A Ghastly Voyage

You'll start moving down a swamp river lined with gravestones. These things spawn ghosts, so you'll need to destroy both the gravestones and the ghosts before they overwhelm you. It might take a few tries to get the hang of it, so don't get discouraged!

Keep an eye out for Pierre. His flaming heads usually miss, but he's still a nuisance. After the boat stops, you'll hit your first checkpoint. Blast through the barrier right in front of you and keep moving.

Pierre will pop up again, but you need to destroy his shield first before you can actually damage him. Past him, there's another barricade guarding two gravestones. You'll need to take out the Ghosts and the barrier simultaneously. Try sweeping back and forth, hitting the Ghosts and focusing on one side of the barrier to take down one gravestone, then switch to the other side.

Your next encounter is Pierre and a gravestone. It's best to destroy the gravestone first because Pierre's flaming heads are easier to dodge than the Ghosts. Once both are dealt with, head up the ramp behind them, blasting through any barriers you see. You'll reach another checkpoint shortly after.

As you round the corner past the checkpoint, prepare for a swarm of Ghosts. Before you can proceed, you'll need to destroy the barriers to your left. Position yourself so the Ghosts are almost in line with the barriers, then fire away. You'll need to adjust your aim a bit to hit the spirits as they come. Once you break through, take out the gravestone and Pierre, then move forward to a fork in the path.

At the fork, two Pierres will start launching heads at you. The good news is they attack at the same time and in the same spot, making them relatively easy to dodge. Don't linger in one place too long, but pick a side and stick to it while you destroy their shields and fire on them.

Your biggest challenge is up next: three gravestones. Your main focus here is survival, but keep an eye out for openings to destroy barriers and gravestones. After you take out the last one, Sly will jump off the skiff and grab the key. You're almost done with this world!
