The Humane Labs Raid is a four-man heist with a setup cost of $54,000, the total reward is $270,000. This heist involves a raid on Humane Labs and Research to obtain classified files from IAA Agent Karen Daniels.
Set-up 1 - Key Codes
The purpose is to obtain access codes to get into a room in the Humane Labs buildings. The four roles in this heist are: Bodyguard, Buyer, Lookout North, and Lookout South. This involves driving to the designated parking lot and each member taking up their position. As soon as the exchange has taken place the FIB arrive and you will need to kill everyone and escape.
Set-up 2 - Insurgents
You now need to steal two Insurgent SUV's from a Merryweather test site in Davis Quartz. Drive to the quarry and smash through the guards at the gate and make your way to the Vehicles splitting into two teams. Use the Insurgent with the mounted gun to deal with the two attack choppers that arrive as you make your getaway.
Set-up 3 - EMP
This involves stealing a Hydra fitted with an EMP device from an Aircraft Carrie. Use the dinghy on the beach to reach the back of the carrier and make your way to the top deck where the Hydra is located. One member of the heist pilots the Hydra while the other three are the ground crew who steal the three Lasers on the deck and deal with the pursuing jets intent on taking down the Hydra.
Set-up 4 - Valkyrie
You need to steal a heavily armed Valkyrie helicopter from the Los Santos Naval Port where it is being stored for military use. This involves killing the Merrweather guards at the entrance and make your way to the rear of the port where you will find the Valkyrie on a helipad. Once the Valkyrie has been collected you need to deal with the two Froggers and one Buzzard that then attacks you. The three helicopters that then appear afterwards in the distance can be dealt with using snipers and Homing Launchers.
Set-up 5 - Deliver EMP
This is a timed stealth mission to deliver the EMP to the research lab in an unarmed Insurgent. For this to be successful simultaneous take-downs with silenced Weapons need to be used to eliminate the enemies. The object is to place the EMP inside the lab so it can be detonated during the finale.
Finale
There are two teams, the Ground Crew and the Chopper Crew. The Ground crew enter the lab and steals the documents while the Chopper Crew flies around outside in the Valkyrie and picks up the Ground Crew members when they leave the lab. As you make your getaway you will be attacked by a squadron of Buzzards which can be dealt with using the Valkyries many Weapons before heading towards the meeting point.
