Someone is stealing Trevor's business. Time for those aggressive business strategies Trevor is so good at.
Head to the bar where Trevor first met Cheng. Watch the cut scene.
Now drive out to the O'Neill-Brothers' farm. Watch the cut scene.
Now you can do this mission 2 ways, stealthy or guns blazing. Stealthy is easier, but guns blazing is great fun. You will have to make up your mind which way you think is best.
Now creep around the back of the house, keeping away from windows to avoid detection. There is a back door you can utilize without any hassle.
Now just move from room to room wiping out the O'Neill's. This is very easy as long as you stick to sound suppressed weapons. Use anything else and you will start a massive shootout. You're better off avoiding the shootout.
Now your destination is the basement lab. Use your mini map to help you locate it. Make sure to kill the guy here before he shoots you.
Grab the jerrycan off the floor and coat the yellow dotted trail on your map with gasoline. Once your outside, shoot the trail with any gun to get the fire started.
Now jump on the four wheeler and drive a way from this house until the mission ends.
To get Gold:
- Headshots - Get ten headshots. If you're using the Sniper Rifle, its easy.
- Unmarked - Complete the mission with minimal damage. Use stealth and this is too easy. Otherwise take cover and utilize Trevor's special ability frequently.
- 2 Birds 1 Stone - Kill two enemies with one shot. You need to use your Sniper Rifle. Look for two guys having a conversation and shoot 'em.
- Accuracy - Finish with a 80% shooting accuracy. The Sniper Rifle makes this easy. If you go in with guns blazing, make sure to use auto aim.
