continuous, because a gap or an empty can will fail the mission. Go outside, shoot the trail and run. The house goes up, and you just have to leave the area.

Trevor crouches in a dark basement room, pouring a gasoline trail across the floor.

Trevor carries a jerry can out onto the porch of the house.

What fails this mission

Besides dying or being arrested, the mission ends if any of these happen:

The gasoline was destroyed.
The gasoline trail was incomplete.
The gasoline ran out.
Trevor was not clear of the farm house.
The farm was abandoned.
Tao Cheng dies.
The translator dies.

Gold Medal requirements

Only the ten enemies visible from the first vantage point count for headshots, so take them all from there, including the two loading the van before they drive away. For 2 Birds 1 Stone, wait for two enemies to line up. Fire single, careful shots for the 80% accuracy target.
