Lost Island (part 2)

Great, you've fallen through a trap door and are now separated from your team. Oh well--proceed through the corridor, being careful of the black slime, and duck into a tunnel on the right. It'll soon lead you to a second tunnel--equip your Overload Pulse as you'll be facing some spider baddies as you venture through.

Inside the second tunnel, head right first to find the Old Captain's Wheel artifact, then proceed the opposite way. You'll soon reach an expansive room with the entire center floor blanketed in black slime. Follow the walkway left, to a gate on the opposite side. Once there, use the Slime Tether to pull both weights on either of the gate to the floor, causing the gate to raise and draining the room.

With the room cleared, two large Black-Slime monsters will appear, in addition to several small spiders. While you can attack the Slime Creatures from a distance, it's actually easier to get close and take them down with the Shock Blast. If one attempts to charge you while on the walkway, simply run past him to evade his attack. Afterward, clean up the remaining spiders using the Overload Pulse, then look for a tunnel you can enter on the lower level.

Keep your Overload Pulse equipped as you venture through the tunnel, as you'll come across several spiders. When you reach the split path, head right for a Ghostbusters DVD artifact, then continue down the other direction. Before long, you'll emerge in a bright room, with Winston radioing in for help. Look for him inside the vertical coffin-looking thing, just a few feet left of where you entered from--interact with it to free him. Now follow him up the stairs and through a door he kicks open.

Through the door, head dead-ahead to find a Weird Color Jars artifact on the left, then climb the stairs and head to the far right corner. There you'll battle a couple of ghosts and more black-slime creatures--use the Shock Blast on the creatures, then use either the Plasma Beam or Overload Pulse on the ghosts. Afterward, follow Winston down the stairs and through the door a ghost blows open.

Inside the next room, open the coffin-thing on the right to free Egon, then get ready to take on a whole mess of enemies, including more ghosts, black-slime creatures, and one large black-slime monster. Because of the enemies will be in your face, stick to the Shock Blast--you should even be able to get close enough to the ghosts to make effective use of this weapon. Oh, and when the Slime Monster shows up, circle around him while blasting him. Just remember to keep an eye on your teammates and revive them when necessary so you've got backup.

After clearing the room, ride the lift (opposite the entrance) to the floor above and follow your squad to the next room, where you'll find an odd-looking machine in the center. Climb the stairs to the second floor, then use your grapple beam on the three balls floating around the machine and slam them downward, setting them in place. Unfortunately, this has the side-effect of summoning the level's boss--but thankfully, he's a push-over.

The boss begins the battle with several eyeballs floating around him, near your level--they're weak, so almost anything will take them down. With the eyes defeated, a glowing weak-point will appear on the boss's head. Its most vulnerable to slime, so equip the Slime Blower! Because the boss attacks frequently, keep on the move at all times, by strafing back and forth along the length of the walkway--as long as you keep moving, he'll always miss. While doing so, continually spray slime toward his weak-point to inflict damage. After dealing enough pain, he'll lower his head to your level briefly, making it even easier to target! Keep it up--he'll call it quits soon.
