Chapter 7: An Emerald Mystery (Flare Pool)

Approach Flare Pool and use the launcher on the right to reach rocks on the other side. Drop off the east side to find a LARGE SHOT EXPANSION (12/44), which grants 20 ammo. Optionally, scan the Lamorn Statue on the east ledge for lore.

Descend and use the Spinner to enter Flare Pool.

To clear the magma blockage, freeze it with an Ice Shot and smash it with a Missile. Quickly pass through the gap before it refills. Boost into the nearby Spinner to permanently turn off the magma flow.

Continue down the path. Freeze and smash the magma flow on the left to reveal a MISSILE EXPANSION (22/48). Note the Save Station to the right.

Ride across the Lava Lake Bridge using the Vi-O-La's IC upgrade. On the far side, on the right, use the Psychic Boost Rail: scan it to solidify, roll in, and Boost through to reach a SHOT EXPANSION (13/44). You will arrive in the northeast corner.

Hop over bollards and enter the door on your left.

Activate the elevator in the Service Elevator room and ride up.

In the Undercarriage, a security shutter blocks the normal route. Roll into the vent to the door's right, which requires the Fire Shot to burn off the mesh covering.

In Ventilation Works, roll into the spinner to reveal the exit. Defeat the Beam Turret. Look west and scan the yellow marker to remove the security shutter leading back. To bypass the next security shutter, Missile the glass window to its right.

Roll into the next pipe and Boost Ball up the right side onto a ledge. Exit via the door.

In the Undercarriage, activate and ride the elevator up. To the north, scan the clamp on a gate and pull it off with the Lasso to lower the gate. Scan the elevator behind it and ride down.

In the lower area, scan the marker next to the shutter to release it. Toss a Missile into the broken grating on the south wall to reveal a SHOT EXPANSION (14/44). Ride the elevator back up and exit via the east-facing door.

In the Inspection Station, go to the southeast corner, burn off the mesh covering a tunnel with the Fire Shot, and roll into the under-passage. Bomb away the Tank and reach the SHOT EXPANSION (15/44). Exit via the east door.

In Entry Bay, you will be attacked by a Heavy Maintenance Tank. Stay airborne to avoid its laser attacks and hit its head with Missiles. After defeating it, find the Log in the southwest corner. The south door leads to Material Processing (with a Turret) and a Save Station. Your path forward is the north door.

Pass through the Thermal Siphon hallway.

In the Boiler Room, enter the circular tunnel on the west wall and roll into the room with the spinning boiler. Enter the next tunnel to reach Sgt. Duke. Speak to him, then scan the console behind him. Activate the switch to open the Spinner in the center room. Roll back and rev up the Spinner. Shoot each of the four sides of the boiler core with an Ice Shot. You can hit one panel and then roll into a ball to wait for a safe moment, or spam Ice Shots and tank the damage. A Save Station is available back the other way.

Fight the pair of Maintenance Tanks in the Thermal Siphon hallway.

Head for the eastern door in Entry Bay. With Sgt. Duke, you can both tap switches to open the way forward.

Pass through the cooling rings in the Cooling Room.

In Energy Extraction, walk clockwise around the room. Find an elevator and scan it to ride up. Blast the Turret in the observation room and scan the console to open a hatch across the room. Clear the grate to your left with a Missile and fire a Control Beam through it. Steer it around the center of the room to the hatch on the opposite side.
