GTA Online ULP: Cleanup Mission Walkthrough

Agent ULP sends you into Avon Hertz’s abandoned missile silo under Mount Chiliad to destroy the last copies of the Cliffford software. You restore the power, wipe the servers, fight off the machines that wake up, then escape to the IAA facility.

Before you start

Bring a flashlight attachment on your weapon, because the silo is pitch dark until the power is back.

Carry a rifle or machine gun and plenty of ammo for the Juggernauts, plus a rocket launcher if you have one for the helicopter outside.

Wear full armor and take snacks; the escape is long and hard to rest in.

A team helps, since one player can keep the Juggernauts busy while another stays at a server.

ULP – Cleanup walkthrough

Fly to the silo

Take the IAA helicopter that ULP has left at the construction site, or drive if you prefer. Follow the marker north to Mount Chiliad and keep the helicopter low over the desert, because the climb to the summit is steep. ULP explains what you are looking for on the way. Land near the blast doors at the top and enter through the personnel hatch.

Restore the power

The silo starts completely dark, so switch on your weapon’s flashlight and head for the control room. Check each doorway before you step through. The power breaker needs a few tries and the lever does nothing, because four fuses have blown. Search the rooms and crates around the silo for the spare fuses and take each one you find.

Replace the fuses

Once you hold all four fuses, carry them back to the control room. Watch for sleeping Juggernauts in the rooms you pass and do not fire at them yet. Walk quietly past the dark machinery, put the fuses into the power breaker one after another and the lights come on. ULP then sends you toward the server room.

Wipe the servers

Go to the server room and open the SecuroServ app on your phone to connect to each server. You must stay within range until the upload reaches 100 percent. After the second server a failsafe sets off an alarm and the Juggernauts wake and attack with miniguns. Fight from behind the server racks, and with a team, let one player keep connecting while the others hold the enemy off.

Escape the silo

When the last server is wiped, head for the silo exit. The Juggernauts you saw earlier now hunt you, so move from room to room using doorways and corners, and shoot their heads and chests until they drop. Follow the marker back to the elevator; the corridor near the exit is lit red by the alarm, so do not stop there.

Escape Mount Chiliad

Outside, a hostile helicopter and Cliffford mercenaries attack, and your own helicopter is damaged. Take out the helicopter with a rocket launcher or heavy weapon from behind cover, then use the parachute nearby to drop down the mountain. Take a car at the bottom and drive to the IAA Satellite Relay Station while mercenaries in trucks chase you. Keep driving and the agent waiting there ends the mission.
