Sector 3: Volcano
Before actually entering inside the volcano, you'll be inside another interior control center. You'll be attacked by a gang of Space Pirates, but with your new ice weapon they can be defeated even easier. When ready, activate the panel ahead and move through the ducts.
You'll arrive inside the volcano, and the lava will start rising. You need to quickly ascend and move to the right. If you're caught in the molten river you'll take heavy damaged and be slowed by its pull. Make your way to the top of the volcano and you'll soon find yourself face to face with a new fearsome boss.
Lava Beast
Adam will finally authorize the use of your varia suit, which will finally prevent you from taking constant environmental damage. The boss has noticeable weak points that you should first freeze, then assault with a missile. After a short while it will change its patern and start slamming the ground. During this time freeze its arms and room up them to devliever a devastating overblast. One or two of these finishing moves will be enough to kill off the boss for good.
After the battle, the lava will finally stabilize. Descend back down into the volcano and follow the waypoint to the new path. You'll come to a area that requires the grapple beam, however Adam will instruct you to head to Sector 2 instead. Backtrack towards the sector elevator and you'll be attacked by another shelled enemy. Your tactics from the previous encounter will work just as well. When this enemy is killed, return to the Main Sector and into the blue elevator to Sector 2.
