Talk to Kenny in Hackerspace to start this mission. After the cutscene, head to the Stache and Vine clothing store near your HQ and talk with Horatio to get the mission started. Find a vehicle then drive to the parking lot so you can ride the Nudle bus parked there.
Once you’re driving the bus, you have to follow the route to pick up more Nudle employees at designated bus stops. Continue doing this until you get off the bus automatically. This time, you have to follow Horatio inside the Nudle office to trigger a cutscene. After that, the mission will end.
