Get ready for the final Motherload mission, which unlocks when you've ticked off Power to the Sheeple, Robot Wars and Shanghaied from the DedSec app. We recommend unlocking the Mass Disruption and Blast Detonators research nodes before continuing. Good luck!
Blow It Wide Open
The opening of the mission has you play as other characters:
Sitara: Head across the rooftop to the objective marker to find a switch puzzle. As soon as you unlock the first switch a countdown will start, but apart from the time limit the puzzle is simple - unlock each switch in turn, rotate them so they connect to all the wires, and move on to the next one.
Wrench: Wrench is armed with a grenade launcher - it's not very accurate, but it does a lot of splash damage to compensate as long as you're careful not to hit anything too close to you. From the starting point head down the slope to the left, open the gate, and head past the steps ahead and open the door but don't go through it yet.
Turn around and sneak up the steps until you have a clear view of the top and throw a blast detonator against the wall. Use it to attract the attention of the nearby guard and then set it off to clear him out and get rid of a couple of explosive hazards. Move to the top of the steps and fire off a volley of grenades to clear out the guards then access the panel at the marker before heading back down the steps and through the door you opened earlier.
Close it behind you and take cover while the download finishes, and then head for the next marker. Once the dynamite is placed back off before it explodes, head through the hole to the server room, and fire a grenade at each of the computers.
Marcus: For most of this mission stealth is essential, and if the guards become alerted to your presence you may as well let yourself get mown down as there's very little chance of getting any further.
Once inside the lobby head down the steps to the right and take cover at the bottom. Send the quadcopter out, switch to NetHack, and locate the guard with the keycode to unlock the doors, and then head for the marker to the left. There are guards patrolling either side of the room you need, but if you distract the nearest one as they're moving away from the room, head inside, and then distract the other it will buy you enough time to hack the router.
Retreat back to the bottom of the stairs and move to the other end of the balcony. There's only one guard between you and the door ahead, so distract him and make a dash, and immediately take cover behind the boxes to the right and wait for the guard patrolling past the windows to get out of sight before you hack the second router.
Exit the room and take cover while you keep an eye on the guard by the window and one to the left that makes a circular patrol. When they're both a fair distance away either distract them individually or use a mass distraction, jump over the barrier, and run straight across to the water feature. Drop down the stairwell. Head down, and take cover round the corner.

Deploy the Jumper, switch to NetHack, and follow the red cable towards a vent near the floor - there's a single guard on patrol here that will need distracting on the final stretch. Head to the far end of the vent, distract the guard loitering nearby, and then head out and to the right to find a flight of stairs. Jump up them and follow the room round to the leftt then hack the panel to unlock the elevator.
Switch back to Marcus and head down the elevator. You're safe down here for now, so when you reach the locked door send the Jumper over to the other side of the room and up the steps to locate the panel to unlock them. Head through, climb the stairs at the end, and interact with the panel to start transmitting the data.
This will alert some guards who will come running in your direction, so make your way to the turn half way down the stairs, throw a couple of explosive charges into the room, and wait for the guards to come storming in before setting them off. Use a mass distraction to disable any survivors, push your way through, and sprint back to the elevator.
Back at the top don't hang around, and just sprint towards the exit - the mass distraction should have recharged by now so use it to cover your escape if you need, and once you open the lobby door you can sit back and watch the end unfold... Congratulations!
While the story is over, there is plenty yet to do - whether it's specific side-quests such as Ubistolen, $911 and Shadows, or other activities such as races, ScoutX, Driver SF and multiplayer - our Watch Dogs 2 walkthrough and guide covers it all.
