Part 19

Follow halls until you reach a forcefield. Spirit walk (use spirit form to pass through solid objects) past it, then hit the switch on the right to disable it.

Return to your body and exit through the door ahead. Kill the hunters.

Ignore the switch in this room for now. Go through the orange portal and stand on the elevator.

Enter spirit form and spirit walk over the visible bridge to the other side. Activate the touch screen monitor to open an orange portal back to the previous room.

While still in spirit form, use the switch to lower the elevator you are standing on. Crouch through the portal.

Enter the next area, find the hole in the floor, and fall to the bottom.

Destroy the security turret and drones. Look up and shoot the gravity switch. Walk around any open fire pits.

Position yourself over the bridge with the gravity switch and shoot it again. Take ammo from the wall-mounted container.

Step back out into a new area. Follow the walkway to the gap. Ensure the flying harvester is dead before spirit walking over the gap via the bridge.

Use the switch on the other side to activate wallwalk (allows walking on walls).

Move back past the door you entered from and take the wallwalk to the opposite platform.

Walk to the shuttle pad on this side and spawn a shuttle.

Aim the shuttle's cannons at the tractor beam devices on the walls and destroy them.

Pilot the ship to the top of the area and exit through the two gates.

Exit the shuttle on the shuttle pad in the next area, kill nearby enemies, and walk onto the pipe leading to the small planetoid.

Walk around the planetoid until you are over the platform with a touch screen monitor. (The platform with the shuttle pad has a regular display monitor, not the correct one).

Once located, stand over the platform, enter Spirit form, fall through the forcefield, use the touch screen to turn it off, and return to your body.

Locate another touch screen monitor on a platform with a nearby shuttle pad. Press it to open the tunnel.

Get back in the shuttle and fly up through the tunnel.

On the lower planetoid, exit the shuttle on the shuttle pad. Fight off drones and move straight away from the shuttle controls.

Jump on the pipes and follow them up to the upper planetoid. Press the touch screen monitor.

Follow the pipes back down to the shuttle pad on the planet below. Enter the shuttle and fly towards the plasma shooting objects.

Fly near the object, wait for the blue plasma to stop, then fly up it and turn right to enter the next area.

Destroy the energy tower by destroying the small objects attached to the rotating metal plates.

The objects and tower shoot electricity; use the shuttle pad to recharge if needed.

Once all objects and plates are detached, destroy the rings in the middle of the tower.

After the tower explodes, pilot the ship up through the opening in the ceiling.

Exit the ship on the shuttle pad and step through the blue portal to finish the level.
