Grand Theft Auto V

Torpedo ECU (Preparation)

By
Shane Williams

This page is a walkthrough for The Doomsday Heist Preparation Mission, Torpedo ICU. It’ll navigate you through the necessary steps to successfully acquiring the Torpedo ECU

Overview of the Torpedo ECU mission.

Assault a barge off the coast and steal the torpedo electronic control units from arms dealers.

Go to Chumash / Steal the Torpedo ECU

Once you’ve started up the mission, take any car and follow the waypoint to Chumash. Upon arrival, take the Jet Ski and approach the barge, then take out the enemies from a distance before boarding. After the area is cleared, climb aboard the barge and take a duffel bag containing a Torpedo ECU.

(1 of 3) Head over to Chumash and steal a Jet Ski

Wait for the two enemy helicopters to approach you and take them down, then steal the helicopter thats on the barge and fly the Torpedo back to your Facility. Like always, you’ll be sending out a Global Signal, so beware that other players may try to interrupt.

If you’re playing solo, then you’ll need to return to the barge and steal the second Torpedo ECU, however you wont need to worry about enemies as they dont respawn.
