Walkthrough – Collectibles in Chronological Order

Early Game Collectibles

• 16 Gold (16/194): After the first enemy encounter, jump down to the platform, then another jump down. Instead of moving forward, turn around and head behind the platform to grab gold.
• Secret #1 + 6 Gold (22/194) + Ruby #1: After defeating enemies near a big green portal, don’t enter it yet. Go right in front of the portal, throw your shield onto the statue to access a bridge, then collect gold and the first ruby.
• Secret #2 + Codex Entry #1 (Temple of Lomarith): Enter the green portal and swim through the sunken shipwreck marked by green armor pickups. Before exiting, take the right path inside the shipwreck to find the secret area with the codex entry. This is one of the three underwater secrets for the Water Logged challenge.
• Secret #3 + 6 Gold (28/194): After leaving the shipwreck area, jump into the water, dive down, turn right near a lamp on the ground, and swim into the hole to find another underwater secret.
• Demonic Essence – Ammo #1: Proceed to the big open area with a leader. Defeat him to get the essence as part of the story.

Mid-Game Collectibles

• Secret #4 + 50 Gold (78/194): After the leader fight, destroy a wall near the main objective to find a gold box.
• 16 Gold (94/194): Climb the hill above the previous gold. Destroy a wall, enter a ship, turn right, jump down the ledge, go through a green portal, and turn left for two stacks of gold.
• Collectible Toy #1 (Cacodemon Hybrid): Inside the shipwreck, after defeating enemies, exit by throwing your shield through a wall. Before exiting, move the block holding the toy collectible. Then throw your shield through the eye symbol to open the door for the toy.
• 8 Gold (102/194): Re-enter the shipwreck and leave through the other exit. Go right and around the corner to find gold.
• Secret #5 + 6 Gold (108/194): After shield-bashing through a green ring, instead of jumping through the next ring, turn left and destroy a wall to enter another shipwreck with gold inside.

• 8 Gold (116/194): Jump through the second ring and go around the corner to find gold.
