After the prologue in Rift Apart, you’ll be transported to the planet where Rivet is.
One of the optional objectives is to locate a resistance spybot in the factory.
Here’s a walkthrough on locating the resistance spybot on Corson V in Ratchet and Clank: Rift Apart.
The location of the factory is shown in the map below, marked by the optional objective symbol.
Head into the factory
The factory is located at the upper part of the city. Use the magnetic path to climb up.
Enter the factory from the front.
You’ll come across some enemies on the inside.
Use the rifts to get to the next part of the factory.
Enter the production line
Turn the screw to open the door.
If you ever get lost, just press R3 and they’ll show you where you need to go.
Inside the factory’s production area, keep heading deeper inside.
You’ll eventually reach an outdoor section again. Take out the enemies here.
Get the resistance spybot
Finally, you’ll reach the area where the spybot is kept. Take out all the enemies first.
After securing the area, get to the spybot and a cutscene will load. The optional objective ends here.
