I tried to take wide shots that will help you locate it easily from a landmark like the drop pod.

These give you items:


In the rafters, on the left when looking towards the launch pod.

---

Underneath the floor in the recreation sphere. There are 4 levers to lower the floors, the nearest is the rear left. I've added additional image to show the floor switch and the highlight toggle near the box.

---

In a small opening on the wall to the left of the launch pod right of the SAXON logo.

---

Inside the ventilation duct above all the chip bags.

---

These are just other things:

The pipe to knock over.

---

Weird mushroom thing that talks.

Access to cars in the hub. The wall is broken open between mission control and the staircase. Use the switch to open the doors which should save being open in future lobbies.

I know it isn't HUB related, but you do make these edits in the hub ;) and its pictures so I'm uploading them. I'm not positive exactly how these work... It just gives you a random drop when you place upgrades so that these shapes are made, that much is obvious but I'm not sure how or if they are shared between weapons/classes. For now I will label them how I found them. Let me know and I will update this section.
(Currently I suspect each weapon/class has a single hidden path.)
