Sector 3: Lava Pit
While your goal is the desert area, there is control safety hazard that is keeping the entrance locked. You'll instead return to the control room outside the volcano. With your speed booster you'll be able to easily cross any lava in your way. Once again the control room is guarded by a shelled enemy, however it is no match for your new toys. use the console in the middle of the room to unlock the route towards the desert.
Upon reaching the door leading towards the desert, you'll find Anthony fighting a losing battle with the horned enemy from Sector 2. Adam will allow use of your grapple beam, allowing you to reach the battle. Once again the horned enemy is too strong to kill, so instead lure it towards the lava. It will charge passed you, diving straight into the deadly magma.
Follow the waypoint all the way back to the grappling beam room from your first visit to Sector 3. Swing across projections to arrive at a giant pit of lava.
Gone Fishing
At first you'll only be able to move through the overhead duct, using your morph ball bombs to release several grappling pods. However, one of them will sink into the lava itself and gobbled by the monster below. You'll need to fetch it from this fast moving boss.
You'll want to shoot into the boss' mouth with fully charged shots or missiles to dead the most damage. You can also make use of your grapple beam to reel in the beast, leaving it beached on the rocks for a few seconds. This will expose its belly, another tender weakness that can deliver alot of damage. Follow up with a final overblast to restore the grapple device and lead a way to the desert.
