OPn the rooftop of said building, you can access to a zone where there is a lot of workers and roombas. Next to them there is a stair the will lead you to a chest.

On the central controls that you have to use to use the main elevator on the read factory there is another chest on a corner.

IN the same factory, there is a locked door in the street that you have to unlock from inside. There is a box there too.

Another one inside the favory, when you lift the main elevator in the middle, there is one on the elevator.

There is another one behind the stadium on Metro City. You need to use the stairs on the left and make a rising uppercut to go down (the road is closed by shops). Under it, you will find a fence and behind it there is several wood boxes and a sirn box hide next to a container.

For all of those following this guide, there is at least one left which is on the parking loot. You have to access to the first floor throught the spiral road.
