There's only one path to go, so follow it until you have to glide down to a larger area, where you'll find a weapons vendor, as well as an armor one. There are two new weapons to buy there, the Plasma Striker and the Nether Blades, as well as a new armor if you didn't buy it on Planet Kragg. If you go on the path behind the vendors, you'll find a room with another RYNO VII part.
There's another dead end with a piece of the floor missing that houses some Raritanium. To continue, go opposite the path with the RYNO part and you'll find a plant spawning some enemies. Destroy it and you should see a Battery Bot running around. Grab it, bring it back to the main area and toss it into the receptable at the end. This will make the train move and extend the bridge, spawning two Nethers.
Take them out and follow the path until you see a very short scene with a turret. Glide down and go to the right of the red light to avoid it, then keep going for another scene. The main path is blocked by turrets ahead, so you'll need a detour. There's an empty socket nearby, which also means there's a battery bot as well.
If you look around, you can find a ledge to hop up on with another turret guarding the bot you need. Use the Comet Strike (hold L1, then press Square) to grab it and place it into the socket. This will cause some Swingshot targets to appear, so swing to the other side and you'll find quite a few Thugs hanging out. Defeat them all and glide down to the next ledge.
