No worries, Esme. I'll get into detail a bit about the images....

1. This is the outer path of Machine Sphere A (which is the largest of three similar areas) It shows how the giant protection rings (the, on the inside, glowy rings) are hooked up to the magnetic gliders.

2. This shows the protection rings up close, as well as a view of the scaffold connected to the Hardpoint Amplification Spike. You can also see where the tall hallways connect to the Machine Sphere

3. Hardpoint Amplification Spike (and scaffold). Containing up to 9 hardpoints, this machine delivers additional power to the hardpoints, compared to a regular hardpoint in say canyon or labspace. The clover-shaped platform at the bottom of the scaffold, is actuall 4 seperate platforms. You'd fit them to the HPAS if you need a few more hardpoints.

4. Access to the Machine Sphere (and HPAS scaffold) from the tall hallway.... untextured obviously.

5. another view of the outer path of the machine sphere

6-8. (Completely untextured, yet dummy vertex painted) Service Tunnels. These would outline the Machine Sphere's, and you'd access them from a hatch in the tall hallways. In the Service Tunnel, you'd have some additional control over ressource distribution to the HPAS. You'd have several completely new damage types and looks.

9. The HPAS in all their glory. In Machine Sphere A there was three. In the other two there would only be one in each.
You could even control stuff INSIDE the HPAS, by entering a small control room at the same level as the clover-shaped platforms. The gameplay was not yet designed though. But something about energy/ressource flow/control/distribution probably.

10. Another view of a HPAS, which reveals a lot more machinery below the platforms. If a HPAS is not fitted with the platforms, you'd have a good clean view of the exhaust thingies at the bottom.

11. The tall hallway. And one of the "hatches" on the sides, would lead to a service tunnel

12. Hovering over a HPAS you can see a Magnetic Field Generator (i think they were called). This would either boost energy or offer additional shielding. Can't remember. And obviously they were not meant to be floating in mid-air. There was some minor finalizing of the design, as well as set-dressing missing still (apart from all the obvious missing and dummy textures).

So - if anyone still roleplays Seed in one form or another, here's a little info to play with.
I do believe, that TechSpace would've been connected to the Canyon as well. Not entirely sure where though.

Cheers
