Walkthrough[]
The recent gains in raritanium should provide a significant boost, allowing you to enhance the stats of your preferred weapons at the weapons vendor. It's recommended to invest some of it in upgrading weapons that may be falling behind in terms of power and usability. In the Hall, the main defenses consist of floating mines in water pools. You can safely navigate through these pools by utilizing the Hydro-Pack and O2 Mask. The Hydro-Pack enables quick swimming, while the O2 Mask allows you to swim without the need to breathe.
Proceed through the first pool, avoiding the mines, and then exit it to destroy the cyclocannon obstructing your path in the next corridor. In the subsequent pool, you must activate the tri-pads located around the pool's perimeter to reveal an underwater tunnel. Be cautious of the mines in the tunnel. Continue deeper into the Hall until you reach another pool, where you'll encounter giant jellyfish. At the bottom of the pool, there are stacks of crates and a raritanium chest. Trigger the nearby explosive crates, swim away, and wait for the explosion before collecting the spoils.
Rotate the bolt crank on the platform in the middle of the pool to bring the giant jellyfish to the surface. Use one as a platform to reach a gold bolt, while another giant jellyfish can be used to climb a ladder, leading to a tube. Proceed to the end of the tube, but hold off on jumping down immediately. Instead, jump into the tube on the other side of the wall to access another chest. Afterward, jump down to encounter a group of sentries, followed by shielded sentries and a trio of gunships that attack through the windows. Clearing out all the enemies triggers a cutscene, after which you automatically escape the planet and travel to Fastoon to embark on the mission "Explore the Lombax City".
