Time to save the world from the tyranny of perfume!
Head to the eastern coast as any character and watch the cut scene.
You will be automatically switched to Michael. Drive the boat a brief way along the coast to the way point.
Now dive in the water and follow the others.
Once you arrive at the grill, use the cutter to slice through the bars. Aim the cutter toward the edge of the grill, directly on the green lines. Only use it on the green sections, as the cutter has a limited amount of fuel. You're in the right spot if the tip of the cutter gets brighter.
Now follow Steve and Dave through the cooling shaft.
Climb the ladder to the south.
Using only the Stun-gun, head into the next room and stun the scientist there.
Stun the guy in the corridor.
Taze the guy on the elevator and obtain his security pass.
Get on the elevator to the next floor.
Follow Dave and Steve and stun the two security guards.
Walk to the door to use the Security pass.
Follow Dave and Steve to the next rooms.
The Nerve Agent will be locked in a room with a scientist. He will need some convincing to open the door. Wait until another scientist comes strolling down the corridor, stun him and the other scientist will grant you access to the Nerve Agent room.
Head into the room to grab the Nerve Agent.
Now follow Dave and Steve.
Take cover to the side of the door.
Before switching to live ammo, stun one more enemy for a gold condition. Then switch to live ammo.
The next few sections are clear and apparent. Take cover as you move through the building shooting enemies on your way to the exit. This is very simple, as long as you keep covered and clear enemies before moving to the next sections.
Now take the Nerve Agent to the storage container.
You will be automatically switched to Trevor. You will need to pick up the storage container.
Get low and hover over top of the container, a cut scene finishes the job.
After the cut scene, fly back to Sandy Shores Airfield.
Now this is a difficult part of this mission. You need to drop the storage container on the flatbed, with out destroying it. Hover towards the flatbed slow and low, use the rudders to guide the chopper in. Once you get prompted to drop the container, hit the right directional pad and a cut scene finishes the job.
Now land the chopper on the way point and watch the cut scene.
You will be automatically switched to Trevor. Listen to the heartfelt goodbye with Patricia as you drive her home.
Then watch the final cut scene and the mission ends.
To get gold:
- Stunner - Use the Stun Gun on eight enemies. Zap all 7 scientists and at least one guard with the Stungun.
- Headshots - Kill fifteen enemies with headshots. Use auto aim, push up, and then shoot.
- Accuracy - Finish with a shooting accuracy of at least 70%. Use auto aim on the enemies and you will nail this one.
- Time - Complete the mission in 13 minutes and 30 Seconds. Stay close to Dave and Steve while swimming. The helicopter sections will take up the most time, so be quick yet precise on the pickup and drop off.
